Kotlin Multiplatform (KMP) and, more recently, Compose Multiplatform (CMP) have matured significantly in recent years and are gaining increasingly widespread adoption. However iOS integration continues to present its own set of challenges which also vary depending on the amount of UI code that's being shared. In this talk I'll use real world examples to outline a variety of different UI and non-UI patterns I've applied over the last 5 years when using KMP and CMP on iOS.
