Sift iOS SDK

Integration guide

Here is how to integrate with Sift iOS SDK into your Objective-C iOS app project (for Swift projects the steps are pretty similar).

Installing the library

You may get the SDK into your iOS project through either CocoaPods or Carthage.

Through CocoaPods:

  • Add this to your Podfile: pod 'Sift' (this uses the latest version).

  • Run pod install.

Through Carthage:

  • Add this to your Cartfile: github "SiftScience/sift-ios" (this uses the latest version).

  • Run carthage update.

Recommended steps:

  • Add this to your application's Info.plist file:


    We detect jailbroken devices with various signals and one of them is whether Cydia is installed. Since iOS 9, you have to whitelist URL schemes you would like to check, and this just adds Cydia to the list.

Initializing the library

The SDK works in the background and so you have to initialize it when your app starts. It usually makes most sense to initialize the SDK in application:didFinishLaunchingWithOptions:.

Here is what you would do within AppDelegate.m:

  • Add #import "Sift/Sift.h".

  • Add the application:didFinishLaunchingWithOptions: instance method if it doesn't exist, and insert this code snippet (replacing the placeholder strings with your Sift account credentials):

    Sift *sift = [Sift sharedInstance];
    [sift setAccountId:@"YOUR_ACCOUNT_ID"];
    [sift setBeaconKey:@"YOUR_JAVASCRIPT_SNIPPET_KEY"];
  • (Recommended) If your app uses motion sensors (accelerometer, gyro, or magnetometer), and you want to send motion data to Sift, add this line:

    [sift setAllowUsingMotionSensors:YES];

    This will enable the SDK to occasionally collect motion data in the background.

  • If your app uses user location data but you do not want send it to Sift, add this line:

    [sift setDisallowCollectingLocationData:YES];

Tracking users

Sift needs the user ID to track the user using this app. Once the user ID is available (for example, after user has logged in), please set the user ID:

[[Sift sharedInstance] setUserId:@"USER_ID"];

If a user logs out, unset the user ID by invoking:

[[Sift sharedInstance] unsetUserId];
