Overview

Xcode and iOS Apps

• Views are in .storyboard files
• code that operates on the views is in a UIViewController
• a UIViewController is linked to each screen in the storyboard

The Code

• Variables (also known as Objects): Store data about something (such as a UILabel in the view, or a piece of text)
• Functions: named blocks of code that can be run

Programming

• Computer/Phone runs the program line by line
• 'Comments' are used to tell the computer to ignore lines of code (useful for keeping notes in the code)
• in Swift comments are created with // for single line comments or /* stuff here */ for multi-line comments

Swift

• The language we have been working with. Created by Apple and primarily used for making iPhone/Mac apps.
• 'Statically typed'

Functions

Each function has

• parameters (what variables the function takes)
• return type (what the fucntion returns, if anything)

// No return type
func printNum(num: Int) {
 print(num)

Control Structures

Control structures are things you can put in your code to perform various logic operations. (i.e. perform a line of code multiple times)

There are a few but there are 2 important ones to know:

• if statments
• for loops

if Statements
