I bounced off of Objective-C not because of its message-passing OO. That was the actual cool part. I bounced off because of the insane amount of boilerplate prototyping and headers required to use it.

I think every OO language should be using Smalltalk's message-passing style rather than holding hard references, and Objective-C is a great model. But discard the rest.

Apple should have made a modern Smalltalk on top of the Objective-C object model as a replacement for Objective-C instead of Swift.

I want to love Swift, but the funny thing is that as they solve more problem with Swift they also add so much complexity that you wonder if all the problems they solved just added new problems.
