@hramos What additional information is needed?

[hramos]

A full log with the error message or just any additional detail you can provide. We don't have a lot to go on here.

[ChaseWPDEV]

Sure thing. Full log of the failed build attached.

I Solved this problem by upgrading my XCode from 8.x to 9.x

Would love a compatibility matrix for RN -> Xcode. Does that exist in some form anywhere? Couldnt track anything down in the release notes.

@duhseekoh I would also love to see this compatibility matrix - upgrading Xcode isn't an option for me right now, so I'm a bit stuck

I had the same issue, except I was in El Capitan. In order to fix the issue and be able to run my apps, I had to update XCode to latest (I was at 8.2). But that was not possible in El Capitan, latest XCode required High Sierra.
So, I updated to High Sierra just today, then tried updating XCode and like it did on El Capitan, it just stuck in endless Wait loop and nothing would update even after leaving it for 5 hours.
So, I got sick and tired of it, I went and uninstalled XCode (drag it to trash), then went to https://developer.apple.com/download/more/ and downloaded latest XCode 9.3.1 xib file.
I unarchived it and dragged XCode app to my Applications in MacBook Pro
Then started XCode to complete installation.

After this, I was able to run my react-native apps again in both iOS and Android.

Here are the details I provided on Stack Overflow https://stackoverflow.com/questions/50477166/attempt-to-update-xcode-ends-in-endless-wait

Hope someone will find this useful

It doesn't because it's not "react-native" related. It's a matter of macOs & XCode versions over which we have no control / no clear dependency with.

As mentioned in some other places/issues, react native is an environment with many moving parts, and we don't have control over many of them (ex. gradle, NDK, cocoapods, etc etc).

The general rule of thumb is to not jump on the latest version of anything if not strictly necessary.

Moreover usually these kind of issue surface / are detected quickly so please keep an eye on open issues before upgrading anything

That said, @dbnex14 solution of installing XCode from the dev website is the safest / more reliable - so @ChaseWPDEV I suggest you follow it and please comment if it doesn't fix it.
