The fundamental tool for creating applications on Apple’s mobile operating system is a programming paradigm employed to translate human-readable instructions into code that the device can execute. A prominent example of this is Swift, Apple’s modern, performant, and type-safe system-level application programming system.
Its proper selection is critical for application success, affecting performance, development speed, and maintainability. Historically, Objective-C served as the primary option, but Swift’s introduction brought significant improvements in security and developer experience, leading to its widespread adoption and a richer ecosystem of libraries and frameworks.
