We have an iOS native app developed with Objective C and using auto-layout with Storyboard for UIs.
It is working fine in iOS 12.4.1 in all devices and it is not
working now in the iOS 13 on iPhone 6s/7/8 only.
Only this screen size has the issue.
Other than that all other iphone screens are supporting upto to
iPhone 11 Pro Max.
And this issue is not there in the iPhone 6s/7/8 simulators. Only in
the real device.
When it is installed on iPhone 7 and run the app it lags very much
and freeze the app occasionally, I have to close it, But the iphone is also gets laggy.
I am not getting any errors.
I thought this is layout issue, so I've Removed constraints of all first showing screens and re-added the constraints. And tried to debug with XCode Instruments to test performance but that didnt show me any issue also(I am not much familiar with using XCode Instruments).
I am stuck with this issue for several days.
And I couldnt find anyone having the same issue.
I appreciate any help regarding this.
What could cause this?
I was facing a similar issue and found out that SearchDisplayController which is deprecated, was being used in the code and storyboard as well. That was causing my app to crash on real device, but not on simulator with iOS 13.1.2. After removing the SearchDisplayController, things worked fine for me.

I am developing a ReactNative app for iOS using Expo.
The app worked correctly on a real iPhone with just basic components (View, Text, Button & Styling).
However, I added Stack Navigation last night. The app had no issues on the simulator so I built through 'eas build' (also no problems). I submitted it to TestFlight for internal testing. But, when I click to open the app, it crashes immediately. As it is an actual app, it gives no info about the cause.
I am very stumped, so any help would be great. Thanks!
Solved this months ago but forgot to post the solution.
In case anyone is having a similair issue, the problem was really small.
I was using navigation components such as'createStackNavigator' instead of their native counterparts e.g. 'createNativeStackNavigator'. Made the swap and the app is now working properly.
I saw the resolution questions:
iOS simulator for iPhone 5- 1136 x 640 resolution
I have done
react-native run-ios --simulator 'iPad Pro (9.7 inch)'
I even went to "Hardware" menu and selected the device again.
My app launches in dimensions of tablet, however the contents within are not rightly sized, it is hugely zoomed. I fixed this accidentally before but I cannot figure it out now. Here is a screenshot of my situation:
It seems like you are running a zoomed in iPhone app (which is possible to do on iPad, so the simulator does what it's supposed to do). You need to set the app from iPhone to Universal in Xcode to tell it that your app is targeted for iPad as well.
I do a Titanium application that woks on iOS and android. Now, I want to create the Blackberry version.
I've tried with a simple app and it's launched well at simulator, but when I've tried my app it doesn't work.
It launches splash screen and begins to load the elements, but I think the app crash because simulator returns to main screen, there isn't any alert (like on android when app stop unexpectedly), it only returns to main screen.
My problem is that I don't know what happen and I can't find any error logs...
I connect by telnet to the simulator, and there I can see the first traces of my app, but any error.
Do you know what can be happened? How can I know if I have an error? How can I know if my app has crashed?
Sorry, if it's an easy question, I'm newbie at Blackberry.
I'm using Titanium SDK 3.2.2 and Blackberry SDK 10.02
Thank you very much
I've created a new project (with Titanium SDK 3.1.3 instead of Titanium SDK 3.2.2) and copy all files there. I've tried to launch the app many times, and one of them, the app launches.
Maybe it was a computer or simulator problem.
I have created a Sencha Touch 2.3 app and tried to build it on iPhone5 using xcode. Sometimes when I deploy it, the phone freezes and then the only choice left is to force a reboot.
This happens occasionally only while trying to build it.
Has anyone else come across this ?
At first, I assumed it happens once in a while only while trying to build and deploy it.
But recently, someone reported a similar issue with another sencha app on an iPhone5 which was already downloaded and used several times. While launching this app, the screen went white and after a while the phone rebooted !
Is Sencha Touch apps causing this ?
Just want to make sure if this is just me. My app when running on the iOS6 simulator or a iOS6 device is serving iAds just fine. The same app running on the iOS7 Simulator or devices never serves ads.
** Failed to receive ad - The operation couldn’t be completed. Unknown error
If it makes you feel better, I'm getting this too. Works in iOS 6 simulator, but I get the error in the iOS 7 simulator and my iOS 7 device. I'm hoping this is just a problem with debug mode and not a problem when the app is deployed.
As of today Apple seems to have fixed it.
