In my project I have URLSession.shared.webSocketTask(with: url) to listen to incoming updates from the server. When I hide and open the app again (I guess enter background mode) the socket connection is aborted and I get following errors:
2023-02-17 16:50:58.147335+0100 App[6057:327579] [connection] nw_read_request_report [C2] Receive failed with error "Software caused connection abort"

So it seems like the system drops my socket connections since the file system is not writeable anymore. I already tried some solutions from the internet like:
let config = URLSessionConfiguration.default
config.waitsForConnectivity = true
config.shouldUseExtendedBackgroundIdleMode = true
let session = URLSession(configuration: config, delegate: self, delegateQueue: nil)
but still have the same issue.
Using URLSessionConfiguration.background(withIdentifier: "example") also does not help, it crashes with an error: WebSocket tasks are not supported in background sessions.
I guess the only strait forward solution is just to request a new session after the error occurs. But I believe there is a better setup for that. Does anyone know?
I have been struggling with implementing the Spotify iOS SDK in a simple music player app I’m working on with the intention of learning more about the streaming platform’s API. My app’s features are storyboard-based and have simple functionality (i.e. connect/disconnect, pause/play, fast forward/rewind, fetch album artwork)
I modeled my authorization method off of the demo project SPTLoginSampleAppSwift, and have been trying to troubleshoot the errors I’m getting (I’ll paste them below).
After a few weeks of struggling with this API, I decided to run the demo project on my device and realized that it does not seem to function properly either. Does anyone know how I can fix these errors and successfully initiate Spotify functionality in my app? I’m quite frustrated and would really appreciate any advice. I'm including my repo below as well.

I encountered a weird problem trying to connect with firebase in my project. I already followed all necessary steps - firebase config, cocopod, google.plist - but I keep getting these error messages in this screenshot. Does anyone else encounter this problem and how did you resolve it?

1- I think everything is going well but it's appearing in the error that you may have a poor connection " Could not connect to the server "
My advice is to try it again and make sure from google Plist that it's documented under the same bundle identifier
2- If the previous doesn't work, just try to update the pod
3- In the worst case try to uninstall it & install it again
Steps to reproduce:
Create a new app and call any API to the server to get data
immediately take the app to background
network get disconnects
below is the log:
