ios SDK 4.3 on Xcode 4.2?

I have upgraded to Xcode 4.2 Beta with iOS SDK 5, however, it turned out that the apps built in SDK 5 are no开发者_运维问答t accepted by app store, although the target is set to be 4.0.

Since sdk 4.3 seems to be downloaded with Xcode 4, but I still want to keep the newer Xcode, how can I import SDK 4.3 in Xcode 4.2?

(I tried to reinstall the Xcode 4 with SDK 4.3, but a lot of crashes and errors with no luck. I am also on iTune 10.5.)

You should be able to install Xcode 4.0 (release) in addition to Xcode 4.2 beta.

Try deleting the directories for both, and re-installing...

Since we can't really talk about 4.2 because of the NDA, try asking over at the Apple Developer Forums.

I myself run both 'next to each other'. I have the latest official xCode installed under /Developer and downloaded the latest BETA version which I installed to /Developer/iOSBETA. For updates on old apps I use the official release, archive and release to the AppStore. For new and ongoing projects I use the BETA. This way you have the best of both worlds, in my opinion.
