- Thread-topic: Tech update avoiding legacy code
I may be missing something here, but I have to disagree with some of the version numbers that are being quoted in this thread.
I have an app that supports iOS 5.1.x, which was a requirement since that is that last iOS version supported on the original iPad. It was developed using whatever the current SDK was, but with a deployment target of 5.1. And it uses ARC, GCD, and blocks. Not auto-layout.
My memory isn’t that good about the differences between 5.0 and 5.1, but it is definitely true that 5.1 has a lot more capability in it than has been claimed in this thread.
Cheers,
