Hello,
We have updated our codebase to Xcode 8.3 and to my knowledge that means we are now using Swift 3.1 compiler. Our first release using it - almost no change to code since we release very often - had a huge increase in crashes related to memory all over the codebase. The solution was to turn off all Swift optimizations. This forum thread is related to the problem: https://forums.developer.apple.com/message/219236#219236 I have never debugged an compiler related problem so I'm looking into advice on how to pin point what the problem really is. Why our code works with -Onone but crashes with both -O and -Owholemodule? Any tips would be appreciated. Thanks, Felipe Cypriano
