Answer 1

我只是假设您可能在闭包中使用if语句。if语句可以是这样的

@IBAction func logInPressed(_ sender: AnyObject) {
Auth.auth().signIn(withEmail: emailTextfield.text!, password: passwordTextfield.text!) { (user, error) in
if error == nil {
print("Sucessfully loged in!")
self.performSegue(withIdentifier: "goToUserDetailVC", sender: self)
}
else {
print("Cannot log in the user")
}
}
}

在这种方法中，我选择一个电子邮件注册，如果没有错误(error==nil(，它将转到segue引导的位置。

我在第一次尝试时得到了相同的错误代码。然后我意识到我创建的if语句是错误的(error！=nil(。我的代码中的问题以及我为什么会得到失败状态8196是if语句，这就是我解决它的方法。我希望它能帮助其他人。
