Even though Clark Cox hasn’t updated his blog in a while now1, he still has one post I don’t want to forget: “SDKs and Deployment Targets”, which walks through the Base SDK vs. Deployment Target Xcode settings. They can be confusing, but they’re vital to understanding how to build your app correctly.
Blogged it! Now I won’t forget.
