From Complex to Seamless:Succeeding in codebase migrations
summary
Skyscanner migrates hotels from React Native to native with a goal to remove RN, adopt Compose and SwiftUI, and leave a maintainable foundation; the team uses upfront system design, a skeleton approach to validate integrations, decision logs and Mirror for documentation, and heavy pairing across a seven‑hour timezone split. Kotlin Multiplatform is explicitly rejected as too risky. After focused work and knowledge sharing, the first complex hotels search screen reaches near‑release in about three months, and subsequent screens become faster to deliver.
