Converting Storyboard from iPhone to iPad

I found out a kind of solution:

1. Duplicate your iPhone-Storyboard and rename it MainStoryboard_iPad.storyboard

2. Close Xcode and then open this file any text editor.

3. Search for targetRuntime="iOS.CocoaTouch"and change it to targetRuntime="iOS.CocoaTouch.iPad"

4. Change the code in the MainStoryboard_iPad.storyboard from:

   <simulatedScreenMetrics key="destination" type="retina4"/> to

   <simulatedScreenMetrics key="destination"/>

5. Now save everything and reopen Xcode. The iPad-Storyboard has the same contents as the iPhone-file but everyting could be disarranged.

This saved me hours – hopefully this will help you
