The pinned expo-device-hub lists only iOS simulators with usage history. On a fresh runtime, Device Setup therefore says no simulator is available even though CoreSimulator has available devices. This is #16083, including the maintainer's request to verify current hub 0.15.3 on macOS.

Merge available iOS devices from xcrun simctl list devices --json into the hub inventory, following the existing Android AVD supplementation. Use the destination host's command runner and platform availability for both local and SSH hosts. Keep existing hub entries, omit unavailable/non-iOS devices, and retain discovered devices with a bounded warning if enumeration or decoding fails.

Current candidate: c70583d066, including main e455200077ce. Failed SSH probes preserve cached platform availability. An incomplete iOS supplement warns without filtering valid discoveries; empty failed inventories still retain cached entries. The existing SSH case now covers Android-only probe failure and recovery. Service-level cases verify iOS entries remain visible and open successfully after command/JSON/schema failures. These four cases failed before the review fix. vp run check:changed passes 99 tests across five files and all related checks. Removed a duplicate host-ID-only test case; SSH routing remains tested through the SSH host.

Earlier native inventory verification on macOS arm64, Node 26.12.1, installed iOS 26.3 runtime (not repeated for this integration):

  • Confirmed the published expo-device-hub@0.15.3 still filters devices whose last-used/last-booted timestamps are absent. Several installed devices have neither timestamp.
  • Called its actual /api/devices request handler without opening a listening server, then ran the changed DeviceHubOperations with that response and the real host command. Runtime result:
    json
    1{"hubVersion":"0.15.3","before":1,"after":11,"newIPhoneAir":true,"newIPad":true,"allShutdown":true}
  • The local/SSH regression cases failed before the fix because the never-booted iPad was missing, and pass afterward. Cases also cover deduplication, unavailable/non-iOS exclusion, command failure and malformed JSON without losing the hub inventory.
  • vp run check:changed: all checks passed, including 53 tests across four device test files, affected typechecks, lint, format, knip and generated GraphQL.

No device was created, booted, reset or deleted. No browser, native UI, remote SSH machine, or simulator boot was tested; SSH command routing is covered by focused fixtures. No UI or wire-schema changes. Existing device operations remain shared by clients and agent tools.

Fixes #16083.

Walkthrough

Device listing now supplements the hub’s iOS simulator inventory with available simulators reported by xcrun simctl. Local and SSH device hosts provide iOS and Android availability to guide simulator and Android AVD discovery.

Changes: iOS simulator discovery

Layer / File(s)Summary
Provide platform availability
apps/server/src/device/DeviceHubOperations.ts, apps/server/src/device/LocalDeviceHost.ts, apps/server/src/device/SshDeviceHost.ts, apps/server/src/device/SshDeviceHost.test.ts, apps/server/src/device/DeviceMultiHost.test.ts, apps/server/src/device/DeviceService.test.ts		Device operations accept a combined iOS and Android availability result. Local and SSH hosts provide the result. SSH tests cover availability probing and probe failures. Test fixtures use the updated options.
Merge simctl simulators
apps/server/src/device/DeviceHubOperations.ts, apps/server/src/device/DeviceService.test.ts, apps/server/src/device/SshDeviceHost.test.ts		When iOS is available, listing decodes simctl output and adds available iOS simulators missing from hub inventory. Command or decode failures mark iOS discovery incomplete. Tests cover simulator filtering, failure cases, and updated command fixtures.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Share one SSH platform probe per inventory refresh.

DeviceOperations.list evaluates iosAvailable and androidAvailable sequentially. Each effect runs probe, which starts a separate SSH probe. This adds two remote platform probes to every refresh.

Do not reuse remote.platforms directly. That value is captured during connectOnce, while platformAvailability performs a fresh probe and updates the current summary. Run one probe per list call and derive both availability values from its result.

✅ Addressed in commit 4618175

NnateEc19d ago

Confirmed and fixed in 4618175931. Each list refresh now obtains both platform flags from one fresh SSH probe and updates the host summary. It does not reuse the startup snapshot. The regression initially failed with [probe, probe]; it now verifies one probe on each of two consecutive refreshes after platform availability changes. All 53 focused device tests and check:changed pass.

CcoderabbitaiBot19d ago

@nateEc Thanks for the fix. The updated code derives both platform flags from one fresh SSH probe and updates the host summary. It does not reuse the startup snapshot. The reported regression coverage addresses repeated refreshes after availability changes.

Merged current main in 85facf0e31 and reconciled the device-discovery conflicts. Each refresh reads platform availability once: iOS discovery still includes never-booted simulators, while missing Android SDK warnings keep main's filtering behavior. The test fixture retains dynamic Android availability, including main's newly added SDK-warning coverage. vp run check:changed passes: 54 tests across 4 files, scoped typechecks, lint, formatting, Knip, and GraphQL checks.

Report a failed platform probe as incomplete discovery.

When SshDeviceHost cannot complete probe(config, owner), it returns both platform flags as false. DeviceHubOperations.list then skips xcrun simctl list devices --json and adds no warning to detail. A reachable hub can therefore return its existing inventory while hiding never-booted iOS simulators without reporting incomplete discovery.

✅ Confirmed as addressed by @nateEc

NnateEc14d ago

Confirmed and fixed in ba82af8a328443b3e6f81fa034bd4d4a9c9659fd. A failed SSH platform probe now carries a failure flag into discovery, which returns an incomplete-discovery warning while retaining hub inventory and keeping platform-specific discovery disabled. The existing SSH host test now covers the failed probe and successful refresh clearing the warning; it failed before the fix. vp run check:changed passes with all 54 tests across 4 files and scoped checks.

apps/server/src/device/DeviceHubOperations.ts:151-155 🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Deduplicate simulator IDs across all platforms.

A reachable host can return both Android hub devices and iOS simulators. The hub accepts string IDs without a platform-specific namespace. The current check only rejects an existing iOS device, so an Android device and an iOS simulator with the same ID can both enter devices.

DeviceService.findDevice then matches only hostId and id. It can return the Android device when the caller requests the iOS simulator.

Merged main e455200077ce and completed the integration in ffdce6de7c. Kept main's timeout retention, bounded hub diagnostics, screenshot HTTP error classification and SSH lease cleanup. An incomplete supplemental iOS enumeration now marks iOS incomplete so main's device-retention path can keep the last inventory. Known available platforms avoid another SSH host probe; a missing platform still triggers one shared probe before local enumeration.

Updated the existing device/SSH fixtures to represent the added simctl call and retained both sides' regressions. check:changed passed: 100 tests in five files, three affected-package typechecks, formatting, lint, both knip passes and GraphQL validation. No simulator was booted/reset and no remote host settings were changed.

🟠 High device/DeviceHubOperations.ts:241

A failed or malformed simctl supplement marks iOS incomplete even when /api/devices returned valid simulators, so DeviceService.refresh drops every newly returned iOS entry and can later reject open for a booted device. Because this flag invalidates the entire platform inventory downstream, keep supplementation failures out of incompletePlatforms or merge successful discoveries with cached entries instead of filtering them.

Confirmed and fixed in c70583d066. The whole-platform incomplete marker is now emitted only when no valid iOS device was discovered and enumeration failed. Valid hub/supplement entries therefore reach DeviceService; empty failed listings still retain the old inventory and cannot falsely confirm a post-boot device. Replaced the lower-level failure assertions with service-level cases for command failure, malformed JSON and invalid schema: each reproduced the dropped iPhone before the fix, then verifies it remains listed, opens successfully, and clears the warning on recovery. Also removed the redundant hostId parametrization noted by CodeRabbit; SSH routing remains covered in SshDeviceHost.test.ts. vp run check:changed passes all 99 tests and related checks.

🟠 High device/SshDeviceHost.ts:394

When an Android-only host's refresh probe fails, availablePlatforms returns android: false despite the cached summary reporting Android as available, so DeviceHubOperations.list skips emulator -list-avds and previously visible unbooted AVDs disappear. Because ios is false, the cached result does not bypass the refresh probe; return the cached ios and android values alongside probeFailed instead.

Confirmed and fixed in c70583d066. A failed refresh now returns the cached ios/android availability together with probeFailed, so an Android-only host still enumerates its AVDs. Extended the existing SSH discovery/cache regression through an Android-only failed probe and successful retry; it failed with an empty inventory before the fix. vp run check:changed passes 99 tests across five files and all related checks.

Remove the hostId parametrization from this test.

The test runs twice, once with LOCAL_DEVICE_HOST_ID and once with "ssh-fixture". In makeDeviceHubOperations, hostId is only used to build DeviceBootError in boot. The list path never reads it. Both runs therefore exercise identical code. The "ssh-fixture" case does not test SSH routing, so the title overstates the coverage.

The testing rules say to test at one layer and to avoid repeating a case. The SSH routing path is already covered in SshDeviceHost.test.ts by the simctl mode assertions. Use a single case.

Also change hostId, at Line 71 to hostId: LOCAL_DEVICE_HOST_ID,.

As per path instructions: "Hold changed tests to the rules in docs/internals/testing.md." The testing rules say to avoid duplicate coverage and to flag new tests that repeat a case.

Thanks @nateEc for the earlier investigation and the macOS verification. #28915 by @sreejithraman fixes the same never-booted simulator discovery issue and also verifies that discovery respects the hub’s single-device restriction. Closing this as a duplicate so that work can continue there.
