ShowModal hang/crashes on iOS 15 with iPhone 12 / 13

Recommended Posts

Hello all

 

I got a strange problem with our app.. We use ShowModal (That is supposedly supported by iOS, but even for Android, internally it will use Show because its not supported) to display a form and this has always worked.. Many customers now reported our app will crash on iPhone 12 and 13 with iOS 15.. 


After debugging I found that ShowModal will hang / crash the app, but ONLY on iPhone 12 and iPhone 13 with IOS 15.. If I try on iPhone 11 or 7 for example using iOS 15 (same version, I tried on 15.0.2 and 15.1) it works fine.. Only crashes on iPhone 12 and 13

Did any of you encounter such issue as well?

I solved by not using ShowModal, but only Show,

Fortunately, my wife recently acquired an iPhone 13 that has iOS 15.0.2 on it, and I am seeing the same issue as you: the app hangs. It does not hang on my iPhone X with iOS 15.1.

 

As to why it is just an issue on iPhone 13 (and 12, I guess), I'm looking into it

Thanks Dave. I don't have an iPhone 12 or 13 to test, I was relying on my customers phones (doing testflights) to try to fix the issue

 

It will be interesting to understand why ShowModal only doesn't work on iPhone 12 and 13, while previous like 11 will work just fine with the same OS version

I wasn't able to ascertain what the cause is - I can only suggest filing a report on QP for it.
