I have a problem with debugging any app using Xcode 11.3.1.
The app builds very quickly (about 3 seconds), but after that, the device displays a white blank screen for a minute or two. On the Report navigator tab, it says that the app is running and debug is already in process but there are no logs. It happens with any app, even a newly created one.
Tried reproducing it on iPhone XS and iPhone 11 pro with 13.3.1 iOS version (the latest one at the moment) - the result is the same.
After this pause, I can debug the app as nothing happened. This behavior happens only during the debug session (no matter using cable or WiFi). If an app was already installed and launched directly from the phone - everything is fine.

In one project, 'capture view hierarchy' and 'pause program execution' buttons are simply not working. 1 out of 20 times it's showing blank screen saying Unable to capture view hierarchy, but other times no response. Capturing memory graph button is working but it's taking forever to load. I have macbook with M1 chip with Xcode 13.3. Before that I had Xcode 13.3.1, which wasn't working as well. This situation is happening for one project only Tried to reinstall xcode-select, tried with different simulator ios versions, tried to run with Rosetta didn't work as well. For intel chips capturing works fine, it's only issue with M1. Any ideas?
I recently upgraded some Firebase packages in my iOS Xamarin app, and now the thing refuses to work. The app opens (shows a splash screen) and immediately closes without producing an error.
While I want to fix the package problem, I have no clue where to start. I set a breakpoint on the App.xaml.cs constructor, but this never gets hit when I run the iOS version. So my next idea was to read the output like I do on Android.
I've been Googling around for a few hours, and everyone seems to say 'Go to Debug > Open System Log...', but this is absolutely rubbish! The system log seems to show everything except for my app running... (E.g. I run the app in the simulator, reload the system logs, and the freshest thing is from 10 minutes ago...)
I'm at my wits end here. Does anyone know a trick for viewing my app output in the simulator? Even just an exit code would be useful 😥
You could view the logs in these locations:
Mac – ~/Library/Logs/Xamarin/Simulator.Server
Windows – %LOCALAPPDATA%\Xamarin\Logs\Xamarin.Simulator
When using the simulator under Xcode 11.3.1 and iPhones simulating iOS 13.3, the simulation does not behave correctly. It works correctly under simulator iOS 12.1.
I get no messages that I don't also get under the iOS 12.1 simulator launch.
The behavior should be when a user starts the app for the first time, he is redirected to the signin screen. Instead it goes to the main screen (grayed out because there is no data). I can navigate manually to the signin screen and signin normally (device registers and appears on my online server) but the app should start downloading the database required to work. It just sits there (no alertview that would normally launch the download). If I relaunch the app, it again starts at the main screen, however at this point an alertview should appear that no database is present. If I manually try to start the download (in a setup screen within the app), the progress bar that normally appears does not, just a label signifying what database is suppose to download.
All of this works properly on the iOS 12.1 simulator (Xcode 10.1) of the same type (iPhone 8 Plus).
Is this an Xcode 11.3.1 bug or iOS 13.3 problem. I have customers using iOS 13.1 without any problems on actual devices. I am on a new iMac running Catalina, is it possible its a security setting to allow database download?
I was facing the same issue and I move back to Xcode 11.3. Guess it was not a stable update at all.
I'm newer to xcode and have picked up this universal app project from another dev who never could figure out how to fix a bug that was in the code because he said that he could not replicate it.
I have 4 different testing devices and I'm able to get the app to work fine on 3 of the 4. iPad retina, iPhone 4, and iPhone 3 all work. It also works fine in simulator. It's the iPad 2 that has been getting the error.
There is a blank / black screen that appears after the application loads. The default.png file shows during loading and then after that the screen goes blank. There is a looping music file that plays on the main view controller iPad_HomeViewController.m. I can hear this playing so I know the app is running, but the screen is blank and you can't use the app. Sometimes the app loads up perfectly and works correctly and then after a few uses of closing it out and reopening it the blank screen appears again. I've also seen it load the iPad_HomeViewController for just a few seconds so that you can see all the graphics and the navigation buttons and then it goes blank/black. I can usually get the blank screen to go away by closing the app out completely and relaunching or by powering the device off completely and then turning it back on and relaunching.
I'm working with xcode 4.3.3
I have combed through the entire internet looking for this answer , and have found nothing, so I have decided to post.
EQUIPMENT: Mac Mini (2011) , running OSXLion (10.7) , 8gb ram, 500gb hd
XCODE: version 4.2, running IPAD 4.3 and 5.0 simulators
I have developed an Ipad app using the program HYPE (html 5 designer/generator), this program was developed by an APPLE team. I then brought it into Xcode using the PhoneGap template. I had developed this app in a previous version of Xcode (4.0 using MAC osx snow leopard) and was able to transfer everything into Xcode 4.2 (including the phonegap template) successfully.
All was running fine. I launched my app in the app store successfully (Five Element Clinic Book HD - http://itunes.apple.com/us/app/five-element-clinic-book-hd/id495512918?alreadyRedirected=1&ign-mpt=uo%3D2&mt=8)
I noticed some issues I wanted to change (namely the external hosting was not working - my embeded youtube video (iframe) was not working, links to external websites not working and an iframe bringing in a counter script (javascript) also not showing - so I decided to take a look at everything to see if I adding more detailed URLs in the phonegap.plist external hosts area would work.
I didn't even get that far. When I opened Xcode again (after about 2 weeks, so there must have been some kind of API change) - I had a tone of errors that lead me to the information of needing to Convert my files over to Objective C ARC.
So I did this, with no errors or issues. Everything converted seamlessly. All files are showing converted to Objective C ARC.
I CLEANED then reBUILT - with absolutely no errors or warnings - and RAN my app in the IPAD simulator (4.3 and 5.0).
This is what happens. The simulator opens, my app launches, the start up screen shows, the app begins to load the rest of the app and just goes to a WHITE SCREEN. Forever. It goes no where else.
So I have quit the app, restarted the app, deleted the app, tried everything again. Same issue. If I quit the app it just goes to a black screen. I have also restarted Xcode and my computer, ran my disk warriors to fix file permissions, etc.
I still have my old project in my old laptop (Xcode 4.0, MAC OSx Snow Leopard). So I went back there to see if I could just work from the old environment. Nope. Same errors that require me to convert files to Objective C ARC. So I converted with zero issues and zero errors. Cleaned, Built - no errors) and ran the program in the simulators. None of them work, everything loads the start-up screen and goes to a white page.
Does ANYONE know what is going on?
And thank you.
Mine was not a white screen - but a black screen.
In applicationDidFinishLaunching I was using the result of
UIWindow* window = [[UIWindow alloc] initWithFrame:mainBounds];
as a local variable.
Converting to ARC released it.
Instead it needed to be assigned to a property of my app delegate:
#interface MyAppDelegate : NSObject <UIApplicationDelegate> {
UIWindow *mainWindow;
}
