NativeScript
App crashes on iOS if system alert pops up while loading frameworks
From @speigg on February 11, 2016 17:4
May be a little difficult to reproduce due to the nature of the bug.
If a system alert (such as a calendar event alert, or any other number of system alerts, like storage space warning) pops up while a nativescript app has not finished loading (frameworks still loading), the app crashes. This happened while I was attached to the app via XCode. Here is a stack trace (hopefully it's useful):

Fix for this? Having this issue on production app. App asks to allow notifications on load- works in development version but crashes in production.
Hey, @mschahczinski, can you provide the crash log of the app. Also, can you give us some more details about the crash so we can reproduce it on our side.
@jasssonpet - Thanks for the response... Please see attached crash log.
Cliff notes: I was having an issue getting a production version of my app to run. After some time spent pulling my hair out, I could not get the issue resolved. My app would run fine when running in debug, but as soon as I would publish the app and install, it would never fully launch (crashed shortly after splashscreen would appear).
So I thought, maybe it's something with my project. I created a minimal app- tns create fireTest --ng, added the iOS platform and the plugin that I need in my actual app. Again, app runs fine debugging- production version crashes in the same place. Somehow I stumbled upon this issue with the iOS runtime. My curiosity lead me to realize that the plugin that I am using nativescript-plugin-firebase alerts immediately to allow notifications on my device when the app is run.
I am hoping that this issue is what is causing my app crashes, because thanks to all of the time that I have spent debugging the plugin code and my own code, this is the only thing that makes sense. I will also note that it is not a provisioning profile issue (as far as I'm concerned), because if I never initialize the plugin code, the app works fine as a production build- common theme.... It never pops up an alert on launch.
I've created a new app and followed the guide described in nativescript-plugin-firebase but I couldn't reproduce the issue. I will try it later with a different permission.
From the crash log it seems that the application is dying with a JavaScript error (0xDEADDEAD). You can try getting this line out of the #if DEBUG scope: https://github.com/NativeScript/ios-runtime/blob/8021581c64c7cf73fdfde32175eca85d62ac8865/build/project-template/internal/main.m#L34 and watch the system logs for more output.
P.S. Also, when you say that the app is crashing in production, do you mean a local release build or a download from the App Store.
@jasssonpet - If you are trying to do a local release build and running it, it works fine when I do that as well. I am having the issue when I publish the project- tns publish ios OR by archive in xCode using the iOS workspace. This is the only time the application crashes- on those builds.
