Reply to Unable to build project in Xcode 14.3 beta due to missing arc dir at /Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib It is not working for me: Version 14.3 (14E222b)... Pretty annoying, first we receive an iOS update (16.4) which brakes the compatibility with xCode 14.2... Than after updating to version 14.3 RC, still not working but with a different error...
