[BUG] Issue with call.hangUp(options: nil) Triggering Thread Performance Checker Warning #1832

Open ShawnHuangS opened 4 months ago

ShawnHuangS commented 4 months ago

Describe the bug When I call call.hangUp(options: nil), I always get the following warning:

Thread Performance Checker: Thread running at User-initiated quality-of-service class waiting on a thread without a QoS class specified (base priority 31). Investigate ways to avoid priority inversions.

Sometimes this causes my screen to freeze for several seconds, almost like a system crash.

Exception or Stack Trace

To Reproduce

  1. Call the method call.hangUp(options: nil).
  2. Observe the Thread Performance Checker warning.
  3. Notice that the screen might freeze for several seconds.

Code Snippet

self.call?.hangUp(options: nil) { error in
    if let error = error {
        DDLog("Failed to hang up: \(error.localizedDescription)")
    } else {
        DDLog("Call ended successfully")
    }
    self.deviceManager = nil
    self.call?.delegate = nil
    self.call = nil
    completion?()
}

Expected behavior I expected that calling call.hangUp(options: nil) would hang up the call without triggering any warnings or causing the screen to freeze.

Additional context I am using CallKit.

Setup (please complete the following information):

Thanks in advance for your help!

@raosanat can you take a look?

lucianopa-msft commented 1 month ago

Hey @ShawnHuangS, Sorry we took a long time to respond, if there is still an issue, do you mind trying with 2.13.0 version of SDK to verify if issue has been fixed? Thanks

ShawnHuangS commented 1 month ago

Hey @lucianopa-msft ,

Thanks for getting back to me! I also had to update the SDK due to the Xcode update. I’ll test the new SDK with the next app version, or we can close this issue for now since we won’t be using version 2.9.0 anymore.

Thanks again!

Hi @ShawnHuangS, Let's leave this open up until you are able to verify, if issue still persists we have to need this open for tracking Let us know about the results once you verify :)
