I've been experiencing an issue with CGImageGenerator on the iPhone 11 Pro Max generating images -- it works on the simulator but not on the device. My question is if there are any known issues, my debugging has not revealed anything to me. Thanks!

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'm trying to capture UI Automation script with a sample project. I use Xcode 6 on OS X 10.9.3 and iOS 8 SDK, trying to capture script on iOS 8 simulator, but getting following error:
Script capture is not available on this device
SDK is still in beta, so maybe that's a common bug there. Did anyone else face this bug? Or maybe there's a workaround available?
When I try to do the same things with Xcode 5 / iOS SDK 7.1 everything goes fine.
You should enable UI Automation in the device settings: Settings -> Developer -> Enable UI Automation.
It works for me.
It's a known issue to apple and that they need to fix this which surely they will...

I wonder if I update my primary testing device to iOS8, will this have a negative effect on testing iOS apps compiled with iOS7 SDK on this device? For example bugs related specifically to iOS8, which would not appear on device running iOS7. What problems should I expect?
Ideally, you should have one device to test each operating system version you are targeting. Once you upgrade, you will not be able to catch any issues that relate to iOS7.
I have an iPhone with iOS 8 installed on it, but when I connect it to Xcode 5.1, it doesn't recognize it.
As with the other answers, it seemed fairly random whether or not my iOS 8 device was being picked up by Xcode 5.1. It appears that it works if you have the iOS 8 device plugged in before you start Xcode 5.1. When you do that, you will get a screen indicating the symbols are being processed:
After this completes, the device is selectable. I am pretty sure this needs to be performed with each new beta. That might explain why it appears to suddenly stop working.
If this isn't working for you, make sure you have the latest Xcode 6 Beta to match the iOS 8 Beta version, and connect the device while Xcode 6 is running. The same "Processing Symbol" files process will occur and then Xcode 5.1 seems to work.
the only decent way to make it work is to create a symbolic link to a folder that contains binary for iOS8. You can make fool Xcode 5.1 saying "yes, iOS 8 is ok." via a symlink:
In my case I have Xcode 5.1 on Mavericks HD, and Xcode 6.0 beta 4 on Yosemite HD.
I did:
sudo ln -s /Applications/Xcode6-Beta4.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/8.0\ (12A4331d) /Volumes/MAVERICKS/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/8.0\ (12A4331d)
and Xcode 5.1 did work with my iOS8 iphone.
(note the space before /Volumes/MAVER... )
PS: for every beta, I have to patch again... :(
You need to download the Xcode 6 Beta. It's available in the iOS Developer Center, where you downloaded the iOS 8 Beta.
I have connected my iPhone with iOS 8 installed to Xcode 5.1.First time it doesn't recognize.but when i unplugged device and connect again , Device Recognized.
I dont know the reason Anyway i am sure that you can also connect your IOS8 installed device to Xcode5.1 ....
I've been using Xcode 5 to build on an iOS 8 device just fine. Now all of a sudden, it won't let me anymore.
first use xcode6 build on your iPhone5s.
second open xcode 5 ,unpluge device and connect again.
then device recognized.
Open xcode 6 and wait until device is recognised. When done, close xcode 6 and open xcode 5.1 and your device is going to be automatically recognised.
That way you can run your application on a device with iOS 8 with the old xcode.
I am trying to download applications from my Worklight Application Center Client (5.0.5 version) on an iPhone 5 runnning ios 6.1.2.
9 times out of 10 the download and install of the application will fail, whilst 1 in 10 times it will download and install correctly.
I have also tried using an iPhone running io5.1 and the install works fine. It also works fine on an iPad running ios5.1. It fails on another iPhone running ios6.0
I have checked issues such as signing of the apps and if I am using a correct UDID and I can say that these are not causing the issue, especially when you consider that it works some of them time.
It seems to be something to do with ios6 specifically.
Has anyone else seen this kind of behavior or can offer any help in terms of resolving it?
Thanks in advance,
Joe
The situation with iOS 6 seems better with Worklight 5.0.6, to be released in the near future.
