i just opened my existing projects created with Xcode 5 for iOS 7.2.1 in the new Xcode 6 and executed these app on the new iPhone 6 Plus.
The Apps worked so far (except for some corrections due to the Location Manager etc.).
But the Apps view is just scaled to the larger screen. It´s not the native resolution of the 6 Plus.
When i create a new project and add some frame work UI elements like a Button or a TableView, then the native (new) resolution is used.
Which kind of settings has to be changed now to adapt the Storyboards in the existing Apps for the new 6 and 6 Plus screen sizes?
Kind regards
Edit:
I think i found the solution here:
iPhone 6 Plus resolution confusion: Xcode or Apple's website? for development
This is the hint:
Note: Upload LaunchImages otherwise the App will run scaled and not show correct scaling, or screen sizes. In scaling mode the nativeScale and scale will not be the same.
