I'm trying to submit a new application to the AppStore but now Apple requires screenshots for iPhone 4.7-Inch and 5.5-Inch. What is the best method to make these screenshot with the full resolution without the device? Thanks for your help!
In Xcode 6 GM run your app with the iPhone 6 or iPhone 6 Plus in the simulator and then hit cmd-s. This will save a screenshot to your computer.

How to save a screenshot in the simulator:
Make sure Window => Scale is set to 100% in the simulator, else you have the correct device, but end up with the wrong dimensions in the screenshot. – Jos
