Xcode 13 - iOS 15 error message appears in Xcode console

anko37 commented 3 years ago

[REQUIRED] Step 1: Describe your environment

Xcode version: 13
Firebase SDK version: 8.7.0
Installation method: CocoaPods
Firebase Component: Don´t know

[REQUIRED] Step 2: Describe the problem

Steps to reproduce:

When I bring my App in the foreground or background following error message appears in the Xcode console. Prior iOS 15 this error message wasn't shown. So I don't know if this can be ignored or it will cause a crash on the release version.

Relevant Code:

FirebaseApp.configure()

I found a few problems with this issue:

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
This issue does not seem to follow the issue template. Make sure you provide all the required information.

paulb777 commented 3 years ago

Thanks for the report. Based on https://developer.apple.com/forums/thread/120104, this may be innocuous and may be related to Firebase Performance. Does removing Firebase Performance make a difference?

anko37 commented 3 years ago

Thanks for your reply, I don't use Firebase Performance.

anko37 commented 3 years ago

I have a second app and there it's exactly the same, starting a debug session on a iPhone 7 device and bringing the app into foreground or background shows these warnings.

anko37 commented 3 years ago

On a iPhone 11 I didn't get the warnings.

paulb777 commented 3 years ago

We'll likely need a reproducible example to help here. Since it's a warning from iOS, you might have more luck with resolution asking on an Apple forum.

anko37 commented 3 years ago

This warning only comes when FirebaseApp.configure() is called, if I don't use firebase the warning disappears.

lex910806 commented 3 years ago

I am also having the same problem. This issue occurs when testing on an actual device. (I am using iPhone 12 Pro, iOS 15.0.1)

The app works fine, but I'm worried that the Appstore will process it as a crash.

santieduardo commented 3 years ago

In my project I'm getting these logs too.

My specs: Xcode version: 13 Firebase SDK version: 8.8.0 Installation method: CocoaPods

I am also receiving same errors below in Xcode debug area.

I am experiencing the same problem with Xcode 13.0, iOS 15.0, flutter 2.5.1

paulb777 commented 3 years ago

Thanks for the reports. It would be helpful to get more detail including what Firebase libraries are installed, what package manager is used, and ideally a reproducible example.

Also, there have been similar issues in earlier iOS versions that were spurious logs that had no impact on the apps. Is this problem causing any crashes now? Is it related to slow startup?

我也有同样的问题。在实际设备上进行测试时会出现此问题。（我使用的是 iPhone 12 Pro，iOS 15.0.1）

该应用程序运行良好，但我担心 Appstore 会将其作为崩溃处理。

@lex910806 is build in xcode13?

lex910806 commented 3 years ago

@zeqinjie Yes, I am using Xcode 13. And device is iPhone 12 Pro, iOS 15.0.2. Also I am testing both Swift Package Manager and Cocoapods. The result is still log messages comes out.

@paulb777 said that it could be a spurious error, so I'm going to distribute my app this week.

Same issue here!

ryanwilson commented 3 years ago

Thanks everyone for the report, and sorry for the extra logs you're seeing. It looks like this warning is printed when using a URLSessionUploadTask, even outside of Firebase. I was able to reproduce the issue on my iPhone 12 Pro running 15.0.2 from Xcode 13.0 with a simple SwiftUI application that didn't include Firebase:

struct ContentView: View {
  var body: some View {
    Button("Press me to observe the error") {
      let request = URLRequest(url: URL(string: "https://www.google.com")!)
      let uploadTask = URLSession.shared.uploadTask(with: request, from: Data()) { _, _, _ in
        print("The `nw_has_table_apply` error was logged.")
      }

      uploadTask.resume()
    }
  }
}

Given that it's being logged directly from using Apple's APIs and Firebase functionality doesn't seem affected, I'm going to close this issue. This should be filed as a Feedback/Radar for Apple instead. We can try to do so but likely won't get to it in the next week or two, if someone else wants to file a report and post an openradar link that would be very helpful.

Never saw this error log before and still using Firebase 7.10.0. The only thing I changed is to call ATTrackingManager.requestTrackingAuthorization after applicationState is active. A iOS 15 behavior change.
