[Question] Native Crash Reporting Got a segv while executing native code

[Az0th]

Hello Guys,
I get this error when trying ti start the App vie Xamarin Hot Restart on my iPhone. On Android it works.
Is there anyway to gather more information about such an error because I cant really get some useful information from that.
I already tried to find the portion of code that produced that error but it was not successful.

Thank you guys.

@mauroa ?

[stefano-v]

Got the very same problem

[marosbeno]

Me too. It works perfectly fine on iPhone simulator, but crashes on the device.

[Az0th]

I can't really say whether my code would work on an iPhone simulator.
I don't have a Mac or a Remote Buildhost at the moment.
I can only test it via Xamarin Hot Restart on my device.
But I know that it is not related with Xamarin Hot Restart because the Test at Apple for the Testflight Distribution said the same.

[Az0th]

Hello guys,

I got a new Error message in the Build-Output-Console it is in german but I think the important part is in english in bold letters:

Entwicklerimage wird eingebunden...
Der Apple-Dienst "com.apple.mobile.mobile_image_mounter" wird beendet...

Another information:
On my iPad Air 2 it is working.
On my iPhone 11 not.

With Xamarin Hot Restart

[VPRoss]

Getting this "Got a segv while executing native code" situation as well running on iOS with HotRestart. It was working prior to upgrading to Xamarin.Forms 5. Same app works fine against the Android emulator. There have also been iPhone updates in recent weeks so maybe some issue there? iPhone is 11 Pro Max with iOS 14.3

[PKalok]

Keep getting Segv on iOS physical devices, 11 Pro & 12 Pro, Simulator works well. I downgraded Xamarin Forms to 4.8.0.167 but issue still persists. App seems to hang on Launch and die after about 15 seconds

The app has been terminated.

You can just reference Esri.ArcGISRuntime.runtimes.ios v100.11 nuget to just deploy the framework files (this includes no public / .net APIs, but just the framework). That's enough to make things crash. It seems the mere presence of a framework causes this problem.

Repro steps:

1. Create a new blank iOS Xamarin.Forms app
2. Verify that the app runs
3. Add the following nuget package (it's unlisted so might have to do it manually). All this package does is deploy a framework file.

    <PackageReference Include="Esri.ArcGISRuntime.runtimes.iOS">
      <Version>100.11.0</Version>
    </PackageReference>

4. Run application and observe error.

Same issue here.
Works great on simulator.
Crashes when launched on physical device.

Anyone come across a resolution?

[DumaisPower]

I have the same error here. Works fine without awssdk.s3 nuget package. When I add it, app crash at start. If I remove the package, app is back to normal.

nothing new on that ?

2022 seeing this problem as well, did you guys find a solution?
