SpaceAdventure
Level 1, Fifteen Lessons
Teach the fundamentals of object-oriented programming with Swift. Guide students in discovering Swift syntax, conventions, modeling with classes, initialization, optionals, data structures, and closures.
The Finished App
Familiarize yourself with the project, and demonstrate the app students will build.
Lesson 1
Introduce basic variable and constant declarations, string interpolation, and printing to the console with print.
Lesson 2
Practice calling functions and using return values. Introduce control flow and Boolean logic.
Lesson 3
Demonstrate using a loop and logical operators to validate user input.
Lesson 4
Create a Swift class. Demonstrate instantiating an object and calling a method.
Lesson 5
Demonstrate how to implement a simple method.
Lesson 6
Practice implementing and calling methods, declaring parameters, and explain Swift access control.
Lesson 7
Practice implementing a class, and demonstrate the relationship between properties and initializers.
Lesson 8
Motivate the need for an array, and introduce array type annotations and creation.
Lesson 9
Practice declaring properties and defining initializers, and associate variables with mutability.
Lesson 10
Practice argument passing, object instantiation and appending to arrays.
Lesson 11
Compare traditional for loops with a for-in loop, and iterate over a data structure.
Lesson 12
Demonstrate pseudo-random number generation and Swift type conversion.
Lesson 13
Motivate the need for optionals, and demonstrate computed properties and optional binding.
Lesson 14
Refactor to illustrate the relationship between variable and constant properties, and initializers.
Lesson 15
Introduce dictionaries, and use a for-in loop to motivate the use of map and a trailing closure.
