I've added CombineCocoa as an SPM dependency to an app being developed in Xcode 12 that supports iOS 13+.

When I add "import CombineCocoa" to a table view cell, it is highlighted in red and says "Missing required module 'Runtime'"

This PR adds support for a UITextView.valuePublisher publisher based on the one in RxCocoa and NSTextStorage (based on @jdisho's delegate proxy support).

Closes #19

Describe the bug I get an error while trying to upload a binary to Testflight

The app references non-public selectors in Payload/XXX.app/Frameworks/CombineCocoa.framework/CombineCocoa: handleEvent

To Reproduce Steps to reproduce the behavior:

1. Include CombineCocoa (using cocoapods in my case)
2. Archive and upload to Testflight

Expected behavior No error when distributing

Device:

• XCode 14.0.1
• CombineCocoa version 0.4.0

It seems that a delegate proxy can only be used on one item of its kind at a time.

For example in this screen, there are two view controllers, both have a UISearchBar. The one in the main view controller works completely fine, but the one on the half-modal (that has focus) doesn't do anything, none of the new publishers (for example searchBar.textDidChangePublisher) fire. Until I remove the delegate publishers from the other search bar, and then it works in the modal.

I am not sure if this extension is relevant to this lib, but is worth trying 😊

1. Creating contentOffsetPublisher just because of contentOffset in RxCocoa
2. Creating reachedBottomPublisher(offset:), which is a publisher, emitting if the bottom of the UIScrollView is reached. Similar to what we have in RxSwiftExt

For some reason it can be built separately, but building it as a dependency fails

Also, I don't want to be toxic, but I'd like to mention that this indentation

public init(
    control: Control,
    events: Control.Event
) {
    self.control = control
    self.controlEvents = events
}

looks more native to Combine, SwiftUI and Swift in general than this

public init(control: Control,
            events: Control.Event) {
    self.control = control
    self.controlEvents = events
}

which is more like objc indentation, and it makes me sad 🥲 maybe you should update your styleguides 😅

There seem to be a lot of changes in CombineCocoa.xcodeproj, maybe we're having an Xcode version mismatch or something? Feel free to take only UISearchBar+Combine.swift.

I'm trying to add some publishers to UISearchBarDelegate like this:

extension UISearchBar {
  var searchBarSearchButtonClicked: AnyPublisher<UISearchBar, Never> {
    let selector = #selector(UISearchBarDelegate.searchBarSearchButtonClicked(_:))

    return delegateProxy
      .interceptSelectorPublisher(selector)
      .map { $0[1] as! UISearchBar }
      .eraseToAnyPublisher()
  }

  private var delegateProxy: UISearchBarDelegateProxy {
      .createDelegateProxy(for: self)
  }
}

private class UISearchBarDelegateProxy: DelegateProxy, UISearchBarDelegate, DelegateProxyType {
  func setDelegate(to object: UISearchBar) {
    object.delegate = self
  }
}

Sadly I am getting two compiler errors:

'interceptSelectorPublisher' is inaccessible due to 'internal' protection level

and

Cannot inherit from non-open class 'DelegateProxy' outside of its defining module

Have you considered adding a publisher for gesture recognisers? Would be neat.

I’m happy to have a look at adding myself, just wanted to raise the issue to track.

Fixes: https://github.com/CombineCommunity/CombineCocoa/issues/56

Applying the same fix as used by the Realm project. Its not pretty but it does the job to maintain compatibility with iOS 10

Xcode 13 beta 3 added a swiftinterface file for armv7 Combine which makes canImport(Combine) return true, but the swiftinterface file doesn't actually compile (and no armv7 devices can run OS versions with Combine). Work around this by replacing the canImport(Combine) checks with a define we manually set when building for armv7.

Describe the bug When we try to archive a project which has CombineCocoa as a dependency, the archive fails. The following error is generated. Instance method 'subscribe(on:options:)' requires that 'DispatchQueue' conform to 'Scheduler' To Reproduce Steps to reproduce the behavior:

1. Add CombineCocoa as a dependency
2. Archive a project

Expected behavior The archive should be generated

Actual behavior Getting the error Instance method 'subscribe(on:options:)' requires that 'DispatchQueue' conform to 'Scheduler'

Fixes #81 by supporting forwarding delegate method calls similar to RxCocoa's setDelegate.

RxCocoa setDelegate example. https://github.com/ReactiveX/RxSwift/blob/1a1fa37b0d08e0f99ffa41f98f340e8bc60c35c4/RxExample/RxExample/Examples/SimpleTableViewExampleSectioned/SimpleTableViewExampleSectionedViewController.swift#L68

Describe the bug tableView(_:viewForHeaderInSection:) delegate method cannot be used when using tableView.didEndScrollingAnimationPublisher.

To Reproduce

class MyViewController: UIViewController {
    @IBOutlet private weak var tableView: UITableView!

    override func viewDidLoad() {
        super.viewDidLoad()
        
        tableView.didEndScrollingAnimationPublisher
            .sink { print("didEndScrollingAnimation") }
    }
}

extension MyViewController: UITableViewDelegate {
    func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
        // return my header view
    }
}

MyViewController is configured as a delegate of tableView in a storyboard.

Expected behavior tableView(_:viewForHeaderInSection:) is called

Device:

• Device: iPhone 14
• OS: iOS 16
• 0.4.1

Additional context RxCocoa supports this by calling tableView.rx.setDelegate(viewController).

UICollctionView did not work as expected. When I use colltionView to listen to both didScollPublish and didSelectedItemPublisher, they will not work at the same time and the first declaration will not work.

Simple case is as follows:

// NotWork collectionView.didScrollPublisher.sink { [weak self] _ in OMPrint("didScroll NotWork!" ) } .store(in: &cancellables)

// Work collectionView. DidSelectItemPublisher. Sink {indexPath in OMPrint("didSelectItem Work!" ) } .store(in: &cancellables)

Bumps tzinfo from 1.2.7 to 1.2.10.
