SwiftListener

EXAMPLE - Segue Listening. Easy way to pass data to segue's destination controller

• Just set "BaseSegue" as a class of your segue

• In your ViewController add listener:

    addSegueListener() {
        (vc: SecondViewController) in
        
        vc.view.backgroundColor = .red
    }
  

Where SecondViewController is a segue's destination.

EXAMPLE - TableView Data binding

Just add a couple of "set" methods to bind data and delegate your TableView

    tableView.set(onHeightForRowAt: {
            tableView, indexPath in

            return 40
    })

    tableView.set(onCellAtIndexPath: {
        tableView, indexPath in

        return UITableViewCell()
    })

    tableView.set(onNumberOfSections: {
        tableView in            
        return 1
    })

    tableView.set(onNumberOfRowsInSection: {
        tableView, section in

        return modelsArray.count
    }
    )

    tableView.set(onDidSelectRowAt: { [weak self]
        tableView, indexPath in

        guard self != nil else {
            return
        }
    }
    )

EXAMPLE - Event dispatching and subscribing

    class MyClass: NSObject {
        static let onEvent = "onEvent"

        func testDispatchNoData() {
            //Dispatch event
            dispatchEvent(with: MyClass.onEvent)
        }

        func testDispatchWithData() {

            //Dispatch event with custom data

            let event = Event(name: MyClass.onEvent)
            event.data = "I'm String Data!"
            dispatchEvent(event)
        }

        func testDispatchResult() {
            if let intValue = dispatchEvent(with: MyClass.onEvent) {
                print("I'm Int Value! \(intValue)")
            }
        }

    }

    //////
    let object = MyClass()

    //Just add event listener for any class
    object.addEventListener(eventName: MyClass.onEvent, listeningObject: self) {
        event in

        if let data = event.data {
            print(data)
        } else {
            print("hello, data is nil!")
        }

        return 10000000
    }

    // do smth with your class

    object.testDispatchNoData()
    object.testDispatchWithData()
    object.testDispatchResult()

THE OUTPUT IS

hello, data is nil!

I'm String Data!

hello, data is nil!

I'm Int Value! 10000000
