我想将UInt16转换为UInt8数组,但收到以下错误消息:

'init'不可用:使用'withMemoryRebound(to:capacity:_)'临时查看内存作为另一种布局兼容类型.

代码:

    let statusByte: UInt8 = UInt8(status)
    let lenghtByte: UInt16 = UInt16(passwordBytes.count)

    var bigEndian = lenghtByte.bigEndian

    let bytePtr = withUnsafePointer(to: &bigEndian) {
        UnsafeBufferPointer<UInt8>(start: UnsafePointer($0), count: MemoryLayout.size(ofValue: bigEndian))
    }
