Algebraic Data Types in Swift
summary
Claims that using Swift enums as ADTs and pushing invariants into the data model eliminates many invalid UI states, reduces switch-with-default bugs, and lets the compiler catch errors early. Demonstrates a dessert app with donuts, toppings and a secret-ingredient type, adds hashable semantics to make sets work, and uses a small codegen to provide a match method so exhaustive cases compile. Integrates layout via Theodolite component layout, components remain pure, the demo compiles and behaves as expected.
