I go back and forth. I do miss the simplicity of objc at times though. I think in a short amount of time someone can become close to an expert in objc. Swift is already incredibly complicated and there's no end in sight.
I hate how pendantic and useless some of the features of swift being pushed down by academics that don't write apps or services themselves.
Simple example:
Objective-C
if myObject {
}
in swift if myObject != nil {
}
Also opitionals in swift could have totally be avoided if they adopted a prototype based langue (basically object are never nil). Lua did this, and it is very elegant
But meanwhile, we got a half backed optional system, which is backwards (similiar to Java), and didn't help with the practicality of the language at all, and meanwhile you still can crash an app doing myArray[1]
A few years from now O'reilly will publish a bestseller called Swift: The Good Parts
