I have an iOS project that I've put in Dropbox to work with a few friends. The issue is that it seems to get "corrupted", so that after some time (after someone else has accessed the Xcode project file), when I try to go and open it again I get a Base SDK Missing error. In the Project Settings, I discover that I'm missing the valid ARM6/ARM7 architecture for iOS apps—I can only choose from 32-bit or 64-bit Intel. My only other options are i386, various forms of PPC, and x86_64. I simply can't build for iOS anymore.
No one else that I'm working with seems to have this problem. It exists in both Xcode 3 and 4, so it's not an Xcode 4 issue either.
Is anyone else having this problem? Is there a fix?
Hehe...turns out that the project had been used under the 4.2 SDK and at the time I only had 4.0, which explained the missing SDK part...Updated to 4.2 and it's all fixed now.
Source control would've been nice, but there aren't that many good ones that support the features we need (for free); if anyone's got a guide to installing Subversion on OS X and using it (without being too technical read Terminal), I'd appreciate that. Or how to set up Git with Xcode 4 (although I know that's under NDA, so that's probably not going to happen).
