Few workarounds u can try in build settings:
BITCODEGENERATIONMODE = bitcode;
OTHERCFLAGS = "-fembed-bitcode";
OTHERCPLUSPLUSFLAGS = "$(OTHERCFLAGS)";
SKIPINSTALL = YES;
GCCENABLEBUILTINFUNCTIONS = NO;
GCCNOCOMMONBLOCKS = NO;
GCCOPTIMIZATIONLEVEL = 3;
And don't forget to set 'Enable Code Coverage Support' to NO
