Description

Not related to
facebook/react-native#21824
facebook/react-native#23282
as they have older versions of react-native. 59.9 doesn't even have the files they mentions because this repo now handles it.

Since 59.9 and upgrading to xcode 10.2 react-native run-ios always produces an error. I've tried reinstalling simulators and even xcode itself many times now. I've also heard frojm many people that updgrading to xcode 10.2 produces this error as well.

Reproducible Demo

A good repro is completely uninstalling xcode then reinstalling it, start a new project, then you should get the error.

[thymikee]

I'm using Xcode 10.2.1 and never encountered this error. Can you post the full error you get (ideally with --verbose flag passed to the command)?

[thymikee]

Also, make sure you have the latest CLI (so remove @react-native-community/cli from lockfile and run install again)

[d3vhound]

here's with --verbose

Deleted my lock file and reran npm install. This is the top of the @react-native-community/cli/package.json

{
  "_from": "@react-native-community/cli@^1.2.1",
  "_id": "@react-native-community/cli@1.9.7",

So which version do I have? 1.2.1 or 1.9.7?

[thymikee]

You have 1.9.7 now which is good. Still happening?

[d3vhound]

Here's all the sims I have. I may be reaching but do you think it's something to do with 12.2 components not showing up in xcode?

Even though they show up when running xcrun simctl list devices

Yeah issue still exists. Also forgot to mention that building from Xcode works. That's why iPhone XR is booted in the cli output above. Just weird that the cli broke down on me. Another repro could be to download the new xcode beta. I regret doing it now but that could be the root cause

[thymikee]

Oh, that's weird, because your envinfo shows Xcode: 10.2.1/10E1001 - /usr/bin/xcodebuild.

Then you may hit this: #414 (will make a release soon)

[d3vhound]

Yeah I've uninstalled the beta and wiped all the related xcode files before reinstalling 10.2. Just weird that the issue still exists when last week I had downloaded xcode 10.2 and everything was fine.

[thymikee]

Can you try if applying that diff in your node_modules helps?

[d3vhound]

That pull request makes sense though and might be the solution. Do we know what causes it to persist in my case though? I do remember when I tried to delete xcode files following this forum post (https://forums.developer.apple.com/thread/110227) I couldn't and maybe the "issue" got persisted on to my machine

Couldn't delete these with sudo
/System/Library/Receipts/com.apple.pkg.XcodeExtensionSupport.bom
/System/Library/Receipts/com.apple.pkg.XcodeExtensionSupport.plist
/System/Library/Receipts/com.apple.pkg.XcodeSystemResources.bom
/System/Library/Receipts/com.apple.pkg.XcodeSystemResources.plist

[thymikee]

You could probably delete them (if you're sure about that) in Safe Mode. Apple prevents deleting some of the files in regular mode

[d3vhound]

That diff is the solution. Works now.

[thymikee]

Thanks! I'll close the issue then
