Swift.
First, they added features that no developer understand : what the fuck is an optional value ?
And the documentation for iOS development is horrible. It took me 5 days to understand how the fuck we can make a POST HTTP Request with this fucking bad framework.

I love Swift, so does my team. I happen to love optionals personally, and would not in a million years say nobody understands them.

It is an amazing idea to force developers into remembering to check for null before doing something stupid.

I quite like the layout of having a guard check at the top of the function, making all the important checks and declaring safe variables for the rest of the code.

Swift is not same as iOS. If the iOS docs are not good this does not mean that Swift is a bad language. In fact most of iOS SDK is written in Obj-C.

@divil Exactly ! Thanks !
