I have been fighting a bug for a few days now. I have been looking everywhere on a solution to this. I am at my end on what I can do.
Basically, my iOS app is crashing on startup. I am getting a SIGABT fault code with an error: FIXME: ftnptr_arg page trampolines. I will attach a copy of the crash report below. I found some posts that are a little similar to my issue on this site:
Got a SIGABRT while executing native code xamarin.ios
SIGABRT error after last Xamarin.iOS update
Xamarin IOS app crashes with exception: EXC_BAD_ACCESS (SIGABRT)
and on GitHub:https://github.com/mono/mono/issues/9871
I have tried these solutions and they do not work for me. I would also like to add that I am using the Bluetooth on the device. I did add the correct permissions in the Info.plist file. The Bluetooth library that I am using is Plugin.BLE: https://github.com/xabre/xamarin-bluetooth-le
Anyways, the crash is happening on a page that does not access the bluetooth device. It is happening on a log in page (which is the first page that is displayed to the user). I do not think that the issue is related to the bluetooth. Like I said previously, I am pretty much at the end of what I can do. Not sure what is going on. Has anyone else out there ran into the issue?
Additional Note:
I would like to also add that I am able to debug the initialization of the form and step through the code without it crashing. I only have 3 functions. One for initialization, another for when the form appears, and a third for when a button is pressed. I can step through the code on the first 2 functions. After the program executes these two, the app crashes. I know that it is not an issue with my code because the same code runs fine on Android.
Also, I would create a minimalist code to post, however, the app includes a number of pictures and graphics that I think would be too large to post here. And I do not think that the issue is related to the code that I wrote. As said above, the code runs fine on Android.
