1, 需要用桥接文件 , 不然引用不到依赖库

2, 可以用测试模式测试, 可以debug

3, 测试模式获取deviceToken, 添加测试设备

deviceToken获取方法

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let device = NSData.init(data: deviceToken)

    var deviceId = String()if #available(iOS 13.0, *) {let bytes = [UInt8](deviceToken)for item in bytes {deviceId += String(format: "%02x", item&0x000000FF)}print("iOS 13 deviceToken：\(deviceId)")} else {let device = NSData(data: deviceToken)deviceId = device.description.replacingOccurrences(of:"<", with:"").replacingOccurrences(of:">", with:"").replacingOccurrences(of: " ", with:"")print("我的deviceToken：\(deviceId)")}}
