XCode 15.3 — flipper crushes the build

[kuzkokov]

Description

When using the latest XCode version the build crashes trying to build FlipperKit.
XCode 15.2 works fine.
Unfortunately, can't attach the reproducer since github actions don't have XCode 15.3 support yet.

Steps to reproduce

1. Initialise the app from the template with RN 0.71.17
2. Run the iOS build on XCode 15.3

React Native Version

0.71.17

Affected Platforms

Other (please specify)

When using the latest XCode version the build crashes trying to build FlipperKit.

Is there anything preventing you from removing Flipper?

[kuzkokov]

@cortinico wdym? it comes with the RN out of the box, isn't it?

We're removing it in 0.74. You can disable it from your build if you're not using it and it's making your build harder to maintain. There is an option in the Podfile to do so

well, okay.
it's actually not a problem for me to use XCode 15.2 f.e. as well, but what you are saying is that RN < 0.74 isn't going to support latest XCode out of the box. is it okay for the RN team?

You can just apply the fix to flipperkit, please see facebook/flipper@b3dcdb8

[Bibazavr]

fixed

[Ahsanali012]

@Bibazavr How to fix can you explain

[Bibazavr]

@Ahsanali012 , just update RN to 0.71.18 or 0.72.12

Or you can look into changelog of react native and find out by yourself - which version include fixes for new xcode:)

[Ahsanali012]

@Bibazavr i updated my project to 0.71.18 or 0.72.12 still the issue is same. folly/folly-config.h not found
