iOs After Launch Screen is loaded black screen - ios

Hey I hope someone can help me.
So far I've only done the User interface of a multiview app, no coding done.
And I wanted to check it in the simulator.
Now, the launch Screen loads correctly, but then the screen goes black instead of showing the first view controller. And nothing in the debugger.
-Edit: After editing the info.plist, I do now get an error in the debugger
regarding to a missing SceneDelegate.
info.plist

You have to set Main Storyboard from Project general tab.

iOS app missing splash screen, new black borders and ui glitching after visualstudio 8.10.10 and xcode 13 update

Just updated to Xcode 13 and Visualstudio Mac to 8.10.10. Since then my app:
Wont display the splash screen.
The app is cropped at top and bottom.
Ui is acting generally weird.
Now I have read old threads on similar problems and adding the Launch screen interface file base name. in the info.plist file does make the app cover the whole screen.
I have tried switching splash screens and change location. But it's just black. I don't use a storyboard for the splash and instead provide several different resolutions, which have worked fine for several years.
The UI is glitching like the loader picture, and several different ui elements where colors are provided are "cut" in the middle showing two colors when it should switch.
I have read the release notes for xcode13 but haven't found anything related that would break the whole UI.
The interface glitching and no splash screen I can't seem to find a solution for. Everything worked fine before the update.
What could be the problem? Some setting in the info.plist, a checkbox in the storyboard?
I'm still new to Xamarin and iOS development and greatly accept suggestions.
Let me know if I can clarify anything.
Thanks

According to your statement, you are not using a storyboard, so you need to replace the Launch Screen with a LaunchImage, then check the LaunchImage file (if it does not exist, you need to create it yourself) and add all strictly standardized pictures inside.

iOS Simulator AND iOS Device showing black screen after running app

I'm having a weird situation here, my simulator and my device show a black screen running the app. However, I do know that the storyboard is imported because the background music I added for the view controller is working, why is my view controller display not loading? It won't work for ANY view controller if I add one in the Storyboard file. Help?
Just made a new project copying everything to it and it works.

iOS Xcode LaunchScreen Storyboard not displaying

I'm trying to use Xcode's LaunchScreen storyboard as my launch screen? All the questions that have previously been asked about this refer back to the old launch image or .xib method - trying to do it now with the new LaunchScreen storyboard that Xcode automatically generates instead. I've selected the LaunchScreen storyboard as my launch screen file in my Deployment Info:
The storyboard itself confirms that it is set as the launch screen in it's file inspector.
And the info.plist file reflects this as well.
And yet, it doesn't work. The LaunchScreen storyboard never shows - it just goes straight to the first screen in my main storyboard. Using Xcode 7.2 and deploying to iOS 9.
Enable these two settings for the LaunchScreen.storyboard
If you are using xcode 11.2 you'll need to remove the app and execute it again to see the launch screen. I have to do this every time I modify the launch screen in order to see the new changes.
Another thing to make sure is that Launch Screen File is set to Launch Screen.storyboard
**Delete the app from the device. Re-run. **
In my case I had all the suggested settings set correctly but continued to have the original blank launchscreen. In the spirit of AmJa's suggestion regarding a "cache" problem, I deleted my app from my device and reinstalled. Reinstalling did the trick for me on both my devices and simulators.
In case anyone else runs into this issue, I resolved it by simply deleting the ViewController on my LaunchScreen storyboard (leaving me with an empty storyboard), creating a new ViewController and resetting the Storyboard entry point to that new ViewController. There may be some sort of bug with XCode 7.2 with respect to the LaunchScreen storyboard and default entry point into the auto-created View Controller, but then again, I've tried replicating this 3 times and it hasn't ever repeated itself, so maybe not.
In storyboard, in ViewController scene, I had to check Is Initial View Controller for storyboard to be seen as Launch Storyboard.
Suprisingly this is not checked when you add first View Controller. Xcode 11.
Just in case it helps someone.
Scenario, I created my new project and copied a old Launch Image from another project. And then started getting the launch image but when I wanted to change it to new image then still i was viewing the old image it was stuck for ever as launch image no matter what I do.
Then I reset my Simulator and restarted my iPhone and there you go I stared getting the new image. This looks like that somewhere in the documents or cache the devices store the old image until you reset the phone.
Thanks
As #abanet, mentioned in his answer, anyone who uses Xcode 11.2 and above, they have to delete their app and launch it again to see launch screen changes. It's not reflecting immediately. It looks like a bug from Xcode definitely not an intension.
How to fix for Xcode 11.0 and above:
Do this: https://stackoverflow.com/a/41287094/2190175 if you haven't already, and after that:
Delete app from device / simulator
Restart device / simulator
Reason: Launch Screen part of storyboard is cached during development and doesn't change until you remove app from device / simulator and reinstall it completely.
Other solutions didn't work for me, but this did:
Toggle on and off Device Orientation (e.g. support Upside Down) and Hide Status Bar in General.
I'm not sure which one did the trick, but it's working now.
If you don't see anything and your Launchscreen.storyboard only has an ImageView in it, then it might actually be showing the storyboard but not the image. Try putting a button in it or something. I've discovered that my Launchscreen.storyboard is actually showing but won't show any images and I don't know why.
The issue can be also that the "LaunchScreen.storyboard" is not added to this target.
To fix this open "LaunchScreen.storyboard" then press on "File Inspector" and under "Target Membership" add it to the needed target.
I tried everything mentioned here, the only thing that worked for me was creating a new LaunchScreen file. I'm using Xcode 12.1
(Don't forget to update the reference in the targets settings)
I was banging my head against a wall with this since Xcode 10.1 does not include a launch option for the new 11" iPad Pro when you create a new iOS Launch Image set, and without it, the iPad Pro doesn't display correctly, leaving me no choice but to get this working with a Launch Screen storyboard.
I tried combinations of so many things, but I wanted to post what ended up making it work 100% of the time (which was, in fact, a combination of a number of things).
As you have no doubt read, for the UIImageView within the Launch Screen storyboard, you should NOT include the extension (.jpg or .png). So many posts say that, but leave out that the reason is that you should create a new image set within Images.xcassets (NOT Launch Screen image set, but just image set) and name it whatever you want (for instance, "Launch-Default"). Then, drag and drop the desired .jpg or .png into the new image set. You will then use the name of that image set within the UIImageView in the storyboard and everything should work fine (the image should even show up inside of Interface Builder).
Also, within the General settings for the project, make sure to set the Launch Screen File to your new storyboard.
You need to add App orientation specific Launch Screen.
LaunchScreen Portrait: https://app.box.com/s/hfoeuvsy68iu913keb8p5hs1z9fdz3jk
LaunchScreen Landscape : https://app.box.com/s/o9q5nkrvk2ewdh57oiiar85zf658olgj
Drag LaunchScreen.storyboard & LaunchScreenBackground.png to Xcode sidebar. Then specify LaunchScreen in Xcode General page. See attach image
In my case, the problem was that the image for the logo was taken from a different target. Make sure that the image is from the main target of the application, and reset the simulator via menu Device/Erase All Content ad Settings...
In my case a few image views cover the whole parent view of the launch screen (e.g. pinned to the view edges). I had to uncheck the Resize view from NIB in the Attribute inspector for the launch storyboard and finally it worked for me (just do not forget to manually delete the old app from the simulator)
In my case the background color of the view (full screen) was set to a "missing" color literal! After trying all above of course ;(
A jpg image does a problem change the extension to png or use another png image
Worked like a charm for me
in xcode9 swift4 LaunchScreen storyboard, use .jpg image & uncheck clear graphics context for imageview. it's absolutly working.

Black screen when launching my app on iPhone

I wanted to disable the launch screen view when app is launched so I deleted the "Launch screen interface file base name" line in the 'Info'.
Since I did it, I get black screen whenever I launch my app.
How can I fix it?
I have found the solution - in General > Main Interface > Main.storyboard.
For some reason it wasn't selected.

Converted Universal App doesn't show the iPad Interface

At the moment I'm building an iPhone App.
Yesterday I tried to convert it to an Universal App.
It worked, but it just shows me the tab bar, but nothing else.
I've created some Web Views and a Table View, but the iPad Simulator didn't show anything, only the tab bar.
The iPhone Simulator works great, I can see all the labels, web views etc...
I've created one Storyboard for iPhone and one for iPad.
I don't know why the iPad Simulator doesn't display anything.
Hope you can help me.
Regards
Check that you have changed the storyboard name in you target general settings, as shown in the picture below.
Use the right name for you app. Check also that the info.plist file for your project has been correctly updated:
(the second entry is for the iPad).
If that is ok, try and make a clean and rebuild.
