app screen height and width not expanding to fit iphone 6 in xcode 7

Question

Hi i switched to xcode 7 recently, and as usual some starting problems arises when switching to new ides. The screen width and height of my app is still set for iphone 5 when am actually running it on iphone 6. This was not happening in xcode 6 it used to render properly for both phone models.

You can see the tab bar buttons ending little higher than bottom and screen is not expanded completely to the right.

Is there any launch image or any other setting i need to add to make screen size fit for all devices.

I have the following settings in my xcode.

Unchecking "Use Size Classes" option and then coming back and re-checking it again fixes this issue.

1. In the project navigator, select a storyboard or xib file.

2. The file’s contents open in Interface Builder.

3. Choose View > Utilities > Show File Inspector.

4. In the Interface Builder Document section, un-tick the "Use Size      Classes" checkbox.

5. Leave the menu. Come back and tick the "Use Size Classes" checkbox again.
