Make Your First iPhone App. 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 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.

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.)
