如何在识别出 faceId 后导航到另一个页面?

How to navigate to another page when faceId identified?

点击按钮时我添加了人脸识别和if true,需要导航到另一个页面。但没有工作。应用程序崩溃。几分钟后导航到下一页,后退按钮不起作用。

 @IBAction func myProfile(_ sender: Any) {
    //    self.performSegue(withIdentifier: "MyProfile", sender: nil)
        let context:LAContext = LAContext()

        if context.canEvaluatePolicy(.deviceOwnerAuthenticationWithBiometrics, error: nil){
            context.evaluatePolicy(LAPolicy.deviceOwnerAuthenticationWithBiometrics, localizedReason: "Need to access with your finger print", reply: {(wasCorrect, error) in
                if wasCorrect{
                    print("correct")
                  self.performSegue(withIdentifier: "MyProfile", sender: nil)
                }else{
                print("incorrect")
                }
                })
        }else{
            print("finger print doesn't support touch id")
        }
    }

错误信息是:

[Animation] +[UIView setAnimationsEnabled:] being called from a background thread. Performing any operation from a background thread on UIView or a subclass is not supported and may result in unexpected and insidious behavior.

evaluatePolicy 的回调在后台队列中运行

DisptachQueue.main.async {
  self.performSegue(withIdentifier: "MyProfile", sender: nil)
}
