Swift is an industrial-quality programming language that is as enjoyable as a script language, according to Apple.
Swift is a programming language with more features. This is relevant to the earlier versions of the Swift programming language because Swift has already replaced Objective C.
Swift was introduced to the world in 2014), but the language is only 7 years old compared to Objective C, which has been around since the 1980s. The recent modify brought stability to the Apple platform, as well as Swift compatibility. Swift needs to be made a more mature language.
Swift is still small compared to other open source languages
Swift is strong, static typing and the existence of optional types means it fits into a class of languages like Rust or Haskell. Java is a type system that is not as good as those languages. It has a lot of parallels with swift, but I never used it.
Both of them are built on top of an older OO language with inferior type systems that they have to interop with.
They both add a more powerful type system with type inference, they do not require a lot of FP style, and they eliminate a lot of cruft and boilerplate of their parent language. I'm pretty sure I heard someone refer to Swift as Obj-C, Obj-C, which seems to be an accurate description.
Why does Apple use Swift?
Swift is a robust and intuitive programming language created by Apple for building apps. Developers will be given more freedom than ever. Swift is open source and easy to use, so anyone with an idea can create something amazing.
Swift is becoming more popular on Apple's platforms despite the fact that Apple has not announced plans to sunset the Objective-C language. Many Swift Evolution suggestions were taken into account by Apple.
Swift was introduced at Apple is On Apple systems.
