Swift 4
Swift 4 is the latest version of Swift developed by Apple for iOS and OS X development. It inbuilt the features of Swift 3 and improve its robustness and stability. Swift 4 has enhanced the library, includes features like smart key paths and serialization, shortened build times and size of app binaries.
Swift 4 introduced a playground feature in which programmers can write their code with live preview. Swift 4 unifies the procedural and object-oriented portions of the language.
Swift 4 follows a modern programming practice to deal with programming errors:
- In Swift 4, variables are always initialized before use.
- Array indices are checked for out-of-bounds errors.
- Optionals ensure that nil values are handled explicitly.
- Integers are checked for overflow.
