APP freezes or closes when deploying to old iPad2 iOS 9.3.5

farukaf commented 3 years ago

Steps to Reproduce

New Xamarin.Forms Project
Template with Shell (others may have the same problem too, I tried with Old Shell and new Flyout)
Plug Device with iOS 9.3.5
Set "Linker Behavior" to "SDKs Only"
Set "Supported Architectures" to "ARMv7 + ARMv7s + ARM64"
Debug

Expected Behavior

Deploy works and APP launch.

Actual Behavior

Deploy works but APP freezes if in debug, closes after few seconds if tapped both not going thru 'splash'.

Debugging stops on LoadApplication(new App()); command at AppDelegate.cs file.

Environment

Microsoft Visual Studio Enterprise 2019 Version 16.8.2 Xamarin Forms Versions 4.8.0.1687, 4.8.0.1534, 4.8.0.1269

Device: iPad 2 Wifi 32gb

Tried different configurations, linker behaviors, and other options I could think. Developer certificate and profile is OK. Device is registred in Apple's website.

This looks like a 32-bit issue, but I'm not able to reproduce it with the devices I have.

Can you still reproduce if:

You change "Supported Architectures" to ARMv7 (only).
You try on a newer iOS device (than iPad 2), but with iOS version 10.3.5 (or earlier).

Also please attach your test solution, just to make sure we're testing exactly the same thing.

With the iPad 2 I tried every combination of architecture, only when ARMv7 (alone or not) the "splash" screen showed up followed by freeze or crash. It's working with an iPhone 6s (don't remember de iOS version).

This is the project I used to make the "sanity check", just to be sure it's not a Nuget or my code crashing. https://github.com/farukaf/XamarinPoC

Soon as possible I'll check the iOS version of the device

I'm not able to physically access to the Mac right now. (remotely working at the moment)

I got the logs from this build and linked as a gist.
