Explore classes as blueprints in swift, create dog and bottle classes with properties, and instantiate independent objects to manage attributes like name, color, and age.

Explore how methods—functions inside a class—are called on objects, using a dog example to print bark, display info from properties, and double the age with a new method.

Move from an array of strings to an array of joke objects, replacing if statements, and wire the definition view controller to show each joke’s title and text. Introduces optional types.

Explore how Swift optionals represent values that may be nil, learn safe unwrapping with if let, and apply these techniques to convert strings to numbers without crashing.

Build a to do list app to input and check off tasks, while honing table views, new app setup, and navigation controllers toward future core data saving.

Sketch a to-do list app with three view controllers, an add screen for name and importance, plus button, a red exclamation for urgent items, and chordata saving in Xcode.
