Hi Chand,
I think the issue you’re seeing now is that an .app file can be built for a real device or a simulator (these have different architectures - arm vs. x86, respectively). In order to run the test on your simulator, your dev will need to build the .app file while selecting a simulator instead of a real device.
Alternatively, your developer may be able to build the app by setting “Build Active Architecture Only” to “No”.
To verify which architectures an .app is built for, you can run:
lipo -info path/to/MyApp.app/MyApp
