So I've been developing my app on iOS 11 and 12 for the past few weeks, but after testing on the iOS 10.3.3 iphone 7 simulator (and real iphone 7's), I just realized that the tab bar icons look really stretched for some reason.
They look fine on all phones iOS 11+
I followed the guidelines here: https://developer.apple.com/design/human-interface-guidelines/ios/icons-and-images/custom-icons/
My image sizes are
#3x: 75x75
#2x: 50x50
#1x: 25x25
I've played around in storyboard and have no idea how to fix this. Any thoughts?
Ok, so it turns out I had imbalanced tab bar item insets.
Changing from this:
To this:
ended up fixing the issue. Not really sure why it doesn't work below iOS 11.

I've two live apps on Appstore, my one app is looking quite blurry on iPhone 11(which I just bought) and its fine previous models of iPhone, but my another app looks fine on iPhone 11.
The first app which is blurry is built on xib file and base screen size of iPhon SE and second app which look fine is built on storyboard and base screen size is iPhone 8 but I think that may not be the reason.
Blurry App on iPhone 11 (as it look pixelated)
Blurry App on iPhone 8(as it looks fine and crisp)
Xib file of Blurry App
Let me know why this is happening and whats the solution ? Do I need to revamp all screens in project? Looking for suggestions.
Thanks
Finally I found solution and the culprit was iOS 8.0 and Later check. It was unchecked, which I marked checked and added Splash screens for these defined sizes and my whole apps screens became crisp from pixelated.
I have an app and it works fine on iOS 10 but on iOS 11 the UIBarButtonItems icons shrunk in size. (they are bar button custom item with an image).
I have tried to put them constraints but it didn't work. Any idea?
Thanks in advance]1
I found it!
XCode 9 has some bugs! In XCode 8 it works fine!. It wasn't iOS 11 bug, it's a XCode 9 bug...
regards!
I just recognized that I can see thru the iOS Simulator if an UIView is defined with (semi-) transparent content. But I can not make a screenshot of it, on the screenshot the effect is gone.
The (custom) navigation bar on top has alpha set to CGFloat(0.9).
Here a screenshot taken with an iPhone 6:
Zoom in and you can see thru the simulator window on Xcode. I assume this is a bug, or is it intended behavior of the OS X transparency effects? If it is intended, can I turn it off?
Ok, I have found the problem. Actually it is not a transparency effect but a display problem. I am using an iMac 27inch with an IPS LCD display, which suffers heavily from "screen burning". Xcode is standing on this position for hours so it burned in into the display. That's why I can not make a screenshot - it is a hardware problem.

Yeah this is going to be a hardware / screen problem. Should not translate to your app.
My ios app does not fit on iphone 5 screen. When I run the app, I can see blank space at the top and bottom of the screen. I have made the app compatible for both iphone sizes. But Since I have updated to the latest xcode, I am facing this issue. See screen shot. Can any one please help?
You probably may not have set your Default-568h image.
On the simulator make sure you have set to iPhone (Retina 4-inch).
You can do this by going simulator menu at the top go to Hardware->Device->iPhone (Retina 4-inch) that will change the phone simulator to the iPhone 5 version.

Try setting AutoresizingMask to your container views instead of assigning appFrame.
I have faced the same problem while moving to iOS 7.
Solution comes with AutoresizingMask. iOS 7 has full Screen layout for ViewControllers.
I have an iPad app. When I used it in iOS 5 or 6 its working fine and the UI also seems to be fine. But the same in iOS 7 a black bar on top, bottom, left and right of the screen appeared. Including on the splash screen.
I had tried it by hiding status bar of all views.But I cant fix the issue.
- (BOOL)prefersStatusBarHidden
{
return YES;
}
Can any one know what is the reason?
The same thing happened to me as a result of downloading the latest version of Xcode
and all I had to do was adjust the frame of my view as it was altered during the download. It's so simple I didn't even think to try it.
How big are the bars? Is there any chance this is actually an iPhone retina app and this is iOS 7's new automatic scaling for the iPad's bigger display instead of the old '2x' mode?
Also, does it behave like this in the simulator and if so, can you post simulator shots of it running under iOS 6 and iOS 7?
