Introduction and Xcode

Build your first app with Swift and Xcode, Apple’s programming environment for app development. You’ll learn how to use AutoLayout, UIButtons, and UILabels to create an interface, and how to react to touch events in an app using ViewController and multiple views. You’ll also learn how to set up audio recording and playback in a voice recording app.

Making a Network Request

Incorporate networking into your apps, and harness the power of APIs to display images and retrieve data. Use Apple’s Grand Central Dispatch, or GCD, framework to create asynchronous apps, ensuring a smooth user experience, even while your apps run lengthy operations in the background.

Simple Persistence

Learn about simple persistence, the iOS File System, and the “sandbox.” Set up the classes we need to get Core Data up and running so that we can create, save, and delete model objects. Enable user interfaces to reactively update whenever the model changes, and safely migrate user data between versions.

01. Introduction to Functions

To follow along, open up the Functions playground file from the Learn Swift Programming playground collection.

A function is a list of instructions (code) that accomplishes a specific task. You’ve already seen some examples of functions in Swift.

  • print(“Some text”) is an example of calling the print() function which takes a String and prints it out.
  • arc4_random() is an example of a function that generates a random number (useful for rolling dice!).

Why would we need to use functions for our code? Consider the club screening example from the previous lesson. When screening different clubgoers, we simply uncommented each group of variables. If we wanted to screen all the clubgoers at once, we might do something like the following.

var name = "Ayush"
var age = 19
var onGuestList = true
var knowsTheOwner = true
if onGuestList && age >= 21 {
    print("(name), come party with us!")
} else if knowsTheOwner {
    print("(name), we'll have to take you to the owner.")
} else {
    print("Sorry, (name), maybe you can go play Bingo with the Android team.")
}
name = "Gabrielle"
age = 29
onGuestList = true
knowsTheOwner = true
if onGuestList && age >= 21 {
    print("(name), come party with us!")
} else if knowsTheOwner {
    print("(name), we'll have to take you to the owner.")
} else {
    print("Sorry, (name), maybe you can go play Bingo with the Android team.")
}
name = "Chris"
age = 32
onGuestList = false
knowsTheOwner = false
if onGuestList && age >= 21 {
    print("(name), come party with us!")
} else if knowsTheOwner {
    print("(name), we'll have to take you to the owner.")
} else {
    print("Sorry, (name), maybe you can go play Bingo with the Android team.")
}
 

Yikes! Not only is the code a mile long, but if the club ever needs to change its rules, you’d need to remember to update all the conditions. By the end of this lesson, you’ll be able to use functions to make your code much more readable and less prone to error.
