I have an app which has started freezing at random when I run it on the iPad. It does not happen on any iPhone, not yet anyway. I download a bunch of images on my app, to display on a list, and store them to the internal cache in the background. Also, the app uses modal segues. The freeze is so random I am not able to pinpoint the source of the problem.
All this has started after the device was upgraded to iOS 7. I have also upgraded my Xcode to version 5 and am using iOS SDK 7. Everything was working fine on iOS 6.
Has anyone been facing similar problems?

Anyone noticed issues with apps that are created with Xcode 9 and do not seem to work on iOS 9.5.3 and in this case an older iPad 2?
I have a customer that downloaded my app that I’ve complied and uploaded with Xcode 9, but when he installs the app it crashes straight away, and on some occasions in a flash of 2 sec. will display the interface builder screen layout of the app (ie all the views, buttons etc that are visible on interface builder but with a normal app nicely hidden until needed etc).
The minimum development target in Xcode is set to 8.2 so I assume it will and should be backwards compatible?
Seems like the device is jailbroken.. My latest app version includes a check for a jailbroken device, and does not allow the app to load when it detects one.
I Could reproduce the exact behaviour when triggering this validation check.
I have updated an iPhone App which was workig perfectly in previously .
But now after updating Apple has rejected with following issue.
Performance - 2.4.1
We noticed that your app did not run at iPhone resolution when
reviewed on iPad running iOS 10.1.1. Specifically, the app loads to a
white screen and does not displays properly on iPad.
We've attached screenshot(s) for your reference.
I have checked in simulator 10.0 everything looks good .
But i don't have Xcode 8.1 so i can not able to reproduce the issue.
Does any one has any idea about the issue.
You should test your app on real device because in some cases some kind of storage techniques work on simulators not on devices.
I am developing app for iPad with greater than 7.0 version.
I am facing annoying issue regarding UI. When I run app in iOS version with 7.1 it display as below:
I can access the buttons, textfield and all, but can't get background image, button background images of any controls.
I also run in simulator and same problem I get in it, but after reset the simulator, it's running fine. Now the question is, what about device?
When I run same app in different device with different iOS version like 8.0 and above. It's running perfectly.
I have an application build on Xcode 4.6 and iOS 6.1, but now apple requirement of submitting app must be published using Xcode 5.0. I set the deployment target to 6.1 in Xcode 5 and publish the app to app store.
I have a plan to shift completely to ios7 later but when I run app from Xcode 5 I am getting old UI but if i am downloading from store I am getting the ios7 UI which is not optimised and all loping very bad.
How to fix this issue?
Some UI elements are iOS version depended (no matter on what Xcode version your app was compiled). If you are using iOS 7 (on the simulator or on a real device) your UIAlertView for example will have the new iOS 7 UI. (Blurred white with blue writing)
I'm guessing that your iPhone has iOS 7 on it while you are trying to run your app from Xcode on iOS 6 simulator.
On a device running iOS 7, all of the system UI—such as alerts and
notifications—uses the iOS 7 appearance, even if your app is currently
using an earlier appearance.

If you want to keep the legacy UI and still use Xcode 5 you can read this great tutorial.
I'd still advise against this, staying behind will stack more and more problems that you'll need to solve eventually.
I have some strange problems of memory management on iOS 5.1.1, I'm NOT using Automatic Reference Counting in the project. Everything works well on iPad 3 5.1 or other devices with 5.1 or lower, this issue happens to two different project (one game and one app). So I think I have coded the right retain/release stuff.
Generally some Objective-C objects are released before it should be. When access it later, app crash. This happens on an iPad 3 LTE, an iPad 3 Wifi and an iPod Touch 4, all running iOS 5.1.1. It never happened on any device running iOS 5.1 or lower. I haven't found any pattern for this. Sometimes even an UIView which is still one the screen get released, if user touches a button, app crashes.
I understand these kind of issue can be debugged with NSZombies. But when I enable NSZombies, this kind of problem never happened.
It looks like a bug of iOS 5.1.1 to me, I'm wondering if it can be fixed on app side.
