About this course

In this course we will build an iPhone app that records a conversation between you and a friend, and then makes your voices sound like a Chipmunk or Darth Vader.

This course will introduce you to iOS app development in Swift, a new programming language from Apple, and serves as your launching point into the iOS Developer Nanodegree.

What you will learn

  1. Introduction to Swift and Xcode: the tools of iOS
    • Learn all the Swift you need to know in 5 min.
    • Take a tour of Xcode, Apple's integrated development environment.
    • Get to know the Model View Controller, or MVC, design pattern
  2. iOS App Structure: AutoLayout and Buttons
    • Learn Storyboard and AutoLayout, the tools used to build user interfaces in iOS.
    • Start developing the Pitch Perfect App and creating the UI.
    • Use Autolayout constraints to control the placement of UIButtons and UILabels on the screen.
  3. Using ViewControllers to build an app with Multiple Views
    • The UIViewController class, View Controller Lifecycle, and Multiple Views.
    • Learn how to react to touch events and change the user interface.
    • Add a second screen to your app using a UINavigationController.
  4. How to record audio and use the Delegation Design Pattern.
    • Learn about the AVFoundation class, AVAudioRecorder.
    • Setup audio recording in the Pitch Perfect App.
    • Practice using the Delegation pattern and implement programmatic segues.
  5. Playback Sound and Add Sound Effects
    • Setup audio playback including rate, pitch, echo, and reverb.
    • Use UIStackViews to create an elegant layout for your app's UIButtons.
    • Use class extensions to add functionality to your app.

Prerequisites and requirements

This course assumes prior programming experience. Specifically, you should have a strong understanding of programming concepts like variables, if statements, loops, functions, and classes. Lesson 1 of Intro to Computer Science and Programming Foundations with Python are good courses to take if you are completely new to programming.

You will also need access to a Mac computer running OS X 10.10 or later.

We have designed this course such that you will not need a physical device (i.e. an iPhone or an iPad) to build your app. We will be using a simulator on your mac that will imitate the features of a phone on your computer. Towards the end of the course we will provide instructions on how to download your app on an iPhone (in case you do have access to a physical device.)

See the Technology Requirements for using Udacity.

Why take this course?

This course will set you on your way to becoming an iOS Developer, where you’ll establish a basic understanding of the iOS ecosystem. You’ll also have working knowledge of Swift, Apple’s custom programming language created exclusively for the mobile developer.

Learn with the best.
