Discontinuing Swift Language IDE Support in the Kotlin Multiplatform Plugin

Article Summary

Anton Makeev from JetBrains just announced they're pulling Swift IDE support from the Kotlin Multiplatform plugin. If you're building cross-platform apps, this shift reveals where the ecosystem is actually heading.

Starting with IntelliJ IDEA 2026.3 and Android Studio Rabbit 2, JetBrains is removing Swift editing, syntax highlighting, and navigation features from their KMP plugin. The decision comes after telemetry showed limited and declining usage, as most iOS developers prefer Xcode while KMP teams increasingly adopt full Kotlin and Compose Multiplatform stacks.

Key Takeaways

Critical Insight

JetBrains is betting on Kotlin-first multiplatform development over hybrid Swift/Kotlin workflows based on actual developer behavior patterns.

The article hints at how this decision connects to broader shifts in cross-platform architecture choices that engineering leaders are making right now.

About This Article

Problem

JetBrains built Swift tooling in AppCode, an IDE that's no longer maintained. The team has to keep updating it as Swift, Xcode, and the IntelliJ Platform change, which takes significant effort.

Solution

The Kotlin team looked at telemetry data and talked to users to see which features people actually used. They decided to stop developing Swift IDE features but keep iOS debugging and Kotlin/Native features like Swift Export working.

Impact

JetBrains is shifting engineers to work on Kotlin tooling in IntelliJ IDEA and Android Studio, and improving KMP for iOS developers. Swift IDE features will stay in older plugin versions but won't get any new updates.
