I have developing an iPhone application using xcode 4 which is compatible with iOS 4.3 and runs on iPhone 4 device smoothly.
My question is how to check whether my application is compatible with iOS 3 or not.
I do not have any iOS 3 device to run the app so the only solution is to check the compatibility for iOS 3 is simulator but I have not found any option to run the app on iOS 3 simulator.
Any suggestion how to install SDK for iOS 3.
Thanks
Tap the project, tap your target, tap Summary, set your Deployment Target to 3.x. Then the Scheme pulldown in the top of XCode will show you options to run it in the 3.x simulators.
