I have created simple IOS app in xamarin studio, which contains only design done in storyboard. I ran it in simulator and i got the output which i have desinged. Now i want it to see that on my Iphone device. And i gone through the procedure in (http://developer.xamarin.com/guides/ios/getting_started/installation/device_provisioning/) by seeing this procedure i have created provisioning profile as in that procedure and even i got that provisioning profile displayed in my Xamarin studio . But when run it i got the error Error: Tool exited with code: 1. Output: bin/iPhone/Ad-Hoc/loginpage.app: object file format unrecognized, invalid, or unsuitable. How to slove this?
