Get Ready to Learn iOS

Welcome to the iOS Nanodegree! This is where your journey to become an iOS developer begins. Learn about the structure of the program, and determine the best path for you.

Variables and Types

Learn about one of the most basic building blocks of nearly every programming language. Variables give developers the ability to store information that can be used to control the behavior.

Operators and Expressions

Add, subtract, multiply, divide, and more using operators and expressions in Swift!

Control Flow

Learn how to control when and how Swift code is executed by using if and else statements.

Functions

Learn how to define and use functions, which give developers the ability to bundle up code so that it can be reused multiple times.

Structures and Enums

Learn how to declare and use structures, or structs, in Swift, and explore Enums, a type that can represent any value in a set of related values.

Optionals

Why does Swift need this data type that no other language has? Join us as we get to the bottom of this mystery, and learn optionals inside and out.

Strings

Playing with Strings is a lot of fun. In this lesson, we'll explore Swift’s String struct, and practice some common string manipulations.

Collections

It’s time to explore collection types, including Arrays and Dictionaries.

Object-Oriented Programming

Learn foundational concepts of object oriented programming, including classes, inheritance, and polymorphism.

Introduction and Xcode

An introduction to Swift and Xcode. Swift is Apple's fast-growing programming language for building iOS apps and much more. Xcode is the programming environment used to create native Apple applications with Swift.

Welcome to Part 2!

So far, you've focused largely on UIKit and various UI elements of your apps. Now, you'll learn how to deal with network requests and storing data to the device.

Prereq: Associated Values

Associated values are values that can be attached to enum cases. In this lesson, learn how to use associated values to enhance enums while simultaneously improving their readability and conciseness.

Prereq: Guards

Guards, or guard statements, specify conditions that must be true for execution to continue. By using guards, you can create preconditions and safely control execution.

Prereq: Errors

In this lesson, learn how to handle errors in Swift. These errors, unlike warnings or issues raised by the compiler, are generated in situations where correct behavior cannot be guaranteed.

Prereq: Generics

Generics is one of the most powerful features in Swift. It powers Swift arrays, dictionaries, and collections, and it can be used to apply functionality to specified types.

Prereq: Closures Reloaded

Learn about closures, an alternative syntax to functions, as well as how `typealias` allows you to rename existing types.

Using AutoLayout

In this lesson, you will learn about the 4 different ways of implementing AutoLayout, which one we recommend you use, and why. You also will delve deeper into the recommended way: UIStackViews.
