I am in a sticky situation and would appreciate any advice. My app is pretty much complete
but when I am deploying it to my iPhone in release mode, my phone crashes when I try to hide the app. I mean, when you swipe up to go back to the home screen.
I have absolutely no idea what to do right now. it's only happening in release mode and it's giving me no error log while crashing so I don't even know where to look.
I don't know what code to show you guys so here's the whole project I guess:https://github.com/vivaanxr/YU-Food
Feel free to ask me to add any other additional details regarding this. This is my first project and kind of lost with this.
This is not the definitive solution to the problem, but should give you more information about what's happening.
Build to your device using Xcode. Then select Window > Devices & Simulators from the menu. Select your device and open the device's console. You can get additional information by reading the console while as the app crashes. Hopefully that helps!

I had completed a Flutter app, which seems to work well in simulator. I then went on to release the initial version of the app to AppStore Connect and sent it to beta testers via TestFlight and they were able to test it without any issue and sent me some feedback.
I made a few changes to the app based on the feedback (nothing too drastic) and tested it throughly in the simulator which seems to work fine. But now when the users download the app via TestFlight it crashed while opening and I cant seem to fix it no matter what I try. Any help would be really appreciated
So far I have tried,
Followed this article letter to letter
Modify optimisation parameters in Build Settings as mentioned here
Tried this SO answer
Crash report from XCode is not much of use since it is not very readable (as attached in the picture).
Can't yet seem to find any reliable answer, Any help on this would be much appreciated.
I started messing around with react-native. I've built a small application and it seems to work fine (package.json). I can work on it in Debug or Release mode, using the simulator or my iPhone 6S device, and all is well.
This app is just for me so I don't pay for the Apple Developer thing, and I just run the app in Release mode on my device, and it...seems to be fine? I can quit xcode and go places and the app works fine.
After a week or so, it's hard to tell, the app stops loading. It'll display the splash screen for a split second and then it's gone back to the home screen.
I setup Rollbar, but it doesn't catch anything. I look in the Privacy -> Analytics area and don't see anything there either.
I'm not really looking for an answer to my exact problem since various SO questions and other places suggest it's probably something weird and specific. My main problem is I don't know even where to look/how to debug this kind of thing. If I build the app and run it on device again, it'll run fine. I need to try to debug without loading new code, and have no idea how that works on iOS. I've tried poking around at the Debug -> Attach to Process by Name, but the app never gets far enough to do anything with that.
Alternatively, I throw react-native in the garbage and use something that works...
App provisioning with a free developer license (?) is 7 days. See: Why does my free XCode Provisioning Profile only last 7 days?
You can likely verify this by looking at error messages in the console window. Connect your device, and in Xcode go to Window/Devices and Simulators/Open Console, then launch your app.
I have an iPhone app and working fine . But some of(2 or 3) my customers arises a complaint that they are having issue opening the app in the iPhone . They have installed the app and when open the app it just closes out right away. Also tried restarting phone but it still does this.Also tried to delete the app and then reinstall it but this still happens.
Is this any thing i can do in my app to prevent this ? Or how they can solve this problem ?
Is there any more information you could give regarding the nature of the crash? Have you recreated this scenario in Xcode and gotten an error message?
The best I can think to tell you is to look in the app delegate. That is where your app looks first, so there is some kind of uncaught error happening.
Maybe the app is trying to use some piece of data right at launch and it's not there. Maybe you are trying to use something before it is initialized.
Is your app using any 3rd party frameworks right at launch? If so, maybe something changed with the library.
If it is happening on some iPhones and not others, perhaps you are using some framework or function that is not compatible with an older version of iOS.
Perhaps there is something in common among the kind of devices the app crashes on.
Another thought, does your app ask for any permissions? Such as using the user's location. If it does, and there is a spot in your code where you assume you have permission and you don't perhaps that could cause a crash.
Hope this helps.
P.S. just read the comments to your question. They have some good advice. I would try what they are suggesting.
A user has reported that my app suddenly won't launch on their device. They sent me a video, and they launch the app, the launch image screen shows for a split second, but then crashes back to the iOS home screen.
The user tried deleting and reinstalling the app with no benefit.
I use Crashlytics, and am not getting any reports of crashes from them (or any other user- although I've seen them in prior versions so I know it's working correctly). I'm also not seeing any crashes in iTunes connect.
I asked the user to send me any crash reports in the Settings Diagnostics section and they said there are none listed for my app.
I have confirmed that their iOS version is supported by my app. (iOS 8.4).
I'm not sure where to go next, and would appreciate any pointers. Sorry for the vague question but I have posted everything that I know about the situation.
Just wanted to provide some closure on this. The user ended up wiping and restoring their device, and it solved the problem. It seems extreme to me but it was their own suggestion and didn't take them long to do. So I'm not sure what caused this but that's one (albeit brute force) way to fix it.
Newbie here, so apologies if this is stupid question:
Are there any applications or solutions out there that would allow you access to debugging events on an app installed on your iphone? To be clear, this isn't an app I've developed, it's just on my iphone and is used as part of another solution which we are developing. Curious if there's a way to just watch the events on an app to help with debugging process.
Thanks.
If you make an app, and build it with a development release, and development signing, you can select to build+run it on a device. Then, you can use the Xcode debugger to see your logs / errors etc.
Steps:
Plug in iPhone
Start Xcode
Hit Build + run
Watch debugger
Logs are either made by the OS for certain things (NSinconsistency, bad constraints, race conditions in view presentation) or by you with NSLog.
Or did you mean when the app is not tethered to your computer? There are other tools for that - including just plugging the phone back in and downloading the logs off the device.
