I share it. I love Objective-C and feel its a far superior language over Swift. Swift is too clever by half, with its var, let, func, and the god awful question marks. Objective-C is verbose sure, but that helps readability. I'll never switch to Swift, as Objective-C is so much better in every single way.
I have on both counts. I tried it a couple times and hated it. I've read the book and others justifications for it, but disagree.
Swift is absolutely less readable than Objective-C. Objective-C is known for its verboseness, which makes it easy to read. Swift has all kinds of easy ways to make it less readable, like the question mark. There is no way one can objectively argue Swift is more readable than Objective-C.
