Big issue with the delegate proxies

[freak4pc]

Fixed in 0.3.0. Thanks @TTOzzi !

Definitely sounds like a bug. @jdisho let me know if you might have some time looking into this ?
Otherwise I'll try carving some time in a couple of days.

Weirdly enough I can't reproduce the problem with a minimal repro project, but it's definitely a problem with my project. Not sure what's going on here. I'll investigate more and report back, hopefully with a repro project.

Any chance you're accidentally also setting a regular delegate with the proxy? Perhaps in a storyboard or something ?

[kevinrenskers]

No. But I did manage to boil it down to this:

import UIKit
import Combine
import CombineCocoa

class SearchViewController: UIViewController {
  @IBOutlet var searchBar: UISearchBar!
  @IBOutlet var collectionView: UICollectionView!

  private var subscriptions = Set<AnyCancellable>()

  override func viewDidLoad() {
    super.viewDidLoad()

    searchBar.textDidChangePublisher
      .sink { print("Text changed: \($0)") }
      .store(in: &subscriptions)

    collectionView.didSelectItemPublisher
      .sink { print("Item selected: \($0)") }
      .store(in: &subscriptions)
  }
}

searchBar.textDidChangePublisher never fires, until you remove collectionView.didSelectItemPublisher.

Hey @freak4pc! Currently I'm in holidays and I will not be home until Sunday.

[freak4pc]

I'm pretty sure I know why this happens but will need to investigate.

[kevinrenskers]

I hope you can figure it out! Right now I have to rip out a whole bunch of delegate publishers from my app because yeah they're conflicting with each other. If there is anything I can do to help test a fix, let me know.
