Kotlin For Swift Developers
summary
Kotlin shows concrete, Swift-friendly parity: val vs let for constants, identical optional syntax that reduces null crashes, and familiar generics plus map/filter. Key gotchas include Kotlin’s parameter shorthand it instead of Swift’s $0 and the reduce/fold mismatch—use fold when you need an initial accumulator. Tooling details: IntelliJ/Android Studio plugins, try.kotlinlang.org sandbox, Kotlin/JS cross-compilation, and Kotlin/Native via LLVM which compiles to machine code but remains experimental and not yet production-ready.
