HOW WE BUILT AN INTERPRETER FOR SWIFT (A COMPILED LANGUAGE)

Summary from the TLDR Web Dev newsletter

Bitrig built a Swift interpreter to dynamically run Swift apps on iPhones without requiring compilation and signing through Xcode. The interpreter uses SwiftSyntax to parse Swift code and represents runtime values using an `InterpreterValue` enum, handling both native and custom types. For framework APIs like SwiftUI, it pre-compiles calls to initializers and other functions, parsing `.swiftinterface` files to automate the process.
