Navigating Kotlin Multiplatform beyond the happy path

Moving beyond theoretical tutorials reveals concrete friction points and unexpected crashes in real applications.

#2 about 7 min

Swift and Objective-C interoperability limitations and tools

Sealed hierarchies and typed generics often degrade through the traditional Apple bridge, requiring supplementary ecosystem tooling.

#3 about 4 min

Bridging Kotlin exceptions to Swift error handling

Unannotated Kotlin exceptions silently crash iOS applications, making explicit result types a preferable design choice.

#4 about 7 min

Build performance and Xcode tooling friction for iOS

Native compilation overhead and fragmented debugging environments complicate the daily workflow for native iOS developers.

#5 about 3 min

Testing and accessibility in Compose Multiplatform on iOS

Shared user interfaces can act as opaque views in legacy testing environments, requiring careful validation of accessibility guarantees.

#6 about 5 min

Architectural boundaries and the Kotlin Multiplatform survival kit

Selectively sharing business logic over user interfaces while implementing proactive workarounds minimizes friction across platforms.

#7 about 2 min

Designing cross-platform APIs with team collaboration
