Can we run the scene in the unity iphone or do we need an iphone to run the application?
you can’t run it on the mac but you can run it within the editor and use unity remote as input device.
But to really test it performance wise etc you must have an iphone and you naturally also need a iphone developer subscription
hmm, i have already applied for the iphone developer enrollment. So it needs to be completed to test my scenes…
Thank you for the fast response 
definitely get an iphone, app may run totally different than expected on the device, simulator is not enough
