Combine publisher bridges for UIKit

by iOS Example

CombineCocoa

CombineCocoa attempts to provide publishers for common UIKit controls so you can consume user interaction as Combine emissions and compose them into meaningful, logical publisher chains.

Note: This is still a primal version of this, with much more to be desired. I gladly accept PRs, ideas, opinions, or improvements. Thank you ! :)

Basic Examples

Check out the Example in the Example folder. Open the project in Xcode 11 and Swift Package Manager should automatically resolve the required dependencies.

Usage

tl;dr:

import Combine
import CombineCocoa

textField.textPublisher // AnyPublisher<String, Never>
segmented.selectedSegmentIndexPublisher // AnyPublisher<Int, Never>
slider.valuePublisher // AnyPublisher<Float, Never>
button.tapPublisher // AnyPublisher<Void, Never>
barButtonItem.tapPublisher // AnyPublisher<Void, Never>
swtch.isOnPublisher // AnyPublisher<Bool, Never>
stepper.valuePublisher // AnyPublisher<Double, Never>
datePicker.datePublisher // AnyPublisher<Date, Never>
refreshControl.isRefreshingPublisher // AnyPublisher<Bool, Never>
pageControl.currentPagePublisher // AnyPublisher<Int, Never>
tapGesture.tapPublisher // AnyPublisher<UITapGestureRecognizer, Never>
pinchGesture.pinchPublisher // AnyPublisher<UIPinchGestureRecognizer, Never>
rotationGesture.rotationPublisher // AnyPublisher<UIRotationGestureRecognizer, Never>
swipeGesture.swipePublisher // AnyPublisher<UISwipeGestureRecognizer, Never>
panGesture.panPublisher // AnyPublisher<UIPanGestureRecognizer, Never>
screenEdgePanGesture.screenEdgePanPublisher // AnyPublisher<UIScreenEdgePanGestureRecognizer, Never>
longPressGesture.longPressPublisher // AnyPublisher<UILongPressGestureRecognizer, Never>
scrollView.contentOffsetPublisher // AnyPublisher<CGPoint, Never>
scrollView.reachedBottomPublisher(offset:) // AnyPublisher<Void, Never>

Future ideas

  • Support non UIControl.Event-based publishers (e.g. delegates).
  • ... your ideas? :)
