• 获取序列号(Serial Number)

if let sn = Device.serialNumber() {
  print("serial number: \(sn)")
}

• 获取设备型号(Model Identifier)

if let model = Device.model() {
  print("model name: \(model)")
}

• 获取产品型号全称(Full marketing name)

 Task.init {
    if let pn = await try? Device.marketingProductName() {
        print("product name: \(pn)")
      }
  }
