Swift’s Role in Modern iOS Development

This lesson positions Swift as the working language for modern iOS development: the code you write for app logic, user interface behavior, data flow, networking, persistence, and platform integration.

You will learn why Swift is central to both SwiftUI and UIKit projects, how its safety features shape everyday iOS code, and what parts of the Apple development stack Swift connects to. The goal is not to master syntax yet, but to understand where Swift fits before writing larger app code.
