Indeed that was a simple fix for Xcode 14.3.1 for me however, building the same up on Xcode 15 the NXAuth2Client doesn't work and states that there is a double declaration of the method /APP-PATH/Pods/NXOAuth2Client/Sources/OAuth2Client/NXOAuth2PostBodyPart.m:46:148 Multiple methods named 'contentType' found with mismatched result, parameter type or attributes

cocoa pods need to update a lot of issues . Delete derived Clean build folder pods deintegrate pods install source="$(readlink -f "${source}")" User Script Sandboxing' under the Project's Build Settings > worked for me NXOAuth2.0 Client unfortunately still doesn't work on Xcode 15.

After that issue was fixed I ran into the issue again sporadically alternating with another error Cycle inside MyApp; building could produce unreliable results. As I read from other similar issues that were encountered; it's a bug in Xcode 15. So you build successfully but every now and then you get the failed to emit precompiled header error and sometimes the cycle error. One of the solutions was to move the embedded Pods Frameworks above the compile Sources.
