Swift is a general-purpose, multi-paradigm, compiled programming language developed by Apple Inc. for iOS, macOS, watchOS, tvOS, and Linux. Swift is designed to work with Apple's Cocoa and Cocoa Touch frameworks and the large body of existing Objective-C (ObjC) code written for Apple products. Read more on Wikipedia...


Example from Compiler Explorer:
// Type your code here, or load an example. func square(n: Int) -> Int { return n * n }
Example from Riju:
print("Hello, world!")
Example from hello-world:
print("Hello World")
Example from the Hello World Collection:
// Hello world in Swift println("Hello, world!")
Example from Linguist:
println("Hello, world")
Example from Wikipedia:
var someSortOfPrintableObject: SupportsToString ... print(someSortOfPrintableObject.toString())
