I started to get this peculiar compiler error which I cannot seem to solve. I went through some other posts in internet suggesting fixes, but none of them worked for me. I tried changing the build settings and changed all “self.x”s to “[self x]” as suggested; but didn’t help.
There is multilevel inheritance in my code, (ie game -> board game -> tictactoegame) and im guessing, that structure is the root of problems. The compiler seems to crash at viewcontroller’s line of code just after it synthesizes an instance of tictactoegame named ‘game’.
What is a possible mistake i’m doing? Any help would be appreciated, if you need more info to detect just tell me. This is the error log:

I was using an enum instance imported from the game class header in the viewcontroller, removing it fixed my problem. It compiles without errors now. Struggle for 2 hours, fix it yourself 5mins after posting it in stackoverflow.
