+1 ```go type message struct { crc uint16 } msg := &message{} unpack(b, msg) func unpack(b []byte, msg interface{}) error { buf := bytes.NewBuffer(b) typ := reflect2.TypeOf(msg) structType := typ.(*reflect2.UnsafeStructType)...

I fingure it out, it should be `reflect2.TypeOfPtr(msg).Elem()`

let a = [1, 2, 3] a[4] 并不可以

@zixun 我直接把你的Example里的 ``` let arr = NSArray() arr[10] ``` 改为 ``` let a = [1, 2, 3] a[4] ```

@gaoyuexit 真的吗？求分享，我signal试过不行

@gaoyuexit 那也就SIGTRAP能用啊 只能抓到 a non-optional type with a nil value a failed forced type conversion
