When I decide iOS simulator should show anything but normal iPhone, something very odd happens.
If e.g. iPad is placed landscape left to right, it places content layout all wrong. This also happens in its own iOS before any apps is run. See screenshots:
Tried to reset content and settings, but still no luck:

So the main problem is a blank screen after Launch.storyboard finishes.
But from the beginning: I wanted to use fullscreen in my game. When I checked "Requires full screen" AND "Launch Screen File" was left empty like on the image,
... the app runs without launch screen (as expected), but I get a scene which is NOT playing as fullscreen, like on the image below, (the status bar is visible, there are also two black bars on either side). In the GameViewController I have: override var prefersStatusBarHidden: Bool { return true },
In info.plist I have:
No matter what I do I do not get full screen without visible status bar.
Now, I change to this:
And... Launch.storyboard shows itself (it has only text, not any large pictures), after this nothing happens, there is only blank screen without any images. I can hear background music, I can even touch the screen and the game runs but I do not see anything. This happens on both my physical devices - iPhone SE 1-st and 2-nd gen. attached to my computer. Interestingly, when I press device's sound level buttons, up or down, .. voila, and I can see everything now, the game scene appears! (full screen without status bar, as I expected).
I tried everything: reinstall app, remove Xcode cache, reboot computer and device - nothing works, all the time blank screen with music. I checked on the simulators - on SE (2) and others everything works fine, the launch.storyboard loads, the game is visible from the beginning. On another physical device, iPhone 12 works fine, also on iPad Pro works fine, (but for a very short time the black screen appears). Maybe it has something with memory, but on the other hand SE 2-nd gen. is rather new device.
Do you have any ideas what could be wrong and how to fix this? I do not want to publish the app until I am 100% sure that it works on all devices without any issues.
Thank you ZAY, but I think I have found the answer after many attempts. When Xcode creates the default Game scene, it creates Main.storyboard that looks like this: .
What I did: instead of default SceneKit View, I added default View, like this:
Everything seems to work now. Do not know why, but it works.
I am trying to fill the screen with a TableView. I've tried pinning 4 edges but it broke when I view it in different devices (iPad Pro, iPhone SE, landscape and portrait orientation). The TableView is messed up for some reasons. It shouldn't be this hard to fill that in. Did I messed up some settings in my Xcode?
If you ran the application on a real device you'll find it as you expect it to be.
And if you opened another file then came back to storyboard you'll find the preview as expected too, I think it's a bug in the UI Builder.
Note: I'm using Xcode Version 8.3.2.
I noticed this with separate html code, but I can repeat the same issue using the following url example of an html web app view, such as would be used in a hybrid app. To make it easiest for someone reading this to reproduce the issue, I will include that url here (I don't need to use that url. I have my own code. But this url does the same thing, so is a good example for someone reading this to examine.)
https://framework7.io/examples/tab-bar
Image: These bottom nav bar items do not respond to touch on iPhone 6s or 6s Plus, but DO work on 5s and SE
To reproduce:
Create a simple iOS App with a wkwebview (you may already have one from a previous project)
Simply ensure the webview loads the above url, and you will be able to observe the issue.
If a wkwebview in a Swift app loads the above url in an iPhone 5s or lower within a full screen wkwebview, the bottom tab menu (with choices for information, inbox, upload, and photos) will work. But if opened in iPhone 6s or 6s Plus, the bottom tab menu will not work. You can tap on choices, and nothing will happen.
Important: This is not in Safari. This happens in the context the link being opened in a wkwebview within a Swift app. This is repeatable.
I have checked the layer debugger, and nothing is in the way of the bottom tab.
Thank you very much.
I was going to just delete this, but you never know. Someone else may have the same question later. Maybe this will help them.
So here is the answer which I have just figured out:
I hadn't added auto constraints to ensure the webview would stay the same size as the window. That is why it worked on the smaller phones like the 5s and SE (because the webview happened to aready be big enough.) Meanwhile, the bigger screens of the 6s and 6s Plus were beyond the size of the webview.
I saw it in storyboard and added constraints to ensure the webview would stretch to however big the screen was, and everything started working. The lower nav bar was no longer out of reach of my taps.
I do think it's odd that the content displayed on the entire screen, but only the area which detected touches did not extend to the screen, but that is an opportunity for me to examine the code and see how things are arranged.
The main issue has been solved.
Getting through some introductory swift and playing with Xcode and I basically just have a page with some color squares, background color etc. Doesn't do anything. Problem is when I compile the code it will run in simulator just fine and show everything perfect, BUT when I rotate the device, everything disappears and it only gives me a blank white screen. Rotating right or left does it. The only view that shows it is the original upright view (for all iPhone devices that I tested on through the simulator).
Xcode 6.1.1 and iOS Simulator 8.1 are being used on my MacBook Air with OSX 10.9.5.
In the App general page, I have already checked under Deployment info that Landscape Right and Left are both checked on. Storyboard is set on Any H and Any W.
I'm not sure what I'm doing wrong and it has been pretty difficult searching since I'm still new to iOS development I'm not sure I'm using the right words or whatever because I can't find an answer.
Summary:
App displays properly in iOS Simulator, Portrait View but no other views work and will display blank white screen instead.
In order to see if your views are actually being drawn and just off screen as others have suggested capture the view hierarchy. Go to 'debug' in the menu, then in 'view debugging' click capture view hierarchy. This will pause your app and create a 3D representation of all view on your screen which you can move around by clicking and dragging.
Are your views actually being drawn? If yes are they drawing off screen? If yes then you need to fix your constraints.
It sounds like you haven't set your constraints appropriately. Try setting the top and leading constraints for each of your views to something less than 320 (should cover all device sizes). Fix your warnings, then try again. I believe the views are simply off the screen.
You don't have the correct auto-layout UIConstraints set in interface builder. Check the document outline view in interface builder and ensure that you have appropriate constraints set on each view.
Auto Layout issues occur when you create conflicting constraints, when you don’t provide enough constraints, or when the final layout contains a set of constraints that are ambiguous.
Check this Apple documentation out, it will show you step by step how to resolve your (common) issue.
I need your help. I have designed an app to target iPhone only and everything works fine. However, I just realised that when I run it on iPad, I get black spaces around the screen (view doesn't cover full screen of the iPad) and strangely, the bottom part of the app gets cut off when it runs on iPad. How do I get full screen iPad mode without part of the view getting cut off. Thanks
This is normal behaviour(black spaces around the screen) if the value for "Devices:" under Target/deploymentInfo is set to iPhone. In this case you can still test on iPad but with iPhone resolution. (but if it set to iPad you can not test on iPhone).
if you want to get iPad resolution you have to change "Devices:" value to universal.
for (bottom cut) check if your code uses device size for positioning buttons.
Your app must also run on iPad without modification as for
2.10 App Store Review Guidelines
At first, you have to set your the view (on Main.storyboad) to fit all size. That is `wAny hAny).
Then selected the views, add some constrains to them one by one. When you run the app, it should be right. If the position doesn't match your expectation, you can change the constrains. You should know things about AutoLayout. Find some article to read, and practise.
Thanks guys for all the comments. Using your comments and reading and testing AutoLayout features, I am able to solve the problem.
