Unless you need to support iOS 3.x, you'll get ARC for free for your iOS 5.x _and_ iOS 4.x projects in September with Xcode 4.2 (currently in beta). ARC and non-ARC libraries can also co-exists in the same project.

So it seems quite logical for developers to rely on most modern technologies, esp. since supporting older technologies comes with a cost.

Understood, but technically we're not supposed to submit to the App Store using beta versions of Xcode. Whether Apple would notice is a different story but a rejection would set us back so I'm not willing to risk it.

This isn't a technicality. Apple will reject your app if you compile with Xcode 4.2.

Not for long though, 4.2 is just around the corner. I can't see them doing too many extra betas before releasing it. By the time you develop your app with this library 4.2 is probably going to be released anyway.

We're assuming 4.2 is going to be released soon. No one actually knows. It might be tomorrow, it might be October.

You're right.. but from previous experience, apple doesn't usually do a lot more than 5 or so beta builds.

Still, its not like I'm doing more work anyway, going with ARC saved time on development. If Apple ends up never releasing 4.2, I would just had to "finish" the job.

What about if you just don't want to use Xcode 4.x, because it's (still) missing Xcode 3.2 feature(s) that you use on a daily basis? :)

Looks like a cool library though! Once they manage to make Xcode 4.x work as well as Xcode 3.2, I will try it.

Personally, I thing XCode sucks, either 3x or 4x. It's a really bad environment, I can't see how people use it or like it.

Have you tried AppCode, from JetBrains? Its still in beta, but its magnificent.
