6.5 inch screenshots for app store

Hi,

I am about to publish my app but I need a 6.5 inch screenshot and I don’t know how to proceed.

Is it possible to run the app on the xcode simulator?

And, if yes, how can I do this?

Thanks in advance for your replies.

I also needed it and checked Google for a solution. 

⌘ + S or  window + s or  File > Save Screen Shot makes a screenshot of your simulator and saves on Desktop by default.
