Unable to run an ipad application [closed]

Answer 1

If you have the source code, your open it in Xcode, compile it, and then run it on the simulator or a device registered to your developer account.

But, source code doesn't have a .app extension - so I doubt that is what you have.

Answer 2

You simply can't run App Store-applications on the Simulator.
The iOS Simulator is intended for developers: you can only run apps of which you have the source on the simulator. The App Store binary is compiled for ARM while the simulator expects an Intel-build. The only way to get it run is compiling it for Intel which is impossible without the source code.

Answer 3

You can't run it on simulator.
