My question is: How to debug this issue? Does ionic2 supports iOS8 and iOS8.1? How to make the app compatible with 8 and 8.1?

Did you get an aswer? I have the same problem with a simple Ionic2 application on iOS 8.4.1 which works on Android.

Nope, I created an issue on github. The team suggested to upgrade to new ionic version. Are you still facing this issue? Which version of ionic are you using?

It was some missing libs as I can remember. I had to test it on osx safari and the same screen was shown but with errors on the web console.
