错误IOS 10-无法从https://mesu.apple.com/assets/复制资产类型为com.apple.MobileAsset.TextInput.SpellChecker的资产信息

Question

我有一组UITextfield供用户注册。我的应用程序构建成功，但是每当我尝试在电子邮件文本字段中输入@时，它都会在下面显示消息，并导致无法注册用户，无法单击“注册”按钮。有人知道发生了什么吗？以及如何解决此问题？

我以编程方式弄清楚了。我加了

tf.autocorrectionType = .no 

停止拼写检查。

 let emailTextField: UITextField = {
    let tf = UITextField()
    tf.placeholder = "Email Address"
    tf.translatesAutoresizingMaskIntoConstraints = false
    tf.addTarget(self, action: #selector(handleTextInputchange), for: .editingChanged)
    tf.autocorrectionType = .no
    return tf
}()
