这是一个创建于 192 天前的主题，其中的信息可能已经有所发展或是发生改变。
swift 新手
写了一个 1000 多行的代码， 没有用 xcode 开发， 直接 vscode 撸的，
运行时 直接 ./main.swift （代码首行 #!env swift ） 或者 swiftc main.swift -o main.bin ， 然后 ./main.bin 运行
现在程序大体稳定， 但是偶尔会崩溃一下， 崩溃时只是提示 crash 和很少信息， 搞不清楚哪里错误。
也试过 swiftc -g main.swift -o main.bin
然后有 lldb ./main.bin ， 再 run, crash 的时候提示
error: No auto repeat.com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=1, address=0x8)
(lldb) me #0: 0x0000000192db0154 CoreFoundationCFGetTypeID + 100
就不会了。。。
有没有可能像 python 那些，crash 了告诉我是哪行因为什么原因错掉的呢？？
谢谢各位大佬！
