Kotlin Multiplatform vs Native iOS: 2026 Comparison

Kotlin Multiplatform (KMP) shares business logic between iOS and Android while keeping native UI. Pure native iOS uses Swift end-to-end.

Kotlin Multiplatform vs Native iOS (Swift) — Feature Comparison

Feature	Kotlin Multiplatform	Native iOS (Swift)
UI	Native SwiftUI/UIKit	Native SwiftUI/UIKit
Shared code with Android	60–80% of business logic	0%
Build complexity	High (Gradle + Xcode)	Standard Xcode
iOS hiring	Niche (Swift + Kotlin)	Standard Swift devs

Verdict

KMP makes sense when iOS and Android are equal-priority surfaces and 60%+ of code is non-UI. For iOS-first or iOS-only products, pure Swift wins on simplicity and time-to-market.

Choose Kotlin Multiplatform if

• iOS + Android with shared business logic
• Teams with strong Kotlin expertise

Choose Native iOS (Swift) if

• iOS-first products
• Apps using HealthKit, ARKit, App Intents
• Smaller teams
