I don’t know how much you can help me because its under the NDA, but I recently updated to the OS 4 beta 3 xcode version. My project worked fine under 3.2 but under 4.0 parts are a not quite right I assume because it is still being developed.
Every other installation of the beta sdk I could go into the project settings and select the iPhone 3.2 sdk and then change the target iPhone OS in the top left of Xcode but not this one. If I select 3.2 it still loads on 4.0 it seems I only have the 4.0 simulator and the iPad 3.2 simulator.
Any ideas how to get the 3.2 Simulator back?
It would seem that Apple has not included the older iPhone simulators in the latest beta version of the SDK. There is almost a 1GB dif between the two installations.
There may be a way to add all the old simulator and device SDKs by installing all the packages in the old version of the SDK (the newer one is missing the folder) but after trying to install just the ones I needed with no success I just reinstalled the old Xcode instead which fixed the problem.
