I've been away from Xcode for a while, so I may have missed changes in the latest couple of releases. The layout of views looks identical in the Storyboard, and on the simulators (iPhone6 and iPhone7), but different on my iPhone 6. I have no warnings or errors in the Storyboard, and I am using Xcode 8. The device acts as if it had a shorter screen than the simulator -- things that are spread appropriately on the storyboard or simulator, are squeezed together vertically on my phone. What is the reason for this difference?
Have you assigned launch images with the correct dimensions for the different form factors? An easy way to verify this is to add a print statement in a view controller to see what the bounds are for the screen. Verify that these values match what you expect for the device.
The following from Apple documents this:
Because device screen sizes vary, launch screen sizes vary too. To
accommodate this, you can provide a launch screen as an Xcode
storyboard or as a set of static images for the devices your app
supports. Using an Xcode storyboard is the recommended approach, as
storyboards are flexible and adaptable.
While not an official Apple site, this link also references this as a potential issue:
The launch XIB or storyboard is required to support iPhone 6 sized
apps.
Another possibility is that you have the screen zoomed in on the device. To change this, go to Settings > Display & Brightness and select Display Zoom at the bottom. Ensure that you have Standard selected. If you are zoomed in, then the device will scale down (A 6 behaves like an SE, a Plus behaves like a 6/7).

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 something that when you remove the launch screen file entry from the XCode Info.plist file, any view of any view controller becomes scaled according to the screen size, so the views appear zoomed in on large screen sizes such as the iPad Pro (12.9 inches) and appear somehow zoomed out on smaller devices (iPad Pro 9.7 inches).
In that case it seems that the Auto Layout constraints have no effect as the scaling is done automatically.
I really can't understand what does this has to do with the layout constraints, so I appreciate if any one can explain what's the reason for that.
Without being able to provide deep details, iOS uses the launch screen definition (view or static images) to determine which size classes the app should use. If you have not supplied those, it seems you get scaling that you generally do not want.
That doesn't mean auto-layout no longer has any affect... it just means that the auto-layout engine is not using the current screen size for its size/positioning calculations.
You'll see very similar results if you explicitly set your project for iPhone only.
Simple, obvious solution: Don't remove the launch screen.
Yes this is expected behaviour... Same is for iPhone 6 Plus. If you remove the iPhone 6 Plus launch screen, it will display the iPhone 6 scaled version.
This is just for backward compatibility. If your app is not ready for iPad Pro or iPhone 6+, scaled version can be used by removing the respective splashing screens.
All current iPhone apps or iPad apps in AppStore those are not optimised runs as a scaled version.
After trying to create pins to the edges, tops, and bottoms of these buttons, the UI still becomes either stretched or not wide enough when selecting the different devices available from the storyboard in Xcode 8. What can I be doing wrong or how do I correct this issue because Apple won't accept this app due to it not showing in iPhone resolution on the iPad even though this app is set to run on iPhone devices.
Here is an image showing the current constraints:
Here is the demo project where you can find the correct constraints as per your requirement.

I've checked a lot of different websites and stackoverflow answers, and I'm still stuck.
I developed an app for iPhone and iPad targeting iOS 7.1. I have two storyboards, one for each device. The app only displays in portrait mode. I cannot seem to get the app to display full screen on the iPhone 6 simulator.
I've tried numerous things, I followed the advice linked here by adding a Launch Screen, setting the iPhone storyboard to auto layout and "use size classes", and . Not only does that not affect the size, but the Launch Screen doesn't seem to scale properly either. If I get it to fit the iPhone 6 it doesn't fit the iPhone 5 properly.
I've tried adding the proper launch images and I don't get any errors saying the wrong image resolution is present.
I've used the storyboard as a Launch Screen described here.
Now, when I switched to "use size classes" I could manually extend the objects in the views to match up with the size of iPhone 6 (I have not tested it for 6s) but that makes it extend past the iPhone 5 boundaries. The only thing I can think of right now is to create another storyboard and detect if it's iPhone 6, but I would really like some other ideas.
Here's what it looks like for iPhone 6:
And here's what it looks like on iPhone 5:
Best advice i can give u is
Use default size class , the classic 600x600 and then use Auto Layout
Or do the reverse, take a 3.5inch size VC and apply Auto Layout on it. Everything will present itself quite perfectly if you can apply the right constraints
Here is a link for an awesome Autolayout tutorial
When creating a storyboard file in Xcode, you must select if it is for iPhone or iPad. This implies one should always put iPhone and iPad UIs into separate storyboards. Is this true?
My app has multiple storyboards. While the Main.storyboard files largely differ between iPhone and iPad, other storyboards are nearly identical. The only difference might be segue being a push on iPhone vs popover on iPad, which can be handled programmatically. It seems awfully silly and redundant to make two storyboards.
So if making one "universal" storyboard, should iPhone or iPad be selected in Xcode? Does it matter?
As of Xcode 6, we can create a single unified storyboard for all the devices.

iOS 8 makes dealing with screen size and orientation much more
versatile. It is easier than ever to create a single interface for
your app that works well on both iPad and iPhone, adjusting to
orientation changes and different screen sizes as needed. Design apps
with a common interface and then customize them for different size
classes. Adapt your user interface to the strengths of each form
factor. You no longer need to create a specific iPad storyboard;
instead target the appropriate size classes and tune your interface
for the best experience.
There are two types of size classes in iOS 8: regular and compact. A
regular size class denotes either a large amount of screen space, such
as on an iPad, or a commonly adopted paradigm that provides the
illusion of a large amount of screen space, such as scrolling on an
iPhone. Every device is defined by a size class, both vertically and
horizontally. iPad size classes shows the native size classes for the
iPad. With the amount of screen space available, the iPad has a
regular size class in the vertical and horizontal directions in both
portrait and landscape orientations.
Edit:
It only supports iOS 8(backward compatible applies only for iOS 7) and later.
You've got to create to separate storyboards for each kind of device. If you would delete the iPad storyboard, than your app would use the iPhone's one. You'll realize it when you'll see the 2x button at the bottom of the screen. Everything will be scaled to fit the larger screen - and the graphics would be really bad.
The only suitable workaround is to copy-paste everything from your iPhone Storyboard to iPad storyboard. Just follow the next steps:
Open iPhone.storyboard,
Press CMD+A,
Press CMD+C,
Switch to iPad.storyboard,
Press CMD+V,
You'll see, that all the screens, segues, properties and actions are transferred to your new storyboard. All that you have to do is to fix the frames of all your elements so that they'll suit new screen sizes.
And don't forget, that a good iPad application shouldn't be the same as the iPhone version. There are a lot of cool things which you can do with iPad!
