Description

react-native run-ios fails to find target simulator, even with --simulator 'iPhone 14'. It's using a specifier that isn't listed under available destinations:

I don't know if it's related but I have several Xcode versions installed:

• /Applications/Xcode-14.1.0.app
• /Applications/Xcode-14.2.0.app

Does this happen with 10.2 as well? Anyhow related to npm or node version?

[tido64]

Still happens with 10.2. I tried with Node 16 and npm 8.19.3. No dice.

Okay, so this seems to be the reason:

% xcrun xctrace list devices
== Devices ==
Tommy’s MacBook Pro (2) (00000000-0000-0000-0000-69C2E79AE15B)

== Simulators ==

parseIOSDevicesList thinks that my MacBook is a device. An iPhone would have a UDID of the form 00000000-0000000000000000, i.e. two numbers instead of four. Should we add that check?

[thymikee]

Sounds like this is possibly fixed by #1823. @adamTrz could you backport this to 10.x branch?

FYI, though it should be redundant if #1823 fixes things, this isn't always true. Older iOS devices have a different format of UDID: 0000000000000000000000000000000000000000 (no hyphenation at all)

I specifically noticed this issue since 0.71, even with freshly installed projects. There is an additional info line shown after running react-native run-ios as 'found devices' and it includes my macbook along with ios simulators. However I have a project works on RN 0.70.6 with exactly same node, ruby, bundler versions and it doesn't have such an info line that shows found devices. Of course it works without a problem.

Closing, this one. It's fixed by #1863 🎉
