Testing reveals that dynamic frameworks work across all build configurations, while two debug static frameworks fail at runtime with a 'runtime injected twice' error. Naming conflicts between frameworks are manageable by qualifying class names with their framework prefix. However, passing custom objects between frameworks does not work — only primitive types and built-in Swift/Obj-C types like String, Bool, and collections of compatible types are interchangeable. The practical recommendation is to keep Kotlin iOS frameworks minimal, as shared dependencies between frameworks are not binary-compatible. ## Full article daily.dev links to this article rather than hosting it.
