1. Technical Requirements

The event collection API wrapper can be used with Swift 3.x and higher as well as with Objective-C. It has also been made compatible with certain dependency managers. The SDK can be used with the following:

  • Swift 3.x
  • Objective-C
  • Cocoapods
  • Use the Xcode project directly in the project

Demo projects: Please check the demo projects to see how to implement the SDK, set it up, create an event and send it to the backend. There is one demo project for Objective-C and another for Swift based implementations.

To embed the D2DEventCollectionKit, the project needs to have at least the following two build configurations: a.) Debug and b.) Release. More can be added if needed but at least these two should be present and used.

Build configurations on a project level
Link Binary

2. Setup

Choose a way to integrate the SDK into a project.

2.1 CocoaPods

CocoaPods is a dependency manager for Cocoa projects. It can be installed with the following command:

$ gem install cocoapods

To integrate the D2DEventCollectionKit into Xcode projects using CocoaPods, specify it in the Podfile:

source ''
platform :ios, '10.0'

target '<Your Target Name>' do
    pod 'D2DEventCollectionKit', '~> 0.1.1'

Then run the following command:

$ pod install

2.2 Manual Setup

To use the SDK without any dependency manager, drag the D2DEventCollectionKit.xcodeproj file into the project requiring the provided functionality. Go to the project settings and set the Target Dependency, Link Binary with Libraries and Framework Path Mapping as shown in the images below. Set these settings for all the targets being used.

Embedded Frameworks
Embed Frameworks

In Build Settings add (by using the + symbol on top) a set of user-defined variables and name them FRAMEWORK_PATH_MAPPING as shown in the example below. On the right side, the given build configurations can be used for mapping: Release and Debug.

Framework Path Mapping
Target Dependency

The right side shows the build configurations. These need to be mapped one by one to the predefined ones used by the SDK.

This step is recommended if the project’s environment variables are not using the Xcode defaults. If the project is running in Xcode’s predefined settings, nothing else is needed. NOTE: If multiple separate targets are being used, each setting must be specified on a per target level.

Once this is done, add the following variable for the mapping: Framework Search Path, and add the following entry:


Now go to ApplicationDelegate and add the module import statement import D2DEventCollectionKit. And that’s it.

Happy integrating!

3. Guide

The SDK will be available to use after it has been integrated with a compatible dependency manager. Setting it up is fairly straightforward. The same applies for the use of the SDK when using Objective-C. The D2DEventCollectionKitDemoObjc demo shows the integration process for Objective-C.


Implement the following in the application delegate:

 EventCollectionKit.register(applicationToken: "YOUR_APP_TOKEN_GOES_HERE",
                             applicationName: "Your application name",
                             applicationVersion: "1.0")

Following this step, debug output can be enabled/disabled. The debug output is disabled by default.

EventCollectionKit.enable(logging: true)

Create Events

Creating and sending an event is simple. To create an event for a route with the search action, use the convenient method on the TripEvent object. As shown in the example below.

Note: To be as accurate as possible, it is encouraged to provide coordinate data for latitude and longitude for the tracking. If concrete data for the 2 fields cannot be provided, enter 0.0 for each field and specify the address fields.

let tripSearchEvent  = TripEvent.tripSearchEvent(modesOfTransportation:[.train, .taxi],
                                                 departureTime: Date(),
                                                 originLatitude: 52.5230554,
                                                 originLongitude: 13.4122575,
                                                 originName: "Alexanderplatz",
                                                 originStreet: "Alexanderplatz",
                                                 originCity: "Berlin",
                                                 originPostalCode: "10119",
                                                 originCountry: "Germany",
                                                 arrivalTime: nil,
                                                 destinationLatitude: 52.5300641,
                                                 destinationLongitude: 13.4008385,
                                                 destinationName: "Door2Door HQ",
                                                 destinationStreet: "Torstrasse 109",
                                                 destinationCity: "Berlin",
                                                 destinationPostalCode: "10178",
                                                 destinationCountry: "Germany")

Sending events

After an event has been created, it is required to be sent using the EventCollectionKit send: function. That’s it. A list of events and parameter definitions can be found in the SDK itself or in the Reference section.

    EventCollectionKit.send(event: tripSearchEvent)

4. Reference

To make the SDK as easy to use as possible, the possible event types have been mapped to class functions of type TripEvent. A TripEvent can have multiple actions attached to it which defines the state for a trip. The list below shows the existing actions and their corresponding class functions for convenience.

Since the SDK supports Swift and Objective-C, two class functions per event will be implemented. One for Swift and one for Objective-C. When using Swift either one can be potentially chosen, however it is encouraged to use the function with the typed signature where the modesOfTransportation is of type [ModesOfTransportation]. The Objective-C implementation uses the signature modesOfTransportation with its type [NSNumber].

The ModesOfTransportation Swift enum defines the available modes of transportation and can be mapped into values from 0 - 8. These should be used as NSNumbers if the SDK is being used in Objective-C.

For example in Swift would map to the NSNumber @(ModesOfTransportationTaxi) using Objective-C.

public enum ModesOfTransportation: Int {
    case train // 0
    case walk // 1
    case publicTransport // 2
    case carSharing // 3
    case bikeSharing // 4
    case taxi // 5
    case privateBike // 6
    case rideSharing // 7
    case other // 8

The corresponding method signatures for TripEvent events can be found at Source/Events/Trip in the project.
