The workspace had two layouts, compact and split, and only an unfolded iPhone Duo in portrait floated its sidebar. Windows between 600 and 720 points wide got the phone stack.
deriveLayout now returns a width class: compact, medium (600–720 points wide) or expanded. On a medium window the Android shell places the sidebar beside a list. Over a page it floats the sidebar above a scrim: tapping the scrim or pressing Back closes it, and so does opening a page from it. The rail shows and hides with the sidebar. Back closes a sheet on top before it closes the sidebar, and the page underneath is hidden from accessibility while the sidebar is open.
Part of the workspace split: router → shell → feature screens → design system → native. Stacked on #26741.

Mobile layout classification now distinguishes compact, medium, and expanded variants. Medium layouts can display a floating sidebar with dismissal behavior. Workspace navigation and thread sizing now use the updated layout variants.
Changes: Mobile layout behavior
| Layer / File(s) | Summary |
|---|---|
Layout variants and pane sizing apps/mobile/src/lib/layout.ts, apps/mobile/src/lib/layout.test.ts | Layout derivation selects compact, medium, or expanded variants. Pane sizing accounts for whether the primary sidebar floats. Tests cover width and height boundaries. |
Floating sidebar behavior apps/mobile/src/features/layout/AdaptiveWorkspaceLayout.tsx | Medium layouts can display a floating sidebar with animated positioning, a dismissible scrim, accessibility handling, and Android Back handling. |
Workspace navigation integration apps/mobile/src/features/layout/createWorkspaceStackNavigator.ios.tsx, apps/mobile/src/features/layout/useSidebarToggle.ts, apps/mobile/src/features/workspace/* | Workspace navigation, sidebar toggling, tab rendering, dock clearance, and system tab-bar eligibility now use the medium variant. |
Thread layout sizing apps/mobile/src/features/threads/ThreadDetailScreen.tsx, apps/mobile/src/features/threads/ThreadFeed.tsx | Thread detail and feed layout checks now treat non-compact variants as wider layouts. |

| 142 | # UIAccessibility |
| 143 | |
| 144 | A set of methods that provides accessibility information about views and controls in an app’s user interface. |
| 145 | |
| 146 | ## Overview |
| 147 | |
| 148 | The `UIAccessibility` informal protocol provides accessibility information about an app’s user interface elements. Assistive apps, such as VoiceOver, convey this information to users with disabilities to help them use the app. |
| 149 | |
| 150 | Standard UIKit controls and views implement the `UIAccessibility` methods and are accessible to assistive apps by default. This means that if your app uses only standard controls and views, such as `UIButton`, `UISegmentedControl`, and `UITableView`, you need only supply app-specific details when the default values are incomplete. You can do this by setting these values in Interface Builder or by setting the properties in this informal protocol. |
| 151 | |
| 152 | The `UIAccessibilityElement` class, which represents custom user interface objects, also implements the `UIAccessibility` informal protocol. If you create a completely custom UIView subclass, you might need to create an instance of `UIAccessibilityElement` to represent it. In this case, you’d support all the `UIAccessibility` properties to correctly set and return the accessibility element’s properties. |

| 233 | # Accessibility for UIKit |
| 234 | |
| 235 | Make your UIKit apps accessible to everyone who uses iOS and tvOS. |
| 236 | |
| 237 | ## Overview |
| 238 | |
| 239 | Making your app accessible means making it usable by everyone. By designing your app with accessibility in mind, you make it possible for everyone to enjoy your app. For more information, see Accessibility. |
| 240 | |
| 241 | UIKit controls and views come with built-in accessibility, providing an accessible user experience by default. Typically, you don’t need to do extra work to enable the standard accessibility features. |
| 242 | |
| 243 | In some cases, you might want to modify the default values to better represent your app, to provide additional context, or to modify the user’s flow through the app. UIKit makes these customizations straightforward, involving a few lines of code or Interface Builder adjustments as you define your user interface. For more information about customizing accessibility for UIKit elements, see UIAccessibility. |
| 244 | |
| 245 | If your app contains custom user interface elements that don’t inherit from `UIView` or one of the other UIKit classes with built-in accessibility, make those elements accessible by subclassing `UIAccessibilityElement`. |
| 246 | |
| 247 | If you build your app with SwiftUI, see Accessibility modifiers. |
| 248 | |

| 18 | |
| 19 | The value of this property is a floating-point number in the range `0.0` to `1.0`, where `0.0` represents totally transparent and `1.0` represents totally opaque. Changing the value of this property updates the alpha value of the current view only. However, the transparency imparted by that alpha value affects all of the view’s contents, including its subviews. For example, a subview with an alpha value of `1.0` that is embedded in a parent view with an alpha value of `0.5,` appears onscreen as if its alpha value is also `0.5`. |

| 220 | # Supporting VoiceOver in your app |
| 221 | |
| 222 | Add VoiceOver support to make your iOS app more accessible to users who are blind or have low vision. |
| 223 | |
| 224 | ## Overview |
| 225 | |
| 226 | VoiceOver is a gesture-based screen reader that enables people to experience the interface on their devices without having to see the screen. People who are blind depend on VoiceOver to provide auditory feedback while using their iOS devices, but VoiceOver isn’t exclusively for users who are blind or have low vision. For example, someone prone to motion sickness might choose to turn VoiceOver on while they’re in a moving vehicle. VoiceOver assists all types of people, but those who are blind rely on VoiceOver whenever they use their devices. |
| 227 | |
| 228 | With a few steps, you can make your app VoiceOver-accessible in Xcode or programmatically. By increasing accessibility, you open your app to a wider audience, and make it easier for everyone to use. |
| 229 | |
| 230 | ### Audit your app with VoiceOver on |
| 231 | |
| 232 | To test the accessibility of your app, turn on VoiceOver and navigate through the interface. By using your app with VoiceOver on, you can establish a baseline of its accessibility. To start auditing, choose Settings > Accessibility > VoiceOver, and enable VoiceOver. Then, open your app and use the specified action whenever you want to test VoiceOver. |
| 233 | |
| 234 | Auditing reveals which elements are accessible with VoiceOver and which aren’t, and shows you if VoiceOver navigation is clear and logical. Keep track of which elements aren’t accessible, and create a list of improvements for adding better VoiceOver support. |
| 235 | |
| 236 | ### Navigate with VoiceOver on |
| 237 | |
| 238 | To audit your app with VoiceOver on, you use VoiceOver’s unique set of gestures to navigate your app. For testing, there are five key gestures that you may use: |
| 239 | |
| 240 | * Swipe left or right to navigate to the next or previous UI element. |
| 241 | |
| 242 | * One-finger double-tap to activate the selected element. |
| 243 | |
| 244 | * Two-finger tap to stop and resume speaking. |
| 245 | |
| 246 | * Swipe up with two fingers to read everything onscreen. |
| 247 | |
| 248 | * Three-finger triple-tap to turn Screen Curtain on and off. |
| 249 | |
| 250 | To learn more, see Operate iPhone using VoiceOver gestures. |
| 251 | |
| 252 | To replicate the experience of someone who is solely relying on VoiceOver, test your app using Screen Curtain. As the name implies, Screen Curtain blacks out the entire screen. You can still navigate using VoiceOver gestures, but you can’t see the elements on the screen. |
| 253 | |
| 254 | ### Identify common accessibility issues |
| 255 | |
| 256 | To audit your app, check that you can access every element and that the ordering of those elements is what you intend. Take note of which elements VoiceOver can or can’t access. Also, pay attention when you find it difficult to perform a task because you assume it’s reliant on visuals. For example, when you’re navigating back to your app’s initial view, or you’re sharing content with another app or user, how can you use VoiceOver to make it accessible? While auditing your app, here are some common issues to look for: |
| 257 | |
| 258 | * Add accessibility information for your app’s elements. VoiceOver doesn’t recognize custom UI elements by default. You need to add additional accessibility information to those elements. |
| 259 | |
| 260 | * Group elements so that VoiceOver navigates through them in the correct order. VoiceOver reads from the leading to the trailing edge. If you want VoiceOver to read your elements in a different order, use groups to facilitate navigation that makes sense for your app. |
| 261 | |
| 262 | * Include descriptive text for VoiceOver to read. A UI that depends on visual cues may look nice, but it can be unusable for a VoiceOver user. For example, VoiceOver doesn’t detect if a confirmation button turns from gray to green when the user selects it. VoiceOver may only describe the element and not its current state. Make sure that VoiceOver says whether the button is in a selected state. |
| 263 | |
| 264 | When you know which areas need improvements, start adding greater VoiceOver support to your app. |
| 265 | |
| 266 | ### Update your app’s accessibility |
| 267 | |
| 268 | For elements that aren’t accessible to VoiceOver, start by improving their accessibility labels and hints. The `accessibilityLabel` property provides descriptive text that VoiceOver reads when the user selects an element, and the `accessibilityHint` property provides additional context (or actions) for the selected element. |
| 269 | |
| 270 | Accessibility labels are very important because they provide the text that VoiceOver reads. A good accessibility label is short and informative. It’s important to note that a `UILabel` and an `accessibilityLabel` are different things. By default, VoiceOver reads the text for standard UIKit controls, such as `UILabel` and `UIButton`. However, these controls can also have corresponding `accessibilityLabel` properties to add more detail about the label or button. |
| 271 | |
| 272 | Depending on the context, hints aren’t always necessary. In some cases, the label provides enough context. If you feel like you’re saying too much in an accessibility label, consider moving that text into a hint. |
| 273 | |
| 274 | To ensure that users understand the intent of your interface, you might need to set some accessibility labels manually. You can set accessibility labels and hints in Xcode’s Identity inspector, or programmatically. |
| 275 | |
| 276 | ### Add accessibility labels and hints using the Identity inspector |
| 277 | |
| 278 | When using standard UIKit controls, assign accessibility labels and hints in Xcode using the Identity inspector’s Accessibility pane. To improve accessibility, you make an element accessible by selecting the Accessibility Enabled option. For example, the play button in a music app might include the following label and hint: |
| 279 | |
| 280 | Image: An Xcode screenshot showing the Accessibility pane of the Identity inspector. This pane has a checkbox to enable accessibility, and three text fields to enter text for an object’s label, hint, and identifier. The Accessibility Enabled option is in a selected state. The Label field says Play Song, the Hint field says Play the selected song, and the Identifier field is blank. |
| 281 | |
| 282 | ### Add accessibility labels and hints programmatically |
| 283 | |
| 284 | There are times when adding accessibility labels and hints in Xcode isn’t enough, such as when you’re working with custom UI elements that VoiceOver doesn’t automatically recognize, or if you’re using variables as part of your accessibility labels. In those situations, you need to set the accessibility labels or hints programmatically. You specify that an element is an accessibility element, and then create a corresponding accessibility label and hint. |
| 285 | |
| 286 | To make your element accessible to VoiceOver programmatically, define it as an accessibility element. |
| 287 | |
| 288 | `score.isAccessibilityElement = true |
| 289 | ` |
| 290 | |
| 291 | An element’s label might not stay the same throughout the entire life cycle of your app. For example, for a counter that keeps score as you play a game, you want to change the label as the score changes. Do this programmatically by setting the accessibility label and hint. |
| 292 | |
| 293 | `score.accessibilityLabel = "score: \(currentScore)" |
| 294 | score.accessibilityHint = "Your current score" |
| 295 | ` |
| 296 | |
| 297 | ### Simplify your accessibility information |

| 299 | VoiceOver reads in the direction of the device’s language. For example, VoiceOver reads English from left-to-right and it reads Arabic and Farsi from right-to-left. If you vertically stack labels in a UI, or display text in a table, VoiceOver may not read the labels in the correct order. VoiceOver reads the first group before reading the second group.】 |
| 300 | |
| 301 | In the image above, there are four labels on the left that VoiceOver reads from the leading to the trailing edge, in this case, left-to-right. Although every element is accessible to VoiceOver, this doesn’t provide the best user experience. On the right, VoiceOver reads the grouped labels in the intended order, which allows clear navigation. |
| 302 | |
| 303 | To group the labels, create a `UIAccessibilityElement` and add the information you want to group together. |
| 304 | |
| 305 | `var elements = [UIAccessibilityElement]() |
| 306 | let groupedElement = UIAccessibilityElement(accessibilityContainer: self) |
| 307 | groupedElement.accessibilityLabel = "\(nameTitle.text!), \(nameValue.text!)" |
| 308 | groupedElement.accessibilityFrameInContainerSpace = nameTitle.frame.union(nameValue.frame) |
| 309 | elements.append(groupedElement) |
| 310 | ` |
| 311 | |
| 312 | Including an accessibility label for each element and grouping elements allows people who depend on VoiceOver to navigate their devices and use your app. |

| 331 | # UIAccessibility |
| 332 | |
| 333 | A set of methods that provides accessibility information about views and controls in an app’s user interface. |
| 334 | |
| 335 | ## Overview |
| 336 | |
| 337 | The `UIAccessibility` informal protocol provides accessibility information about an app’s user interface elements. Assistive apps, such as VoiceOver, convey this information to users with disabilities to help them use the app. |
| 338 | |
| 339 | Standard UIKit controls and views implement the `UIAccessibility` methods and are accessible to assistive apps by default. This means that if your app uses only standard controls and views, such as `UIButton`, `UISegmentedControl`, and `UITableView`, you need only supply app-specific details when the default values are incomplete. You can do this by setting these values in Interface Builder or by setting the properties in this informal protocol. |
| 340 | |
| 341 | The `UIAccessibilityElement` class, which represents custom user interface objects, also implements the `UIAccessibility` informal protocol. If you create a completely custom UIView subclass, you might need to create an instance of `UIAccessibilityElement` to represent it. `】 |
| 342 | |

| 348 | |
| 349 | `var accessibilityAttributedUserInputLabels: [NSAttributedString]!` |
| 350 | |

| 385 | ### Animate views |
| 386 | |
| 387 | Changes to several view properties can be animated — that is, changing the property creates an animation starting at the current value and ending at the new value that you specify. The following properties of the `UIView` class are animatable: |
| 388 | |
| 389 | * `frame` |
| 390 | |
| 391 | * `bounds` |
| 392 | |
| 393 | * `center` |
| 394 | |
| 395 | * `transform` |
| 396 | |
| 397 | * `alpha` |
| 398 | |
| 399 | * `backgroundColor` |
| 400 | |
| 401 | To animate your changes, create a `UIViewPropertyAnimator` object and use its handler block to change the values of your view’s properties. The `UIViewPropertyAnimator` class lets you specify the duration and timing of your animations, but it performs the actual animations. You can pause a property-based animator that’s currently running to interrupt the animation and drive it interactively. For more information, see `UIViewPropertyAnimator`. |
| 402 | |
| 403 | ### Threading considerations |
| 404 | |
| 405 | Manipulations to your app’s user interface must occur on the main thread. Thus, you should always call the methods of the `UIView` class from code running in the main thread of your app. The only time this may not be strictly necessary is when creating the view object itself, but all other manipulations should occur on the main thread. |
| 406 | |
| 407 | ### Subclassing notes |
| 408 | |
| 409 | The `UIView` class is a key subclassing point for visual content that also requires user interactions. Although there are many good reasons to subclass `UIView`, it is recommended that you do so only when the basic `UIView` class or the standard system views do not provide the capabilities that you need. Subclassing requires more work on your part to implement the view and to tune its performance. |
| 410 | |
| 411 | For information about ways to avoid subclassing, see Alternatives to subclassing. |
| 412 | |
| 413 | |
| 414 | * `autoresizingMask` - Provides automatic layout behavior when the superview’s frame changes. These behaviors can be combined with constraints. |
| 415 | |
| 416 | * `contentMode` - Provides layout behavior for the view’s content, as opposed to the `frame` of the view. This property also affects how the content is scaled to fit the view and whether it is cached or redrawn. |
| 417 | |
| 418 | * `isHidden` or `alpha` - Change the transparency of the view as a whole rather than hiding or applying alpha to your view’s rendered content. |
| 419 | |
| 420 | * `backgroundColor` - Set the view’s color rather than drawing that color yourself. |
| 421 | |
| 422 | * Subviews - Rather than draw your content using a `draw(_:)` method, embed image and label subviews with the content you want to present. |
| 423 | |
| 424 | * Gesture recognizers - Rather than subclass to intercept and handle touch events yourself, you can use gesture recognizers to send an action to a target object. |
| 425 | |
| 426 | * Animations - Use the built-in animation support rather than trying to animate changes yourself. The animation support provided by Core Animation is fast and easy to use. |
| 427 | |
| 428 | * Image-based backgrounds - For views that display relatively static content, consider using a `UIImageView` object with gesture recognizers instead of subclassing and drawing the image yourself. Alternatively, you can also use a generic `UIView` object and assign your image as the content of the view’s `CALayer` object. |
| 429 | |
| 430 | Animations are another way to make visible changes to a view without requiring you to subclass and implement complex drawing code. Many properties of the `UIView` class are animatable, which means changes to those properties can trigger system-generated animations. Starting animations requires as little as one line of code to indicate that any changes that follow should be animated. For more information about animation support for views, see Animate views. |

Hide the scrim from accessibility during its close animation.
When floatingSidebarOpen becomes false, pointerEvents changes immediately, but the scrim opacity animates to zero. During that animation, Android can still expose the labeled Pressable because its ancestor alpha remains greater than zero. Android excludes it only after the alpha reaches zero, so the issue is transient rather than persistent in the fully closed state.
Add explicit accessibility exclusions:

Default the optional layout variant before these comparisons.
layoutVariant is optional, but undefined !== "compact" classifies omitted callers as non-compact. This starts the feed with a viewport width of 0 instead of windowWidth, changes horizontal padding from 16 to 20, and can select scrollableAxes for Duo native insets. ThreadDetailScreen supplies a fallback, but ThreadFeed declares its own optional prop. (raw.githubusercontent.com)

✅ Confirmed as addressed by @juliusmarminge
Fixed in e883856: ThreadFeed now reads layoutVariant ?? "compact" once and uses it for the initial viewport width, the horizontal padding and the Duo inset behaviour. Its only caller, ThreadDetailScreen, always passes a variant, so this only changes direct renders such as the filePreview tests.
@juliusmarminge Thanks. The change you describe addresses all three comparisons and preserves behavior for explicit variants. The fallback covers direct renders that omit layoutVariant, such as the filePreview tests.
