swift5棄用方法'withUnsafeBytes' is deprecated解決辦法

如題，swift5出現以後，這個withUnsafeBytes方法就被棄用了。Xcode提示信息是：

所以，以前的使用方法：

let data = Data()
let value = Int(bigEndian: data.subdata(in: 0..<4).withUnsafeBytes { $0.pointee })

應該改成現在這樣：

let data = Data()
let value = Int(bigEndian: data.subdata(in: 0..<4).withUnsafeBytes { $0.baseAddress!.bindMemory(to: Int.self, capacity: 4).pointee })
