             After upgrade my xcode from 9.0 to 10.1(iOS SDK12.1), my app will crash when optimization level of xcode set to Fastest, smallest[-0s].If I turn off the optimization option, the program will work properly. I think the reason is the new version llvm. so i want to recompile my program with iOS sdk12.1 and xcode9, but the program cann't be compiled, there are so many errors. so how to solve this problem.
