I get compile failures because “NSSegmentedControl” (which I use) is reported to be unavailable on OS X prior to 10.3. Fine.. but I’ve set my project to 10.7 everywhere. Same issues with Clang and GCC.
Is there a limitation to creating 32-bit OSX applications on Lion?


I believe it’s a bug in Xcode.
While the default Deployment document versioning setting for nib files seems to be
Project SDK Version (Mac OS X 10.7)like shown in the image below, Xcode actually seems to be usingAll Versions of Mac OS X.If you change the Deployment target to be a specific version of Mac OS X, rather than the Project SDK Version, (like in the image below), it should prevent the errors.
