I'm sorry if this may seem a stupid question, but so far I have only developed Android apps and have no knowledge of iOS development.
I'm working for a company that wants me to test their Android and iOS app which are developed by an external company. The external company provides us test versions for both platforms via HockeyApp.
My question is now, is there a way to run the iOS test versions I receive on a Macbook with the Xcode simulator or do I need to ask the external company for the Xcode project in order to test the app with the Xcode simulator? We mainly want to use the simulator to test the app on different screen sizes/resolutions.
