A simple way of organizing your app analytics events.

AnalyticsManager.swift

import Foundation
import Firebase // This can be changed by any other analytics library.

class AnalyticsManager{
    
    /// Unique instance of EventManager (SINGLETON)
    static var shared: AnalyticsManager = AnalyticsManager()
    
    // Stored properties
    // This is the place where you can add variables that are changed in multiple views to use in your events
    
    
    fileprivate init(){}
    
    /// Logs an app event in the Analyitics Dashboard
    /// - Parameters:
    ///   - event: The event declared in the AnalyticsEvent enum with all its parameters.
    static func logEvent(_ event: AnalyticsEvent) {
//        #if !DEBUG /* Uncomment this if statement if you want that only the production app send events. */
        
            // This is the function that sends the events to the chosen library, change it as needed.
            Analytics.logEvent(event.name, parameters: event.parameters)
        
//        #endif
    }
    
}

/// All events and its parameters
enum AnalyticsEvent {
//    Examples
//    case ButtonTapped
//    case FormSent(number: Int, color: String)
}

extension AnalyticsEvent{
    /// The name sent to the Analyitics Dashboard
    var name: String {
        switch self {
//        Examples
//            case .ButtonTapped:
//                return "button_tapped"
//
//            case .FormSent:
//                return "form_sent"
        }
    }
}

extension AnalyticsEvent{
    /// The parameters dictionary sent to the Analyitics Dashboard
    var parameters: [String : Any]? {
        switch self {
//            Examples
//            case .FormSent(let number, let color):
//                return ["Number" : number, "Color" : color]
                    
            default:
                return nil
