Duration

3 days

Overview

This is an intermediate course from iOS Application Development - Introduction. During this course, you will create a reasonably complex iOS program. In the process, it covers storyboards, table view, table view controller, editing table view, navigation controllers, camera, auto layout, gesture recognisers, push view controllers and modal view controllers. You will also learn how to use unit tests and debugging tools.

Course Pre-requisites

Knowledge of a programming language is required.

It is recommended for participants to go for the iOS Application Development - Introduction course prior to attending this course.

Day 1

Getting Started

  • Get the tools

Learn the essentials of Swift

  • Differentiate between a constant and a variable
  • Know when to use implicit and when to use explicit type declarations
  • Understand the advantage of using optionals and optional binding
  • Differentiate between optionals and implicitly unwrapped optionals
  • Understand the purpose of conditional statements and loops
  • Use switch statements for conditional branching beyond a binary condition
  • Use where clauses to impose additional constraints in conditional statements
  • Differentiate between functions, methods, and initializers
  • Differentiate between classes, structures, and enumerations
  • Understand syntax for (and basic concepts behind) inheritance and protocol conformance
  • Determine implicit types and find additional information using Xcode’s quick help shortcut (Option-click)
  • Import and use UIKit

Build a basic UI

  • Create a project in Xcode
  • Identify the function of key files that are created with an Xcode project template
  • Open and switch between files in a project
  • Run an app in Simulator
  • Add, move, and resize UI elements in a storyboard
  • Edit the attributes of UI elements in a storyboard using the

Attributes inspector

  • View and rearrange UI elements using the outline view
  • Preview a storyboard UI using the Preview assistant editor
  • Lay out a UI that automatically adapts to the user’s device size using Auto Layout

Connect the UI to code

  • Explain the relationship between a scene in a storyboard and the underlying view controller
  • Create outlet and action connections between UI elements in a storyboard and source code
  • Process user input from a text field and display the result in the UI
  • Make a class conform to a protocol
  • Understand the delegation pattern
  • Follow the target-action pattern when designing app architecture

Day 2

Work with View Controllers

  • Understand the view controller life cycle and when its callbacks occurs, such as viewDidLoad, viewWillAppear and viewDidAppear
  • Pass data between view controllers
  • Dismiss a view controller
  • Use gesture recognizers as an additional level of generating events
  • Anticipate object behavior based on the UIView/UIControl class hierarchy
  • Use the asset catalog to add image assets to a project Implement a Custom Control
  • Create and associate custom source code files with elements in a storyboard
  • Define a custom class
  • Implement an initializer on a custom class
  • Use UIView as a container
  • Understand how to display views programmatically

Define your data model

  • Create a data model
  • Write failable initializers on a custom class
  • Demonstrate a conceptual understanding of the difference between failable and nonfailable initializers
  • Test a data model by writing and running unit tests

Day 3

Create a table view

  • Understand the key components of a table view
  • Create and design a custom table view cell
  • Understand the roles of table view delegates and data sources
  • Use an array to store and work with data
  • Display dynamic data in a table view

Implement Navigation

  • Embed an existing view controller within a navigation controller in a storyboard
  • Create segues between view controllers
  • Edit the attributes of a segue in a storyboard using the

Attributes inspector

  • Pass data between view controllers using the prepareForSegue(_:sender:) method
  • Perform an unwind segue
  • Use stack views to create robust, flexible layouts

Implement Edit and Delete behaviour

  • Differentiate between push and modal navigation
  • Dismiss view controllers based on their presentation style
  • Understand when to use different type cast operators for downcasting
  • Leverage optional binding to check for complex conditions
  • Use segue identifiers to determine which segue is occurring

Persist Data

  • Create a structure
  • Understand the difference between static properties and instance properties
  • Use the NSCoding protocol to read and write data

Submitting your App to the App Store

  • Create an Apple Developer account
  • Create Developer Certificates
  • Create your app’s App ID
  • Register your device
  • Create profiles
  • Create an icon for your app
  • How to take screenshots of your App
  • Uploading your App to the App Store
