About the Swift for iOS Concepts Course

Swift for iOS Concepts is a focused Mobile Development course that helps you build a practical foundation in Swift for confident iOS app development. Through clear lessons on syntax, data modelling, safety, reusable patterns, and iOS readiness, you will learn how Swift works in real app scenarios.

Build Strong Swift Skills For iOS Development

  • Learn core Swift syntax, type safety, control flow, functions, and collections for everyday Mobile Development tasks.
  • Build a practical foundation in Swift for confident iOS app development with lessons designed around real iOS concepts.
  • Understand optionals, errors, memory management, and async/await so your app logic is safer and more reliable.
  • Practice Swift for iOS Concepts such as structs, classes, enums, protocols, closures, and reusable type-safe components.

A practical introduction to Swift language concepts for modern iOS app development.

This course guides you through the essential Swift for iOS Concepts needed to read, write, and reason about app code with confidence. You will begin with Swift’s role in modern iOS development, then move into program structure, variables, constants, type safety, operators, conditions, switches, loops, functions, and scope.

As the course progresses, you will learn how Swift handles data and behaviour in real applications. Lessons cover optionals, arrays, dictionaries, sets, structs, classes, enums, properties, initializers, computed values, closures, protocols, extensions, access control, generics, and organised code patterns that support scalable Mobile Development.

You will also prepare for practical iOS work by studying error handling, result-based logic, ARC, memory management, retain cycles, and asynchronous Swift with async and await. By the end, you will be able to connect Swift fundamentals into a working iOS feature and approach Mobile Development with clearer judgment, stronger code structure, and greater confidence.

Foundations

5 lessons

Lesson 1: Swift’s Role in Modern iOS Development

18 min Preview
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.…

Lesson 2: Reading Swift Syntax and Program Structure

19 min
This lesson teaches students how to read Swift source code before trying to write full iOS features. It focuses on the visible structure of a Swift file: declarations, scopes, statements, expressions,…

Lesson 3: Variables, Constants, and Type Safety

20 min
In this lesson, students learn how Swift stores values with variables and constants, how type inference works, and why type safety is central to reliable iOS development. The focus is practical: choos…

Lesson 4: Strings, Numbers, Booleans, and Basic Operators

18 min
In this lesson, students learn how Swift represents everyday values with String , numeric types, and Bool , then use basic operators to combine, compare, and update those values. The focus is practica…

Lesson 5: Control Flow with Conditions, Switches, and Loops

21 min
This lesson teaches the control flow tools Swift developers use every day: if statements, Boolean conditions, switch statements, ranges, pattern matching basics, and loops. Learners practice choosing …

Core Language Skills

3 lessons

Lesson 6: Functions, Parameters, Return Values, and Scope

22 min
In this lesson, students learn how Swift functions package reusable behavior, accept input through parameters, produce output with return values, and keep variables organized through scope. The lesson…

Lesson 7: Optionals and Safe Value Handling

23 min
This lesson introduces Swift optionals as the language feature for representing values that may be missing. Students learn how optional types differ from ordinary values, why Swift requires explicit h…

Lesson 8: Arrays, Dictionaries, Sets, and App Data Collections

21 min
In this lesson, students learn how Swift collections model the everyday data an iOS app needs: ordered lists, keyed lookup tables, and unique groups of values. The focus is on choosing the right colle…

Modelling iOS Data

4 lessons

Lesson 9: Structs and Value-Oriented Modelling

22 min
This lesson introduces Swift structs as the default tool for modelling app data in iOS. Students learn how value semantics make data easier to reason about, how to design small domain models with stor…

Lesson 10: Classes, References, and Object Identity

21 min
This lesson explains how Swift classes model shared, long-lived objects in iOS apps. Learners compare classes with value types, practice reading reference behavior, and learn why object identity matte…

Lesson 11: Enums, Associated Values, and State Representation

23 min
This lesson shows how Swift enums help represent iOS data and app state clearly. You will learn when to use enums instead of strings, booleans, or loose integer codes, and how associated values let ea…

Lesson 12: Properties, Initializers, and Computed Values

20 min
In this lesson, students learn how Swift types hold and prepare data for iOS apps using stored properties, computed properties, and initializers. The lesson focuses on practical model design: choosing…

Reusable Swift Patterns

3 lessons

Lesson 13: Closures and Passing Behaviour Around

24 min
This lesson teaches closures as Swift’s way to package behavior and pass it around. Students learn closure syntax, type signatures, trailing closures, shorthand arguments, capturing values, and the di…

Lesson 14: Protocols and Protocol-Oriented Design

24 min
In this lesson, Professor Peter Lambert introduces Swift protocols as a practical tool for defining shared capabilities without forcing a class hierarchy. You will learn how protocols describe require…

Lesson 15: Extensions, Access Control, and Organised Code

20 min
This lesson shows how Swift extensions, access control, and file organisation work together to make iOS code easier to reuse, test, and maintain. You will learn how to add focused capabilities to exis…

Reliability and App Behaviour

2 lessons

Lesson 16: Error Handling with Throwing Functions and Results

22 min
This lesson explains how Swift models recoverable failure using throwing functions, do-catch , try , and typed error values. Students learn how to define meaningful errors, propagate failures cleanly,…

Lesson 17: Generics and Reusable Type-Safe Components

23 min
This lesson explains how Swift generics help you write reusable code without giving up type safety. Students learn how generic functions, generic types, type parameters, constraints, and protocol-base…

iOS Readiness

3 lessons

Lesson 18: Memory Management, ARC, and Avoiding Retain Cycles

24 min
In this lesson, students learn how Swift manages memory in iOS apps through Automatic Reference Counting, commonly called ARC. The focus is practical: understanding strong references, object lifetimes…

Lesson 19: Asynchronous Swift with async and await

25 min
In this lesson, students learn how Swift's async and await model helps iOS apps perform slow work without freezing the interface. The focus is practical: calling asynchronous functions, understanding …

Lesson 20: Bringing Swift Concepts Together in an iOS Feature
