SwiftCChar元祖转String

iOS有些API是调用C函数，Swift端获得的数据是CChar元祖，需要转成String方便使用，下面的代码以获取手机型号为例

方式一

var systemInfo = utsname() uname(&systemInfo) let deviceModel = withUnsafePointer(to: systemInfo.machine) { tuplePointer in let cCharPointer = unsafeBitCast(tuplePointer, to: UnsafePointer<CChar>.self) let machine = String(utf8String: cCharPointer)! print("machine: \(machine)") return machine }

方式二

var systemInfo = utsname() uname(&systemInfo) let mirror = Mirror(reflecting: systemInfo.machine) let arr = mirror.children.map { $0.value as! CChar } let machine = String(cString: arr)
