Summary

👋, I am working on adding OOT (Out-of-tree) CLI support to react-native-tvos. The update went well, and the OOT will soon have build-, run- , and log- commands for tvos.

However, the wrong simulator is selected.

This bug is unique to the tvos platform. When passing the --simulator parameter, the first device is always chosen, and the simulator parameter is ignored.

tl;dr
The wrong simulator is selected when the platform is tvos.

Test Plan

While the fix is straightforward, testing takes a little setup. I created a sample RNTV project for testing and validating this change.

Pre-requisites
Xcode is installed, and at least two simulators are installed. The trick to reproducing the issue is to select a simulator that is not first in the device list.

In this example, I have two simulators installed and one device connected:
(order from --list-devices)

• Office (18.3)
• Apple TV 4K (17.4)
• Apple TV (17.0)

I will try to run the app on the Apple TV (17.0) simulator.

Step to reproduce

1. gh repo clone cgoldsby/react-native-tvos
2. cd react-native-tvos
3. git checkout oot-tvos-rntester
4. git clean -xdf
5. yarn
6. (cd packages/rn-tester ; bundle i ; bundle exec pod install)
7. (cd packages/rn-tester ; npx react-native run-tvos --scheme RNTester --simulator 'Apple TV (17.0)')

info A dev server is already running for this project on port 8081.
info Found Xcode workspace "RNTesterPods.xcworkspace"
info Launching Office (18.3 (22K557)) // ❌ Wrong simulator is selected. CLI selected first device. Apple TV simulator was expected.
info Building (using "xcodebuild -workspace RNTesterPods.xcworkspace -configuration Debug -scheme RNTester -destination id=2be85da36966f6284f2325c55023e39884a39209")

Expected
info Launching Apple TV (tvOS 17.0)

Actual
info Launching Office (18.3 (22K557))

Testing the FIX
We'll continue and test the fix by rerunning yarn with the patched file.

8. PATCH=true yarn
9. (cd packages/rn-tester ; npx react-native run-tvos --scheme RNTester --simulator 'Apple TV (17.0)')

info A dev server is already running for this project on port 8081.
info Found Xcode workspace "RNTesterPods.xcworkspace"
info Launching Apple TV (tvOS 17.0) // ✅ The correct simulator was selected
info Building (using "xcodebuild -workspace RNTesterPods.xcworkspace -configuration Debug -scheme RNTester -destination id=3D7F6892-1820-48B5-84BF-240D821C8986")

After the patch, the correct simulator, Apple TV (tvOS 17.0), was selected.
