Learn how to create and manipulate arrays in Swift, including indexing with zero-based counting, checking length with count, and using append, insert, update, and remove operations.

Learn how to implement table views in iOS by using a table view controller, wiring storyboard and code, and linking the code term table view controller via the identity inspector.

Learn to populate a table view by answering two questions: how many rows and what goes in each cell, using a table view controller and cell text label.

Master segues in iOS 13 apps by embedding a table view controller in a navigation controller, adding a code dictionary title, and triggering a defined segue via did select.

Create a code view controller, connect it to storyboard, and pass a selected string between screens using prepare for segue, updating the destination code view controller's term and navigation title.

Connect the definition label as an outlet in the view controller and set its text with an if statement to show each coding term’s definition.

Learn loops in Swift, using for loops to run code over ranges and across arrays, printing items like fave candy.

Learn how to define classes in Swift, create objects with properties, and access them via dot notation, using a water bottle example to illustrate class conventions and object oriented programming.

Define methods as functions inside a class using a dog example, returning info with string interpolation and updating age via a double method, with self usage.

Create a term class with properties name, definition and is type, then build an array of term objects and display names or definitions.

Learn how optionals work in Swift, how a value can be nil, converting strings to integers yields optional ints, and safe unwrapping using if let to avoid crashes.

Fix navigation crashes by safely passing a term object between view controllers with optional checks. Use classes and term properties like name and definition to customize the user interface.

Create a table view controller embedded in a navigation controller titled to do list, define a to do class with name and important, and display items with exclamation for important.

Learn to use a plus bar button item to segue between views, then design a form with labels, a text field, a switch, and an add button.

Prepare for segue to pass a reference to the create-to-do screen, then append the item to the array and refresh the table view after popping back with the navigation controller.

Create a core data entity named to do item with name and important attributes to enable long-term storage and retrieval of to-do items across app launches.

Create and save a to do item in core data by accessing Chordata's to do item entity through the app delegate's persistent container, then save the context.

Fetch to do items from Core Data using a fetch request and context when the view appears, unwrap optional properties, and refresh the table view to display updated data.

Learn how to delete a to do item from Core Data, using a proper context, saving after deletion, and simplifying code with Chordata.

Build a single-screen iOS app with a table view in a navigation controller, add a core data 'hello' item via a plus button, and delete items on tap.

Create a hello app by wiring a Core Data stack, a table view controller, and a navigation bar; implement add, delete, and data reload using a fetch request.

Create the progress journal app that captures photos with the device camera or gallery, stores progress entries with Core Data, and displays images in a table view.

Design a two-screen flow with a navigation controller and table view, a plus button opening a detail view, and display an asset image in an image view with aspect fit.

Learn to create rounded buttons in iOS apps with Xcode 11 and Swift 5, including equal widths, centered layout, color background, and corner radius.

Learn to use the built-in image picker controller to select photos from the photo library or camera, present the picker, and handle the chosen image via the delegate.

Explore dictionaries as a swift collection that stores key-value pairs, letting you access values by keys like Fido: 6 and Sean: 18, with no guaranteed order.

Save the image and title to core data by creating a progress update entity with image as binary data and a title string, then persist and return.

Learn to fetch progress updates from Chordata, display them in a table view, show titles (and images later), and implement swipe-to-delete to remove items via Core Data.

Connect apps to the internet to download data by building a bitcoin price tracker that shows USD, euros, and yen, with a reload button and last-price caching via user defaults.

Design the Bitcoin price tracker user interface with a navigation bar and edge-to-edge constraints, featuring a Bitcoin image and a scalable price label using minimum font size.

Fetch bitcoin prices using an api and a url session data task, retrieving standardized json for usd, jpy, and eur, with error handling and success verification in the app.

Fetch data from a URL, convert the response to text with UTF eight, and parse JSON into a [String: Double] dictionary to read the USD, EUR, and JPY prices.

Explore threading in iOS apps by moving network work off the main thread and updating the UI on the main thread with a dispatch queue, outlets, and a refresh action.

Demonstrate saving api results to user defaults and retrieving them on startup to show stored prices for usd, eur, and jpy after a loading state.
