iOS 9 and Swift 2: Step It Up!

Explore inheritance by creating a retirement account that inherits from bank account, reusing base functionalities while adding a financial advisor and age properties and a new adviser method.

Learn how encapsulation protects data integrity by hiding the bank balance with private access and a get-only property, and enforce updates through deposit and withdrawal methods.

Explore abstraction in Swift: focus on what an object does, not how it does it, hiding complexity to see the big picture. Compare abstract classes and encapsulation to guide design.

Explore how object oriented programming powers iOS frameworks and Foundation, using UIKit to build user interfaces quickly in Xcode with prebuilt components and documentation.

Explore how the model-view-controller communicates through target-action, outlets, data source, delegation, and notifications in a blind, structured flow, with practical examples and upcoming coding demonstrations.

Learn how delegation and protocols form contracts for controllers, implementing mandatory methods while optional ones remain, using data source protocol and search results updating in iOS apps.

Explore the iOS application lifecycle from launch to termination, learning how UI application and its delegate manage state transitions via the main run loop, singleton, and notifications.

Explore the view controller lifecycle from storyboard instantiation to view did load and view did appear, with on-screen transitions in a music video app demo, plus source control integration.

Explore Git basics on the command line, including distributed version control, master and feature branches, commits with messages, staging, merging, and using a remote repository for team development.

Learn how to set up a GitHub repository, generate RSA SSH keys, and securely push code to a public remote using git commands such as git push origin master.

Learn how to manage source code with Xcode and GitHub, including creating branches, committing changes, merging into master, and syncing with a remote repository.

Create a free GitHub account, set up a repository, and practice push, pull, and commit while connecting local work to remote repositories for collaboration and version control.

Configure your Apple ID in Xcode and set up a git repository with branches for each session. Connect to a remote repository using SSH keys and follow model-view-controller patterns.

Develop a color API manager to fetch the iTunes API with NSURLSession, handle completion, dispatch to the main queue, and display results via a UI alert controller.

Create a music video data model by parsing json into class properties with a custom initializer that takes a dictionary, enabling data encapsulation and ready-to-display UI data.

Reinforce backend and API skills by building a new app that consumes an API, creates a fresh class, and types code from scratch for front-end integration.

Compare table view and table view controller in iOS 9 and Swift 2, explain when to use each, and outline data source and delegate roles with reusable cells.

Build a custom cell in an iOS app by importing a resource image, displaying rank and music title in two labels, and pulling the top 200 from the iTunes API.

fetch images from a url in a background thread, cache them in an array, and update the user interface on the main thread to enhance performance with cell reuse.

Enable app transport security and allow arbitrary loads to fetch images from the iTunes API, demonstrate background image loading, and compare array data versus network calls for performance.

Learn to implement preferred fonts for a flexible UI, updating fonts dynamically in table view cells and other screens via observers when content size changes.

Select one of five APIs, register for a token if needed, and build an app that consumes the API, structures its data, and presents it in a UI table.

Create a music video detail screen in storyboard, linking a detail view controller to the navigation flow, and lay out image, labels, and toolbar per design specs.

Tap a table row to pass data to the detail screen, populating the image, name, price, and studio for the selected music item via a music detail segue.

Store and retrieve small user preferences with NSUserDefaults, including a security Touch ID switch and a slider setting, so choices persist across app launches.

Use a slider with NSUserDefaults to persist settings, setting min and max values, saving the slider as an integer, and restoring it on app launch for a smooth user experience.

Tune the app to adjust image quality based on reachability; wifi uses 600x600, cellular or off to 300x300, and disable Touch ID security when unavailable, with an explanatory label.
