Swift is a general-purpose, multi-paradigm, compiled programming language developed by Apple Inc. It is designed to work with Apple's Cocoa and Cocoa Touch frameworks and the large body of existing Objective-C code written for Apple products. Swift makes it easy to write software that is very fast and safe by design.


The main uses of Swift:

Cloud services

Systems programming

General purpose mobile apps, from simple ones to backend driven mobile products with web counterparts

01 An emphasis on safety

by putting restrictions on some developer decisions, which in turn might save time in the long run

02 Fast performing and predictable

just like C-based languages (C, C++, and Objective-C) to which it is often perceived as an alternative

03 Open source

leading to a large supportive community along with many third-party tools

04 Easy to scale

therefore ensuring that the products which use it are future-proof and can be extended with new features when needed

"Swift made me move to iOS development. It's modern, readable, type-safe and extremely fast. Last but not least, it allows us to join the Apple ecosystem with our apps."
