I used XCode version 7.2.1 for my project. But I updated the XCode version 8.0 now. Though the scroll view is messed in view controllers of my project. Here I have used Resizing only not an Auto layout. I referred many forums. But can't able to find a solution for that. Here I have attached similar links to what I had tried.
Xcode 8 GM seed Storyboard layout issue
Layout issues after updating to Xcode 8
I have to update frame of everything in storyboard every time I start Xcode
What is the exact solution for Scroll view resizing issue in XCode version 8.0?
Its work for me
https://stackoverflow.com/a/39770664/6619234 you can try this...
after Save & Close don't open this xib/Storyboard....it is an temporary solution....till the apple fix it..
Apple just came out with XCode 8.2, which fixes this problem for me. I have been using XCode 7.3.1 for my interface design parallel to 8.1, but I can now use 8.2 without any problems.
The storyboard gets updated with widths and height of frames though, to accommodate the new 'View as:' functionality. Though it doesn't seem to affect running on device/simulator.
Curiously, the bugfix it is not noted in the XCode 8.2 release notes.
I was able to solve the same by selecting my xib files and then I selected my view in the xib after that I went to attribute inspector and changed the size, status bar, top bar and bottom bar as inferred and it worked but before that xocode pointed out I am missing 2x retina display file so I clicked the warning and it was added automatically.
I asked to Apple about this same issue, and they have sent the following message to my inbox:
Hello Raja,
