ideveloperaz commented 4 years ago

these all are critical issue. we could not use normally simulator and app always crashes due to NSUrlSessionHandler.RemoveNotification () from time to time

Thank you for your feedback!

For us to investigate this further, could you please provide your full build logs, crash reports (if any), test case (to reproduce) and all your version information.

To get full build logs just set the log verbosity to diagnostic at the following locations:

On Visual Studio for Windows you also want to add -v -v -v -v to the mtouch additional arguments by right-clicking the project in the solution explorer and selecting Properties.

Note: this is done automatically on Visual Studio for Mac when the log verbosity is set to diagnostic.

The easiest way to get exact version information:

Then copy/paste the version information (you can use the "Copy Information" button).

We look forward to hearing from you!

I could not reproduce as it happens sporadically ... NSUrlSessionHandler.RemoveNotification crash comes from production app and customers (observed in appcenter) and "NSNotificationCenter.g.cs file not found" during app run in ios simulator during debug mode

Here is one of crashes:

Hello @mandel-macaque and @chamons any updates here?

uwe-neuronation commented 4 years ago

Isn't that a duplicate of #6691 But #6691 didn't made it to the stable release so far, right?

mandel-macaque commented 4 years ago

@uwe-neuronation @ideveloperaz @chamons The fix was created in https://github.com/xamarin/xamarin-macios/commit/b062b4c5b6551be19f27149da31f0652540c3205 which was not back-ported to d16-3 or the Xcode 11 branch, that is the reason it does not work on 13.2.0.42.

Looking at git: git branch --contains b062b4c5b6551be19f27149da31f0652540c3205 -r

Just returns that the commit is present in master and d16-4. The fix will be in d16-4 preview 2, which should be available this week.

@chamons please take a look and decide if a back port is needed/worth it.

mandel-macaque commented 4 years ago

Closing issue, feel free to reopen, @chamons will decide if the back port is required taking into account the planned releases we have.

chamons commented 4 years ago

This will land in our Xcode 11.1 branch, and as @mandel-macaque said d16-4. I don't believe we'll have a service opportunity before Xcode 11.1 lands.

If people are interested, I can post a link to our Xcode 11.1 build once this lands, or you can use the preview later this week as well.

mandel-macaque commented 4 years ago

FYI back port can be found here: https://github.com/xamarin/xamarin-macios/pull/7184

uwe-neuronation commented 4 years ago

Is the fix included in the 13.4.0.2 release? It's based on d16-3, right? So it's not?

rolfbjarne commented 4 years ago

@uwe-neuronation the fix is included in the 13.4.0.2 release.
