My application debugs fine on the iOS simulator, and it runs fine when I build and deploy an ipa file to the device. However, if I try to debug on the device (iPhone 9.3.1 and iPad 9.3), the app immediately crashes on startup. I am using Visual Studio w/ Xamarin. The problem seems to be build/configuration/version related since it works fine on the simulator and IPA file versions, but I just cannot figure out the problem.
Visual Studio 2013 Update 5 Xamarin 4.0.3.214 Xamarin.iOS 9.6.1.8

To fix Android apps that keep crashing: To do this, go to Settings and open Apps. Under Your apps, you'll see a list of the apps currently installed on your device. From the list, tap the app that keeps crashing and tap Force stop in the bottom right corner. Then try opening the app again.
Select an app. On the left menu, select Quality > Android vitals > Crashes and ANRs. Near the center of your screen, use the filters to help you find and diagnose issues. Alternatively, select a cluster to get more details about a specific crash or ANR error.
You can use try/catch blocks, then send details on the Exception in your catch . Show activity on this post. There are implement UncaughtExceptionHandler as mentioned in these answers and write crash report in some file or use it another way. Show activity on this post.
I am replying on the basis of native app , this can happen if you set Adhoc Provisional Profile to the Debug option in build settings of project. This means for debugging your code you need to set debugging provisional profile for 'Debug' not adhoc type provisional profile.
