Type Inference and Explicit Types

Swift is a *statically typed* language — every value has a type known at compile time. But you rarely need to write the type yourself because Swift infers it for you.

Swift examines the value on the right-hand side and deduces the type automatically: ```swift let message = "Hello" // inferred as String let count = 42 // inferred as Int let price = 9.99 // inferred as Double ``` No type annotation needed — the compiler figures it out.
