AIR 28: Unexpected crash on iOS.

Report · Mar 21, 2018

Hi, guys!

Our app is crashing on iOS.

We don't know how to reproduce the crash.

But it happens on user devices (crash reports in XCode).

It seems, the crash is happening inside Adobe Air code.

Are you aware about this issue?

Any tips to solve?

We are building against Air 28.

The app is called YoWindow.

Crash report from XCode Organizer.

Hi,

Can you please provide a sample code where the crash is reproducible so that we can investigate further.

Hi, Pravishti!

Let me quote my post.

"Our app is crashing on iOS.

We don't know how to reproduce the crash.

But it happens on user devices (crash reports in XCode)."

We cannot provide a sample code reproducing the crash.

The app is large.

There's no clue where this crash is happening.

Can you please confirm that the stack trace is originating from AIR?
