No Swift is great language and I did not like Objective-C. The headache in the sense compilation time and also shitty errors come and you do not know what that means.
It's type safe language but all the type safety comes with price and some time the code written is just sucks. Json parsing is one example of this. All the casting and all that really make code horrible.
In swift 3 they made all value types to Any and in iOS communicating between Cocoa frameworks become a really mess as all expect some objc type etc. Implicit conversion is also removed and now you have to cast String to NSString and I really mad about this my code now looks horrible huh....
