TargetClosure.swift

//
// TargetClosure is a bridge from closures to objc targets/selectors
// Create a TargetClosure with a closure and pass it as the target, then pass target.selector as the selector.
//
// Example:
//
// let target = TargetClosure { doYourThing() }
// oldSchoolFunction(target: target, action: target.selector)
//

public class TargetClosure {
  public let selector: Selector

  private let action: () -> Void

  init(_ closure: @escaping () -> Void) {
    selector = #selector(run)
    action = closure
  }

  @objc public func run() {
    action()
  }
}
