Svift (engl. Swift) je programski jezik opšte namene. Podržava imperativni, objektno-orjentisani i funkcionalni način programiranja. Stvoren od strane preduzeća Epl da bi zamenio Objective-C pri programiranju iOS i OS X programa.[3] Napravljen je upotrebom LLVM programskog prevodioca koji je dostupan u Xcode 6 beta.

Uputstvo na 500 strana, The Swift Programming Language, predstavljeno je na WWDC-u i dostupno na iBooks Store besplatno.[4]

Zvanična aplikacija WWDC je 2. juna 2014. postala prva javno dostupna aplikacija napisana u Sviftu.

I implemented much of the basic language structure, with only a few people knowing of its existence. A few other (amazing) people started contributing in earnest late in 2011, and it became a major focus for the Apple Developer Tools group in July 2013 [...] drawing ideas from Objective-C, Rust, Haskell, Ruby, Python, C#, CLU, and far too many others to list.«
