swift - Firebase 数据库身份验证 Swift

Question

我通过 Firebase 实现了身份验证的登录和注册 View 。那么我如何才能对我的数据库进行身份验证？我更改了规则并输入:

{
  "rules": {
    "users": {
      "$uid": {
        ".write": "$uid === auth.uid"
      }
    }
  }
}

我也写了获取用户 UID 的代码，但是我怎么能告诉我的数据库我已经通过身份验证了呢？

PS:我需要 Swift 中的示例。

swift 5 仅用于身份验证，然后使用您自己的代码进行扩展

 let credential = PhoneAuthProvider.provider().credential(
        withVerificationID: FireBaseverficationID,
        verificationCode: "your device code")

 let defaults = UserDefaults(suiteName: "group.Company.AppName")
 let encodedData = NSKeyedArchiver.archivedData(withRootObject: credential)
    defaults?.set(encodedData, forKey: "firebasecredential")

在此之后，在您的扩展文件中解码此默认值并使用凭据进行登录

let decoded = UserDefaults(suiteName: "group.Company.AppName")?.object(forKey: "firebasecredential") as! Data
    let credential = NSKeyedUnarchiver.unarchiveObject(with: decoded) as! PhoneAuthCredential

//MARK: - If user already login with credential
    let userid = Auth.auth().currentUser
    if userid == nil{
        Auth.auth().signInAndRetrieveData(with: credential) { (authResult, error) in
            if error != nil {

                return
            }
            else
            {
                //MARK:- Your desire code After Login
            }
        }
    }else{
        //MARK:- Your desire code if User already Login
    }
