Question

当我更新firebase pod时出现波纹错误。

无法转换类型'的值（用户？，错误？） - ＆gt; （）'到期望的参数类型'AuthDataResultCallback？' （又名'可选＆lt;（可选，可选） - ＆gt;（）＆gt;'）

    static func signUp(username: String, email: String, User: String, Phone: String ,password: String, imageData: Data, onSuccess: @escaping () -> Void, onError:  @escaping (_ errorMessage: String?) -> Void) {
    Auth.auth().createUser(withEmail: email, password: password, completion: { user, error in
        if error != nil {
            onError(error!.localizedDescription)
            return
        }
        let uid = user?.uid
        let storageRef = Storage.storage().reference(forURL: Config.STORAGE_ROOF_REF).child("profile_image").child(uid!)

        storageRef.putData(imageData, metadata: nil, completion: { (metadata, error) in
            if error != nil {
                return
            }
            let profileImageUrl = metadata?.downloadURL()?.absoluteString

             self.setUserInfomation(profileImageUrl: profileImageUrl!, username: username, Phone: Phone,email: email,User:User, uid: uid!, onSuccess: onSuccess)
        })
    })

}

我怎么能解决这个问题？

Answer 1

只需编写没有类型定义的闭包。

更新代码：

Auth.auth().createUser(withEmail: email, password: password, completion: { user, error in
    ...
}

尝试以下操作：

static func signUp(username: String, email: String, User: String, Phone: String ,password: String, imageData: Data, onSuccess: @escaping () -> Void, onError:  @escaping (_ errorMessage: String?) -> Void) {
Auth.auth().createUser(withEmail: email, password: password, completion: { user, error in
        if error != nil {
            onError(error!.localizedDescription)
            return
        }
        let uid = user?.uid
        let storageRef = Storage.storage().reference(forURL: Config.STORAGE_ROOF_REF).child("profile_image").child(uid!)

        storageRef.putData(imageData, metadata: nil, completion: { (metadata, error) in
            if error != nil {
                return
            }
            let profileImageUrl = metadata?.downloadURL()?.absoluteString

             self.setUserInfomation(profileImageUrl: profileImageUrl!, username: username, Phone: Phone,email: email,User:User, uid: uid!, onSuccess: onSuccess)
        })
    })
}

无法转换类型'的值（用户？，错误？） - ＆gt; （）'到期望的参数类型'AuthDataResultCallback？'
