"Run destination My Mac is not valid" error on Xcode 7 beta 5?

I updated from Xcode 7 beta 4 to Xcode 7 beta 5, and I am now seeing an error when I try to build my project:


The run destination My Mac is not valid for running the scheme 'MYSCHEMENAME'.


I've done a Clean, deleted all xcuserdata directories, deleted my DerivedData directory, and nothing's made a difference.


The project has several dependencies on other projects (frameworks, helper apps). All projects are configured to use the 10.10 SDK. Some of the helper app projects are 32-bit only, but the rest are configured to build 64-bit only. I only support 64-bit Macs.


Even after removing the 32-bit projects and build products from the dependencies of my main app, it still gives me that error and refuses to build.


What's changed since beta 4? What can I do to get more information about the error? I suspect it's due to the mixed 64-bit and 32-bit nature of my projects, but when I create new Xcode test projects with that configuration, it works fine.


FYI, xcodebuild yields the same error, so I can't even build on the command line.


Thanks!

Aha!


Xcode 7 beta 5 doesn't include the 10.10 SDK. That's why my projects won't build. (The problem has nothing to do with the 32-bit/64-bit thing.)


Is it supposed to? The previous betas (including beta 4) included the 10.10 SDK.
