Pass data between view controllers with prepare for segue to hand off a player model from the league view controller to the skill view controller.

Design responsive interfaces with auto layout across iPhone and iPad using size classes and traits to tailor layouts, hide or show elements, and adapt fonts.

Learn to use auto layout and size classes to adapt an iPad interface without breaking the iPhone design, using installed variations, constraints, and stack views for responsive alignment and spacing.

Develop a window shopper app in iOS using Swift, build a reusable currency text field with custom styling and attributed placeholders, and implement Interface Builder to match runtime appearance.

Learn to use IBDesignable and prepare for Interface Builder to see live changes, then create an input accessory view with a programmatically added calculate button for text fields.

Create the wage model and its unit tests to compute hours from price and wage, applying ceiling to round up, and emphasize modular, testable business logic.

implement the remaining ui and app logic to compute hours from wage and price, with outlets, actions, validation, and a currency icon proposal to avoid formatting issues.

Build a coder swag app from scratch by creating an Xcode project, setting up Git, and implementing custom table views with IBOutlets to display data-driven lists.

Create a category data model, supply data through a singleton service, and populate a table view using its data source and delegate with titles and images.

Learn to use a collection view instead of a table view to display a two-column grid of products, with a custom collection view cell containing image, title, and price.

Define a Swift struct Product with title, price, and imageName, then implement a hard-coded data set and a switch-based getter to fetch hats, hoodies, shirts, and digital goods by category.

Learn to wire table view selections to segues, pass category data to a products VC, and populate a collection view with products via a data service.

Describe how model view controller separates data, UI, and logic using a blueprint, a view, and a coordinating controller. Apply MVC by building a small iOS app in practice.

Create a new Xcode project as a single view application and explore the project navigator, app delegate, view controller, storyboard, assets, launch screen, and Info.plist to begin mvc.

Set up an iOS project with groups for model, view, and controller in Xcode, organize with Interface Builder and storyboard, and understand how the view controller displays model data.

Create a model layer by defining an Apple product class with properties name, color, and price, and implement an initializer to build instances for display in the app.

Subclass UIView to make a custom view, override awakeFromNib, and set corner radius, shadow, background color, and border via the layer. Assign the class in storyboard and explore IBDesignable/IBInspectable.

Connect view controllers to labels and a hardcoded model to display Apple product data using outlets, a stack view, and constraints, illustrating the model-view-controller pattern in action.

secure the model layer by converting properties to private and exposing a public getter with a private setter in Swift, ensuring data initialized only within the class.

Model Apple product with name, color, and price in an mvc-driven app; create a Samsung product model and a custom UI label subclass, modifying awakeFromNib and coding a second label.

Explore the accelerometer in iOS apps, learn how to read x, y, z data, and build a simple interface to capture motion and add parallax effects.
