The thing is, understanding Obj-C was never the hard part. For example, understanding ARC, weak vs. strong (and now unowned [1]), and the various libraries is what took time and experience. Swift doesn't solve that at all and in fact offers its own oddities like the below:

“You indicate type methods for classes by writing the keyword class before the method’s func keyword, and type methods for structures and enumerations by writing the keyword static before the method’s func keyword.”

I do think the new language is neat and will be fun to work in, but it doesn't solve the parts that tripped up many people when working in Objc.

        [unowned self] in
        if let text = self.text {
            return "<\(self.name)>\(text)</\(self.name)>"
        } else {
            return "<\(self.name) />"
        }
    }
