What is the oldest version of OS X that CMake actually runs on? I guess I would support the last version of Xcode that actually ran on that platform. In reality this is probably 10.6.8? But At the next major update of CMake (3.5 or 3.6) I would actually draw a line in the sand and pump that up to OS X 10.9, 10.8 at the absolute minimum. I think that is Xcode 6?

Just my thoughts.

I personally am not using them. My more serious problem is that the
Xcode projects being generated now are not keeping up with modern
Xcode and the features that need to be accessible/set. The reality of
Apple development is you must be on the latest stable Xcode if you
need to ship apps on the Mac or iOS Store, otherwise Apple can reject
your app. Their design philosophy, regardless if you agree with it or
not, is to build with the latest and build against backwards
compatibility deployment targets, not build with the oldest and pray
it will work with future changes that couldn't be predicted at the
time. Their platform, their rules.

So I'm all in favor of dropping legacy platforms if it means
ultimately helping make the Xcode generator work better for modern
Xcode. General rule of thumb for Apple development is support the
latest and -1 version. If you can do more, fine, but don't compromise
the recent stuff in order to achieve distant backwards compatibility.

Hello,

I'd like to get your feedback on deprecating or dropping support for
older Xcode versions. During changes on the Xcode generator it gets
harder and harder to test against old and very old Xcode versions like 3
and 4.

Are there still users around for these versions of Xcode?

PS: I'm talking here about the Xcode generator which creates Xcode
projects, not the Makefile or Ninja generator.

Thanks,
Gregor
