Swift: programming language

Swift is a general-purpose, multi-paradigm, compiled programming language developed by Apple Inc. and the open-source community.

Swift is a powerful and intuitive programming language for iOS, iPadOS, macOS, tvOS, and watchOS.

Apple created Swift, an open-source programming language, as a replacement for all languages based on C, including Objective C, C++, and C. The language was created in 2014 and released to the public as an open-source project in 2015 on Swift.org.

Swift defines away large classes of common programming errors by adopting modern programming patterns:

// Basic Swift Program
import UIKit

var str1 = “Hello geeks!”
var str2 = “How are you?”
print (str1)
print (str2)

Output:

Hello geeks!
How are you?

Note: Import statement is used to import any objective-C framework or library directly into Swift program. var keyword is used for variable and let keyword is used for constant. There is no need of ; for termination, in case programmer uses it compiler won’t show error.
