We were building our IOS project in Unity using a Mac, and once we checked the Development Build checkbox, the Xcode compilation would fail because it couldn’t find a lot of .h files in the Mono folder. For example: mono/metadata/profiler-private.h, mono/utils the following related stuff! We looked at the project folder and there were no of them. This makes us wonder, why isn’t there any of this in the Xcode project that was built by Unity? As long as we don’t check Development Build, then there will be no such errors and the IOS application will be able to compile normally. (Using Xcode 15, Unity 2021.3.23)
