📋 Requirements

Following are required for using CleverTap Geofence SDK -

• CleverTap iOS SDK version 3.9.0 or above
• Swift version 5.1 or above
• iOS version 10.0 or above
• Xcode 12 for targeting iOS 14.x.x
• CoreLocation iOS Framework

🎉 Installation

Via CocoaPods

CocoaPods is a dependency manager for iOS projects. To integrate CleverTap Geofence SDK into your Xcode project using CocoaPods, specify the following in your Podfile:

pod 'CleverTapGeofence'

You can refer to Demo Applications showcasing CocoaPods Installation.

For installing CleverTap Geofence via Carthage or Manually, check out the steps in Geofence Customization document.

🚀 Integration

CleverTap Geofence utilizes Core Location APIs to setup up Geofences Region monitoring. The CleverTap Geofence will NOT request Location permissions from the user. Location Permission has to requested by the app as deemed fit while onboarding the user to the app.

1. In Xcode, enable Location Updates in Background Modes for your App Target. You can enable this in Xcode by -

• Click on your AppTarget in Xcode Project Navigator
• Click on Signing & Capabilities tab
• Click on + Capability button
• Select the Background Modes option
• Enable Location Updates by selecting the checkbox

2. In your Info.plist file, add the following keys -

• NSLocationAlwaysAndWhenInUseUsageDescription also known as Privacy - Location Always and When In Use Usage Description This is a key that accepts a String description to be used by iOS while requesting Location permission from the user.

• NSLocationWhenInUseUsageDescription also known as Privacy - Location When In Use Usage Description This is a key that accepts a String description to be used by iOS while requesting Location permission from the user.

• UIBackgroundModes also known as Required background modes This is a key that accepts an Array of items. This should include the location also known as App registers for location updates item to enable Background Location monitoring.

For iOS 11 only: If your app targets iOS 11 then along with the above mentioned 3 Info.plist keys, the following key is also required. If your app target is iOS 12 or above, the following is not required -

• NSLocationAlwaysUsageDescription also know as Privacy - Location Always Usage Description This is a key that accepts a String description to be used by iOS while requesting Location permission from the user. Only required for iOS 11.

Following is an example of all the Info.plist keys in Source Code format -

<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
<string>App needs your location to provide enhanced features.</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>App needs your location to provide enhanced features.</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>App needs your location to provide enhanced features.</string>
<key>UIBackgroundModes</key>
<array>
  <string>location</string>
  <string>remote-notification</string>
  <string>fetch</string>
  <string>processing</string>
</array>

3. In your AppDelegate file, import the CleverTapGeofence module:

// Swift
import CleverTapGeofence

// Objective-C
@import CleverTapGeofence;

4. In your AppDelegate's application:didFinishLaunchingWithOptions: function, add the following the code snippet. Ensure that Geofence SDK initialization is done after CleverTap Main SDK initialization.

// Swift
CleverTapGeofence.monitor.start(didFinishLaunchingWithOptions: launchOptions)

// Objective-C
[[CleverTapGeofence monitor] startWithDidFinishLaunchingWithOptions:launchOptions];

5. CleverTap Geofence SDK requires location permission from users to provide the Geofencing capabilities. The App is expected to request Location permission from the user at an appropriate time. Once CleverTap Geofence SDK detects that Location permission has been given by the user, only then the module will start to perform its functions.

iOS 14 Update: If user has opted for reducedAccuracy option of the accuracyAuthorization settings then CleverTap Geofence will not work as expected since the app cannot reliably utilize Core Location's Region Monitoring APIs.

An example of how an app can request location permission is below:

// Swift
let locationManager = CLLocationManager()
locationManager.requestAlwaysAuthorization()

// Objective-C 
CLLocationManager *locationManager = [[CLLocationManager alloc] init];
[locationManager requestAlwaysAuthorization];

📖 Customization
