Ionic app suddenly crashes and closes itself in ios 9


Ionic version:

Current behavior:
Recently I confronted with a problem in my ionic app. This only appears in ios 9 (I didn’t test in other versions of ios). Why I said recently? Since a few days a go, I didn’t have a lot of data in my remote database. No when I load some data with ion-infinite-scroll , and change some states, suddenly app closes with NO ERRORS.

Other information:
I use gapDebug for watching the console log. But no errors appears. Any idea?
