Getting Started

Getting Started

Requirements

• Swift 5.9 or later
• iOS 15, macOS 11, tvOS 14, or watchOS 7
• An exported asynchronous state source

Add the package in Xcode:

https://github.com/sonmbol/KMPObservableBridge.git

Link the product matching the application:

Integration	Product
SKIE StateFlow	KMPObservableBridgeSKIE
KMP-NativeCoroutines	KMPObservableBridgeNative
Callback, Combine, custom	KMPObservableBridge

SKIE in four steps

Declare current-value interoperability once:

import shared
import KMPObservableBridgeSKIE

extension SkieSwiftStateFlow: @retroactive KMPValueProperty {}

Select observable fields beside the feature:

@KMPObservable(
    ProfileViewModel.self,
    fields: \.profileState
)
extension ProfileViewModel: @retroactive KMPStaticallyObservable {}

Own the ViewModel:

@KMPStateObject
private var profile = ProfileViewModel()

Render a projected current value and call actions on the original model:

Text($profile.profileState.title)

Button("Retry") {
    profile.retry()
}

A writable Kotlin export produces a binding:

TextField("Search", text: $profile.searchText)

Ownership

• KMPStateObject owns a model for one SwiftUI identity.
• KMPObservedObject observes a model owned elsewhere.
• KMPEnvironmentObject consumes an existing projected store.
• Only an owning wrapper may dispose a Kotlin model.
