Learning Objective-C?

I am starting to learn Objective-C and was wondering if their are any video tutorials / books I should purchase from raywanderlich.com?

Or what order should I watch the video tutorials??

Some of the books include the Objective-C code if they were around before Swift.

The Objective-C tutorials on the site are still relevant. Nothing has really changed with it as long as it happened after around iOS6 (ARC).

Sooo on videos what orders should I take them in?

Starting with the Types and Crash Course

Then I’d recommend doing the Debugging series followed by the Foundation.

The debugging toolchain in Objective-C is currently much better than it is for Swift. It is essential knowledge in my opinion.
