About this course

This course teaches programming in the Swift language to develop iOS apps for iPhone. Swift is an open-source language that came as an easier replacement for Objective-C. You start with highlights from the course, then an introduction to the world of the Swift language, followed by programming rules, loop statements, statements that control the flow of the program, and functions. Then you learn object-oriented programming, inheritance, using the Protocol to build the program structure, working with arrays, handling program errors and databases. After that you move on to setting up the work environment and getting to know Xcode, the project interface tools, working with pages and tables, markup languages, and advanced skills. This course suits anyone who wants to learn to develop iPhone apps, whether you are a beginner or know another programming language. You need no previous experience with Swift. The course is divided into many lectures, so you learn each topic on its own and practice it yourself. By the end you will be able to write programs in Swift, design pages and tables, and work with Xcode to build an iOS app.

Expected outcomes

  • Master Swift for professional iOS app development.
  • Design and implement applications using object-oriented programming.
  • Write clean and efficient code.
  • Execute iOS app projects using advanced Swift techniques.
  • Analyze and debug programs effectively.
