Installing iOS 5 for simulator

I've downloaded the iOS 5 beta and want to test my app, b开发者_高级运维ut since I don't want to install this on my iPhone, I'd like it to be only installed on the Simulator. Does anyone know how to do this? In the Xcode Organizer, the software image shows up, but I can't run the app in iOS 5.

You cannot install or update iOS software/firmware for iOS devices on a Mac because of the different computer architecture.

Download and install Xcode 4.2 with the beta iOS SDK, then you can test the app on the iOS Simulator.

You need to install newer version of xcode.

Be careful with Xcode 4.2 .... I believe it's only in preview mode.

You cannot upload apps with preview Xcode

!

1. 1.Partition your MAC, obviously installing OS X on a partition other than the one you use. [ if you can't do it yourself, don't try it]

2. Put Test Xcode and dev stuff in one. The real deal in the other.

That way you can mess about with upcoming cool stuffs.
