I am trying to create an iOS plugin for the Godot game engine which utilises GameKit. For some reason it is struggling to build the required static library when #import <GameKit/GameKit.h> is utilised.
This does not seem to be a specific Godot issue looking through the error log and seems to be a direct issue with the SDK in XCode 15.
Here is an extract from the compilation error for reference (I cannot submit the full error due to forum limitations):
