Quick Start

Getting Started / iOS

Check our public sample application for an actual implementation of the snippets below and how they can be utilized.

Overall Code

A quick start snippet will look something like this in your app's willFinishLaunchWithOptions:

import DolphinMoveSDK

func application(_ application: UIApplication, willFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]? = nil) -> Bool {
 
    MoveSDK.shared.setSDKStateListener { sdkState in
            switch state {
            case .uninitialized:
                print("/* SDK uninitialized*/")
                break
            case .ready:
                print("/* SDK initialised and ready to start the service*/")
                break
            case .running:
                print("/* SDK Started Detection*/")
                break
            }
    }
    
    MoveSDK.shared.setAuthStateUpdateListener { authState in  ... }    
    MoveSDK.shared.setTripStateListener       { tripState in ... }
    MoveSDK.shared.setServiceFailureListener  { failures in ... }
    MoveSDK.shared.setServiceWarningListener  { warnings in ... }

    MoveSDK.shared.initialize(launchOptions: launchOptions)
}

This snippet assumes that the required configurations and permissions are already setup to work. Check the permissions handling section for more details.

SDK Authorization and Setup

Users will need to be authenticated. This authentication will persist until shutdown is called. It will persist over the termination of the app. The configuration to enable functionality is passed here. startAutomaticDetection will start the services. This too will persist and services will automatically start when launching the app from the background.

The authentication object is constructed with tokens that need to be acquired from the backend (either from the SDK backend directly, or via your product backend). See MOVE Backend.

import DolphinMoveSDK

// Response from the API Request.
// {
//  "authCode": "string"
// }

let authCode = ...

let sdkConfig = MoveConfig(
                detectionService: [
                .driving([.drivingBehavior, .distractionFreeDriving, .deviceDiscovery]),
                .walking([.location]), .cycling, .places,
                .publicTransport,
                .pointsOfInterest,
                .assistanceCall,
                .automaticImpactDetection
])

MoveSDK.shared.setup(authCode: authCode, config: config) { status in
    ...
}

...

MoveSDK.shared.startAutomaticDetection()
...

Authentication Invalidation

The host app is expected to monitor MoveAuthState updates viaauthStateChangeListener(iOS) API and handle those changes accordingly.

Check Authentication updates and expiry for more details about authentication expiry and renewal.

An auth state listener must be implemented to handle user invalidation, which can happen due to a user being blocked or having multiple conflicting installations with the same user.

import DolphinMoveSDK

func application(_ application: UIApplication, willFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]? = nil) -> Bool {

    ...

    MoveSDK.shared.setAuthStateUpdateListener { state in
        switch state {
        case .invalid:
            MoveSDK.shared.shutdown()
        }
    }

    MoveSDK.shared.initialize(launchOptions: launchOptions)

...

SDK State

The host app is expected to set its SDKStateListener before initializing the SDK to intercept the MoveSDKState changes.

The provided block could then start the SDK when MoveSDKState is ready or handle errors if occurred. The provided block could look something like this:

MoveSDK.shared.setSDKStateListener { state in
    switch state {
    case .uninitialized:
        /* SDK uninitialized*/
        break
    case .ready:
        /* SDK initialised and ready to start the service*/
        break
    case .running:
        /* SDK Started Detection*/
        break
    }
}

SDK Initialization

TheinitializationAPI must be executed beforedidFinishLaunchingWithOptionsreturns. We recommend calling it inwillFinishLaunchingWithOptions. Exceptions might apply, where the SDK is not initialized on app launch. First initialization is a good example, where the app would only initialize the SDK after onboarding the user and requesting permissions. Check Initialization Timing for more details about the importance of adequately initializing the SDK.

MoveSDK.shared.initialize(launchOptions: launchOptions)

Warnings and Errors

When services are not running properly because they are missing permissions or are not authorized on the backend, warnings or errors will be reported in the corresponding listeners.

MoveSDK.shared.setServiceFailureListener { failures in
    for failure in failures {
        /* a list of MoveServiceFailure objects */
        switch failure.reason {
	case .unauthorized:
	    /* a service is not configured on the backend */
	    break
	case let .missingPermission(permissions):
	    /* a required permission is missing */
	    break
        }
    }
}

MoveSDK.shared.setServiceWarningListener { warnings in
    for warning in warnings {
        /* a list of MoveServiceWarning objects */
        switch warning.reason {
	case let .missingPermission(permissions):
	    /* an optional permission is not provided, data collection will be reduced */
	    break
        }
    }
}
