Hi,I'm working on XCode 8, objective-c language.I have an issue " Apple Mach-O Linker (Id) error ld:entry point (_main) undefined. for architecture arm64".It appeared when I removed my "xcdataapp" file. - My build phases are ok (all Link libraries I need and Compile sources have all my ".m" only once) - I tried to remove my derived data and create it again, nothing happen - I tried to turn on/off bitcode, nothing happen - I did not modify my "apple delegate "If you have any ideas! Thank you by advance 🙂
