The implementation was done quite a while ago. Now, that we have support in lldb (swiftlang/llvm-project#773), we can enable it by default in the compiler. LLDB now shows the runtime failure reason, for example: * thread #1, queue = 'com.apple.main-thread', stop reason = Swift runtime failure: arithmetic overflow frame #1: 0x0000000100000f0d a.out`testit(a=127) at trap_message.swift:4 1 2 @inline(never) 3 func testit(_ a: Int8) -> Int8 { -> 4 return a + 1 5 } 6 For details, see swiftlang#25978 rdar://problem/51278690
