如何从watch os swift获取设备id

import WatchKit

class InterfaceController: WKInterfaceController {
    
    override func awake(withContext context: Any?) {
        super.awake(withContext: context)
        
        let device = WKInterfaceDevice.current()
        let deviceID = device.identifier
        
        print("Device ID: \(deviceID)")
    }
    
    // 其他代码...
}
