This EXC_BREAKPOINT crash is something that Swift uses when it wants to crash your app deliberately. The last method name is clearly a mangled name, but it's a pretty good guess that it's a result of your app calling 'fatalError' to crash itself. (It could have been library code, though, rather than a fatalError call you wrote.)Since you're not getting line numbers, that suggests this is a release build of your app, without built-in debug information. In a release build, fatalError doesn't display its error message before crashing.So you have a couple of choices. One is to find the dSYM (debug information) file that Xcode produced when you built the release build for distribution, and symbolicate the crash to find out the last line of your code that executed. Or, investigate the crash using a debug build (reproduce the problem in Xcode, or give a debug build to your tester if you can't reproduce the problem.), and you'll get additional information.
