If for no other reason, the sheer amount of Objective-C example code out there is reason enough why having Objective-C literacy is a emphatically a Good Thing.

If for no other reason, the sheer amount of Objective-C example code out there is reason enough why having Objective-C literacy is a emphatically a Good Thing. I've found a fun exercise while learning Swift is to re-write Objective-C examples line by line and see how much terser you can make them. The end result is usually worth it, and when it breaks it's always insightful.
