+
+### 🐛 Bug fixes
+
+- [build-tools] Preapprove custom URL schemes before opening them in iOS Simulator sessions to avoid the first-use confirmation prompt. ([#4274](https://github.com/expo/eas-cli/pull/4274) by [@szdziedzic](https://github.com/szdziedzic))

+- [build-tools] Support an optional `package_version` input on `eas/start_serve_sim_remote_session`, so a simulator session can pin the `@expo/serve-sim` version instead of always running `latest`. ([#4253](https://github.com/expo/eas-cli/pull/4253) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Add composable custom build functions for downloading, installing, and launching application archives in simulator sessions. ([#4222](https://github.com/expo/eas-cli/pull/4222) by [@szdziedzic](https://github.com/szdziedzic))
+- [eas-cli] Add `--build-id`, `--application-archive-url`, and `--expo-go` to `eas simulator` to install and launch an application before the session is ready. ([#4223](https://github.com/expo/eas-cli/pull/4223) by [@szdziedzic](https://github.com/szdziedzic))
+
+### 🐛 Bug fixes
+
+- [build-tools] Upload tvOS (and other non-iOS) IPAs to the App Store Connect platform declared in the bundle's `DTPlatformName`, instead of always uploading to the iOS train. ([#4234](https://github.com/expo/eas-cli/pull/4234) by [@douglowder](https://github.com/douglowder))

+
+### 🛠 Breaking changes
+
+- [eas-cli] Build objects in `--json` output (`eas build`, `eas build:list`, `eas build:view`, `eas build:resign`) now have `app`, `updateChannel` (object with `id` and `name`), and `runtime` (object with `id` and `version`) instead of `project`, `channel`, and `runtimeVersion`. `eas update:republish --json` output likewise has `runtime` instead of `runtimeVersion`. Other update commands' `--json` output and `eas-update-metadata.json` are unchanged. ([#4021](https://github.com/expo/eas-cli/pull/4021) by [@tchayen](https://github.com/tchayen))

 ### 🐛 Bug fixes

+- [eas-cli] Report EAS Simulator as available to Expo admins in `eas simulator:availability`, even when the project account's feature gate is disabled. ([#4181](https://github.com/expo/eas-cli/pull/4181) by [@szdziedzic](https://github.com/szdziedzic))
 - [eas-cli] Make the non-interactive "EAS project not configured" error actionable on every path: list the exact `eas init --id` / `eas init --account` commands and the accounts you can create projects in, instead of suggesting bare `eas init`, which fails the same way. ([#4153](https://github.com/expo/eas-cli/pull/4153) by [@williamgrosset](https://github.com/williamgrosset))
 - [eas-cli] Set up the internal TestFlight group and invite admin testers when submitting interactively with an existing `ascAppId`, with `--no-auto-testflight-setup` to disable it, and fix the TestFlight group URL printed when adding testers partially fails. ([#4136](https://github.com/expo/eas-cli/pull/4136) by [@tchayen](https://github.com/tchayen))

Stanisław Chmiela	97d64f4054	[build-tools] Separate iOS ccache by destination (#4238 ) # Why Looks like ccache cache built for iOS simulator is not helpful for iOS device builds and vice versa. Context: https://exponent-internal.slack.com/archives/C08PBDW7ZC3/p1787242902697509?thread_ts=1787171142.251299&cid=C08PBDW7ZC3 # How Separated `ios-device-ccache-` and `ios-simulator-ccache-` ccaches. # Test Plan - Before: the [simulator build](https://staging.expo.dev/accounts/expo-services/projects/worker-system-tests/builds/5b9eccae-58a7-4a20-919e-61fbbd8ab68d) restored the [device build’s](https://staging.expo.dev/accounts/expo-services/projects/worker-system-tests/builds/026d0b35-0a6d-418d-bf34-488ed68f7d19) cache, got 0 hits, and could not save its own cache because the key already existed. - After: the [device](https://staging.expo.dev/accounts/expo-services/projects/worker-system-tests/builds/02279218-8450-4679-b377-aec998dff0dd) and [simulator](https://staging.expo.dev/accounts/expo-services/projects/worker-system-tests/builds/0e6892fd-a9ee-4a90-ba23-97c7a17ad1e9) builds used separate keys.

Douglas LowderandClaude Opus 4.8	3f8ffac11c	[build-tools] Submit IPAs to the App Store Connect platform from the bundle (#4234 ) eas submit uploaded every IPA to the iOS train because the build upload hardcoded platform 'IOS', so tvOS binaries were validated against iOS rules and rejected (ITMS-90508/90545/90713/90039), and their build numbers collided with the iOS train. Read DTPlatformName from the IPA in upload_to_asc, map it to the App Store Connect platform (appletvos -> TV_OS, macosx -> MAC_OS, xros -> VISION_OS, otherwise IOS), and pass it to createBuildUploadAsync and the TestFlight URL. This also makes the duplicate-build-number precheck run against the correct platform train. Falls back to IOS when the platform cannot be read.

Stanisław Chmiela	4b44fecc69	[build-tools] Apply Appium event timings via default capabilities (#4235 ) # Why Appium is able to run multiple sessions against multiple devices through one server. We want all of them to get the same `eventTimings` (which is for session events integration). # How Moved `appium:eventTimings: true` from remote config (which only applies to the one session) to `--default-capabilities` so all sessions get it. # Test Plan - Verified `--default-capabilities` is a valid Appium 3 flag and that requested caps take precedence over it.	2026-08-20 15:58:12 +02:00
Stanisław Chmiela	1c082665e8	[build-tools] Allow running Maestro tests with `maestro-runner` (#4187 ) # Why `maestro-runner` promises to be faster, more reliable alternative to the official Maestro CLI. # How Added support for `EAS_MAESTRO_BACKEND` and/or input to `eas/maestro_tests` which opts in to using `maestro-runner` over `maestro` command. `maestro-runner` doesn't support DADB, but we don't error if both are enabled. `maestro-runner` has slightly different screenshots and JUnit format -- both are handled. It also exposes a nicer JSON file that lets us parse failed flows without having to parse JUnit file. This adds relatively big chunk of code, but it's all guarded by `backend === maestro-runner` so maybe it's not so bad? I considered splitting logic into `MaestroCliUtils` and `MaestroRunnerUtils` and expose similar interfaces from them, but I feel it was too complicated. # Test Plan - Xcode 16 mixed-flow proof: https://staging.expo.dev/accounts/expo-services/projects/workflows-testing/workflows/019fffe8-9bd8-74f9-87b6-d7963ee6d941 - Automatically selected maestro-runner 1.1.15 without a workflow version input. - Attempt 1 ran both mixed flows. - `report.json` selected only `flows/mixed/fail.yml` for attempt 2. - Uploaded the expected failure screenshot, merged JUnit report, and complete results archive. - Android runner success: https://staging.expo.dev/accounts/expo-services/projects/workflows-testing/workflows/019ffcff-4dcb-724f-8671-51c5644f49e1 - Android official Maestro success: https://staging.expo.dev/accounts/expo-services/projects/workflows-testing/workflows/019ffcf8-ffb2-7c84-bd60-682ffc4a3e7e - Android mixed expected failure: https://staging.expo.dev/accounts/expo-services/projects/workflows-testing/workflows/019ffcfa-6123-7f50-bbbf-42ab03560617 - iOS runner success on Xcode 26: https://staging.expo.dev/accounts/expo-services/projects/workflows-testing/workflows/019ffd22-da8f-79dc-b9c9-3802c5694f7e - iOS mixed expected failure on Xcode 26: https://staging.expo.dev/accounts/expo-services/projects/workflows-testing/workflows/019ffd1e-5923-7b3b-b5cb-c8329a357e97 - iOS official Maestro success on Xcode 26: https://staging.expo.dev/accounts/expo-services/projects/workflows-testing/workflows/019ffd2b-4b37-7601-b665-a675d39f1cdc - Reusable proof workflows: https://github.com/expo/workflows-testing/pull/11	2026-08-19 18:06:24 +02:00
Stanisław Chmiela	7cec953e9a	[build-tools] Cache Gradle file access time journal with the build cache (#4221 ) # Why It seems the cache is not getting pruned properly. It looks like Gradle uses journal to keep track of accessed files. Since we're not caching it alongside build cache, Gradle defaults all files to "they have been used now". # How When caching Gradle build cache, cache journal too. # Test Plan Verified locally. With `build-cache-1` only kept, everything was retained after cleanup because journal inception was "now". With both `build-cache-1` and `journal-1` kept AND inception timestamp backdated, cache was pruned. Didn't test pruning across multiple days.	2026-08-19 17:41:23 +02:00
Stanisław Chmiela	868178fb37	[eas-cli] Add Appium simulator session support (#4190 ) # Why Now that we support Appium sessions, eas-cli needs to support it too. # How Added spread on GraphQL fetch, special instructions for printing and env file. # Test Plan CI should pass.

Stanisław Chmiela	8439f4fbc9	[eas-cli] Protect simulator environment cleanup (#4200 ) # Why Codex insists we should clean the environment up when stopping the simulator.

Stanisław Chmiela	78644d299f	[build-tools] Add Appium remote simulator sessions (#4189 ) # Why Appium is one of the industry standards when it comes to interacting with local and remote mobile devices. I think it may be nice to add support for it to EAS Simulator. # How Added a new EAS function that installs Appium v3, necessary plugin, starts it and exposes its endpoint through ngrok. The event collection is a bit wonky since we're repeatedly calling Appium endpoint for events, but maybe it's ok. Alternatively we could extend session event collection mechanism to support `getEventsAsync`, but decided not to do that (see [diff](https://github.com/expo/eas-cli/compare/8c1e165899c495981ba6bfd506bcd1444cf0c5e8..25c685b5709f66f28341d7f09cc2999d7b0885be)). # Test Plan Tested manually locally.

Stanisław Chmiela	0e85408741	[build-tools] Soft-stop device run sessions at time limit (#4117 ) ## Why Currently, simulator sessions may end at hard 2h job run time limit (and we also override job run's "max run time seconds" to denote "max device run session run time"). This is bad because when job run exceeds its run time, it gets immediately killed and the worker cannot upload screen recordings. ## How Added `max_duration_seconds` param to remote-session build functions. Added duration abort controller/signal and merged it with the cancel abort signal. Whichever happens first — cancel or abort — is going to cause waiting to stop and upload artifacts and exit cleanly. Linear: https://linear.app/expo/issue/ENG-25528/soft-stop-device-run-sessions-at-time-limit Note: this is going to lower the max run time for device run sessions in https://github.com/expo/universe/pull/29554 cause we need to stop simulator session at 2h – (time it takes to upload stuff). ## Test plan When `max_duration_seconds` is not provided we do not do anything. So, we'll deploy this, add the param and see if things are ok.	2026-08-18 16:47:43 +02:00

Stanisław Chmiela	a3f4136ac8	[build-tools] Select compatible `maestro-runner` version for Xcode (#4193 ) # Why `maestro-runner` 1.1.16+ is not compatible with Xcodes older than 26 because when selecing build target it adds an `arch` filter which older Xcodes don't recognize. # How Made it so we install 1.1.15 for older Xcodes and 1.1.16+ for new Xcodes. # Test Plan - Verified automatic version selection on the Xcode 16.2 staging image without a `maestro_version` input. The worker detected Xcode 16 and installed maestro-runner 1.1.15: https://staging.expo.dev/accounts/expo-services/projects/workflows-testing/workflows/019fffe8-9bd8-74f9-87b6-d7963ee6d941 - Reproduced the unsupported `arch` failure with maestro-runner 1.1.23 on the same image: https://staging.expo.dev/accounts/expo-services/projects/workflows-testing/workflows/019ffd14-cb98-7351-9113-872d01c557ae - Successful run: https://staging.expo.dev/accounts/expo-services/projects/workflows-testing/workflows/019fff26-4055-7ae5-8f64-8c3b9190c380	2026-08-18 11:31:21 +02:00
