@RxPublished is a drop-in replacement for Combine's @Published and is intended to be used in ObservableObject View Models. Under the hood it utilizes RxSwift instead of Combine, allowing pre-existing RxSwift code to be used more seamlessly in SwiftUI.
Its projected value (using $ operator like $example) provides access to an observable stream, mirroring the functionality of the stock @Published. Usage within SwiftUI Bindings also works as expected (like for TextField).
If your source of truth lives elsewhere, you can also bind to an external Observable.
Add the following to your Package.swift file:
.package(url: "https://github.com/dropbox/RxPublished.git", .upToNextMajor(from: "1.0.0")),@RxPublished private(set) var example: String = "hello world"Use the underscored accessor to bind to an Observable that lives elsewhere
@RxPublished private(set) var example: String = ""
init(someObservable: Observable<String>) {
someObservable.bind(to: _example)
}Observe value changes:
$example
.distinctUntilChanged()
.subscribe {
print("value changed: \($0)")
}
.disposed(by: disposeBag)Copyright (c) 2025 Dropbox, Inc.
