在 iOS 上注销和登录 firebase 身份验证后，Firestore 调用 setData 将不会进入完成块

Question

在 iOS (swift) 中使用 Firebase SDK

使用 Firebase (4.10.0)

使用 FirebaseAuth (4.4.4)

使用 FirebaseCore (4.0.16)

使用 FirebaseFirestore (0.10.2)

时出现问题

登录（匿名或凭据）
退出
登录
调用FIRDocumentReference.setData然后setData的完成块将永远不会被调用

如果

就不会出现问题

退出
终止应用程序
登录
调用FIRDocumentReference.setData一切正常

import UIKit
import Firebase

class ViewController: UIViewController {

    let mEmail = "tester@xxxxx.com"
    let mPassword = "xxxxx"
    
    override func viewDidLoad() {
        super.viewDidLoad()
    }
    
    @IBAction func clickSignIn(_ sender: Any) {
        print("clickSignIn")
        Auth.auth().signIn(withEmail: mEmail, password: mPassword) { (user, error) in
            print("user:", user ?? "no user")
            print("error:", error ?? "no error")
        }
    }

    @IBAction func clickSignOut(_ sender: Any) {
        print("clickSignOut")
        do {
            try Auth.auth().signOut()
        } catch {
            print("can't signOut")
        }
        print(Auth.auth().currentUser ?? "no user")
    }

    @IBAction func clickSetData(_ sender: Any) {
        print("clickSetData")
        let ref = Firestore.firestore().document("tests/test_1")
        let data = ["text": "xxxxx"]
        ref.setData(data, options: SetOptions.merge()) { (e) in
            if (e == nil) {
                print("setData complete")
            } else {
                print("setData error:", e ?? "no error")
            }
        }
    }

}

有时它也会导致崩溃

经 google 工程师确认，我发现的问题是最新 iOS SDK 版本 (4.10.0) 中的一个已知错误。好消息是，它已经在以下拉取请求中得到修复：890、893。在修复程序公开发布之前，Google 建议我们暂时降级到 4.9.0 版本。目前无法分享任何细节或时间表，因此请密切关注我们的发行说明以了解任何更新。
