Swift is a modern combined programming language introduced by Apple in 2014. Originally developed as a replacement for Objective-C, the primary programming language for all Apple platforms, Swift was intended to provide developers with a faster and more efficient development experience.
To this end, Apple's design team created a logo featuring a stylized image of the Swift bird. The bird symbolizes freedom and mobility - two key concepts of the language. The simplicity and efficiency of the logo is also intended to illustrate other core values of the language - speed and mobility.
The term "Swift" itself also reflects the philosophy of the language. Fast, efficient and modern, Swift is a powerful tool for developing robust and scalable applications.
