When I tried to build app in xcode 11.6, I got this exception and I have no idea where to look for a solution:
Exception NSException * "data parameter is nil" 0x00006000014d7960.
And this is the code that's appear:
DISPATCH_NOESCAPE dispatch_block_t block){ if (DISPATCH_EXPECT(*predicate, ~0l) != ~0l) { dispatch_once(predicate, block); //Exception in this line: Thread 2: Exception: "data parameter is nil" } else { dispatch_compiler_barrier(); } DISPATCH_COMPILER_CAN_ASSUME(*predicate == ~0l);}
