Energy Bar is very simple message bar that get to user's response.

pod 'EnergyBar'

class AppDelegate: UIResponder, UIApplicationDelegate {
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        
        let energyBar = EnergyBar(delegate: self)
        
        return true
    }
}

extension AppDelegate: EnergyBarDelegate {
    func buttonTap(eventID: String, tag: Int) {
        //handle your event
    }
}

try? energyBar.show(eventID:messageLabel:buttons:size:)

energyBar.bringEnergyBarToFront()

• Make energyBar singleton like App.energyBar
• AppDelegate class must have EnergyBarDelegate
• Make custom events use enum like...

  enum EnergyBarEvents: String {
      case doSomething = "doSomethingEvent"
  }
  

  and... pass enum's rawValue to show method like...

  eventID: EnergyBarEvents.doSomething.rawValue
  

  then EnergyBarDelegate returns eventID. and handle event like...

  if let event = EnergyBarEvents(rawValue: eventID) {
      switch event {
      case .doSomething:
          //handle event
      }
  }
