Ios 升级到Firebase 5并存在身份验证问题。无法转换类型为'；（用户？，错误？）

我刚刚升级了Firebase的播客，但却犯了很多错误。我使用了Firebase文档网页上的文档，因此我能够修复其中的大部分。这个错误我被卡住了，需要一些帮助

以下是我的错误：（我将它们标记为错误1和错误2。）

无法将类型为“（用户？，错误？）->（）”的值转换为预期的参数类型“AuthDataResultCallback？”（也称为“可选（）>”）

“用户”类型的值没有成员“UpdateMail”

这是我的AuthService.Swift代码：（所有相同的Swift代码，只需拆分以显示错误）

错误1

Auth.Auth（）.createUser（带电子邮件：电子邮件，密码：密码， 完成：{（用户：用户？，错误：错误？）在

错误2

Api.User.CURRENT_User.updateEmail（电子邮件，完成：{（错误）在

如果你看一下，你会发现他们改变了一些东西，本质上，他们不再返回用户，而是返回另一个包含用户的对象（）

这意味着您需要更改数据库5的语法

在error1中，您可以尝试以下操作：

static func signUp(username:String, email:String, password: String, imageData:Data, onSuccess: @escaping () -> Void, onError: @escaping (_ errorMessage: String?) -> Void) {
    Auth.auth().createUser(withEmail: email, password: password) { (user , error) in
        if error != nil {
            onError(error!.localizedDescription)
            return
        }
        //Here you have to change the uid 
        let uid = user?.user.uid
        //It should be Storage.storage().reference()
        let storageRef = Storage.storage().reference(forURL: Config.STORAGE_ROOT_REF).child("profile_image").child(uid!)
        //storageRef.put was removed and it's changed be storage.putData 
        storageRef.putData(imageData, metadata: nil, completion: { (metadata, error) in
            if error != nil {
                return
            }
            //downloadURL is changed too, you can read at documents of Firebase to know how to use this
            storageRef.downloadURL(completion: { (url, error) in
                if let error = error { 
                    return
                }else {
                    let profileImageUrl = url!.absoluteString
                    self.setUserInformation(profileImageUrl: profileImageUrl, username: username, email: email, uid: uid!, onSuccess: onSuccess)
                }
            })
        })
    }
}

        Api.User.CURRENT_USER?.updateEmail(to: email, completion: { (error) in
        if error != nil {
            onError(error?.localizedDescription)
        }else {  
            let uid = Api.User.CURRENT_USER?.uid
            //Change here
            let storageRef = Storage.storage().reference(forURL: Config.STORAGE_ROOT_REF).child("profile_image").child(uid!)
            //Change here
            storageRef.putData(imageData, metadata: nil, completion: { (metadata, error) in
                if error != nil {
                    return
                }
                storageRef.downloadURL(completion: { (url, error) in
                    if let error = error {
                        return
                    }else {
                        let profileImageUrl = url!.absoluteString
                        self.updateDatabase(profileImageUrl: profileImageUrl, username: username, email: email, onSuccess: onSuccess, onError: onError)
                    }
                })
            })
        }
    })


static func updateDatabase(profileImageUrl: String, username: String, email: String, onSuccess: @escaping () -> Void, onError: @escaping (_ errorMessage: String?) -> Void) {
    let dict = ["username": username, "username_lowercase": username.lowercased(), "email": email, "profileImageUrl": profileImageUrl]
    Api.User.REF_CURRENT_USER?.updateChildValues(dict, withCompletionBlock: { (error, ref) in
        if error != nil {
            onError(error?.localizedDescription)
        }else {
            onSuccess()
        }
    })
}


static func logOut(onSuccess: @escaping () -> Void, onError: @escaping (_ errorMessage: String?) -> Void) {
    do {
        try Auth.auth().signOut()
        onSuccess()
    }catch let logoutError {
        onError(logoutError.localizedDescription)
    }
}

在error2中，它与error1的错误相同，您可以尝试以下操作：

static func signUp(username:String, email:String, password: String, imageData:Data, onSuccess: @escaping () -> Void, onError: @escaping (_ errorMessage: String?) -> Void) {
    Auth.auth().createUser(withEmail: email, password: password) { (user , error) in
        if error != nil {
            onError(error!.localizedDescription)
            return
        }
        //Here you have to change the uid 
        let uid = user?.user.uid
        //It should be Storage.storage().reference()
        let storageRef = Storage.storage().reference(forURL: Config.STORAGE_ROOT_REF).child("profile_image").child(uid!)
        //storageRef.put was removed and it's changed be storage.putData 
        storageRef.putData(imageData, metadata: nil, completion: { (metadata, error) in
            if error != nil {
                return
            }
            //downloadURL is changed too, you can read at documents of Firebase to know how to use this
            storageRef.downloadURL(completion: { (url, error) in
                if let error = error { 
                    return
                }else {
                    let profileImageUrl = url!.absoluteString
                    self.setUserInformation(profileImageUrl: profileImageUrl, username: username, email: email, uid: uid!, onSuccess: onSuccess)
                }
            })
        })
    }
}

        Api.User.CURRENT_USER?.updateEmail(to: email, completion: { (error) in
        if error != nil {
            onError(error?.localizedDescription)
        }else {  
            let uid = Api.User.CURRENT_USER?.uid
            //Change here
            let storageRef = Storage.storage().reference(forURL: Config.STORAGE_ROOT_REF).child("profile_image").child(uid!)
            //Change here
            storageRef.putData(imageData, metadata: nil, completion: { (metadata, error) in
                if error != nil {
                    return
                }
                storageRef.downloadURL(completion: { (url, error) in
                    if let error = error {
                        return
                    }else {
                        let profileImageUrl = url!.absoluteString
                        self.updateDatabase(profileImageUrl: profileImageUrl, username: username, email: email, onSuccess: onSuccess, onError: onError)
                    }
                })
            })
        }
    })


static func updateDatabase(profileImageUrl: String, username: String, email: String, onSuccess: @escaping () -> Void, onError: @escaping (_ errorMessage: String?) -> Void) {
    let dict = ["username": username, "username_lowercase": username.lowercased(), "email": email, "profileImageUrl": profileImageUrl]
    Api.User.REF_CURRENT_USER?.updateChildValues(dict, withCompletionBlock: { (error, ref) in
        if error != nil {
            onError(error?.localizedDescription)
        }else {
            onSuccess()
        }
    })
}


static func logOut(onSuccess: @escaping () -> Void, onError: @escaping (_ errorMessage: String?) -> Void) {
    do {
        try Auth.auth().signOut()
        onSuccess()
    }catch let logoutError {
        onError(logoutError.localizedDescription)
    }
}

您可以再次阅读Firebase的文档，看看有什么不同

        Api.User.CURRENT_USER?.updateEmail(to: email, completion: { (error) in
        if error != nil {
            onError(error?.localizedDescription)
        }else {  
            let uid = Api.User.CURRENT_USER?.uid
            //Change here
            let storageRef = Storage.storage().reference(forURL: Config.STORAGE_ROOT_REF).child("profile_image").child(uid!)
            //Change here
            storageRef.putData(imageData, metadata: nil, completion: { (metadata, error) in
                if error != nil {
                    return
                }
                storageRef.downloadURL(completion: { (url, error) in
                    if let error = error {
                        return
                    }else {
                        let profileImageUrl = url!.absoluteString
                        self.updateDatabase(profileImageUrl: profileImageUrl, username: username, email: email, onSuccess: onSuccess, onError: onError)
                    }
                })
            })
        }
    })


static func updateDatabase(profileImageUrl: String, username: String, email: String, onSuccess: @escaping () -> Void, onError: @escaping (_ errorMessage: String?) -> Void) {
    let dict = ["username": username, "username_lowercase": username.lowercased(), "email": email, "profileImageUrl": profileImageUrl]
    Api.User.REF_CURRENT_USER?.updateChildValues(dict, withCompletionBlock: { (error, ref) in
        if error != nil {
            onError(error?.localizedDescription)
        }else {
            onSuccess()
        }
    })
}


static func logOut(onSuccess: @escaping () -> Void, onError: @escaping (_ errorMessage: String?) -> Void) {
    do {
        try Auth.auth().signOut()
        onSuccess()
    }catch let logoutError {
        onError(logoutError.localizedDescription)
    }
}
