Answer 1

這些線是你的崩潰：

Thread 0 name: Dispatch queue: com.apple.main-thread

2 MyApp       0x0000000100030198 0x100024000 + 49560 

的問題是，你的崩潰日誌未symbolicated。您可以使用在構建要提交的存檔時創建的DSYM文件重新進行符號化。如果此DSYM位於Spotlight搜索路徑中，則可以在管理器或設備窗口（將該故障拖放到設備上）或命令行上重新表示符號。

形式蘋果文檔：

跟蹤陷阱[EXC_BREAKPOINT // SIGTRAP]

到異常退出類似，這個例外是爲了給一個 調試器附着在一箇中斷過程的機會具體的 指向它的執行。您可以使用__builtin_trap（）函數從您自己的 代碼中觸發此異常。如果沒有附加調試器，則該過程終止並生成崩潰報告。

SWIFT代碼將終止該程序與此異常的類型，如果它 在運行時檢測到的意外情況，例如：
