Is this used outside the Apple eco-system much? I admit I haven't looked at Swift in 2 years or more.<p>I find the omission of features like namespaces really strange. I realize that namespaces don't jive with how Obj-C and Obj-C frameworks see the world and that Swift and Obj-C need to play together, but dealing with global namespace pollution and collisions in 2018 just seems...sad? They're hobbling the language in various ways due to NS*/Cocoa framework stuff.<p>Another weird omission is lack of any kind of concurrency story. Right now, this just seems like Apple's "me-too" version of Java/C#, but what does it actually bring to the table that would make it a worth-while investment if I'm not an iOS developer?
