Quickly start up your iOS integration with Leanplum

This article is your first step to activating the Leanplum iOS SDK. Once completed, you will have access to all the goodness Leanplum provides. Follow the steps below.

STEP 1: Install the SDK

To install the Leanplum SDK there are two main options, downloading Cocoapods or through a manual setup.


Supports iOS 9.0 and above

A. Download Cocoapods and Add to Podfile (recommended)

  1. If you don't already have CocoaPods installed and a Podfile in your project, run the following script in Terminal
sudo gem install cocoapods
pod init
open -a Xcode Podfile
  1. Once downloaded, add the following to your Podfile
pod 'Leanplum-iOS-SDK', '<<LEANPLUM_IOS_SDK_VERSION>>'

# Uncomment one of the following for Location Services.
# pod 'Leanplum-iOS-Location', '<<LEANPLUM_IOS_SDK_VERSION>>'
# pod 'Leanplum-iOS-LocationAndBeacons', '<<LEANPLUM_IOS_SDK_VERSION>>'
  1. Finally run the below command to install the Leanplum SDK to your project
pod install

B. Manually Install iOS SDK

If you would rather like to manually install our iOS SDK, please use the following steps

  1. Visit and download the latest release of our SDK from Github

  2. Add the Leanplum.framwork to your embedded binaries in your project
    NOTE: If you require to use Location services on Leanplum, add LeanplumLocation.framework or LeanplumLocationAndBeacons.framework if you need iBeacon services. You can be downloaded at GitHub.

  1. Add the following Leanplum Frameworks to your project
    • CoreLocations.framework
    • CFNetwork.framework
    • SystemConfiguration.framework
    • Security.framework
    • AdSupport.framework
    • StoreKit.framework

STEP 2: Import Leanplum Into Your App Delegate

Below is sample code you can use in your App Delegate to get Leanplum started. For more on API Keys visit our article on our API keys.

import UIKit
    import AdSupport
import Leanplum

class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?

func application(application: UIApplication!, didFinishLaunchingWithOptions launchOptions: NSDictionary!) -> Bool {
  // You will find your API Keys at
  #if DEBUG
      withProductionKey: "YOUR_PRODUCTION_KEY")
  // Sets the app version, which otherwise defaults to
  // the build number (CFBundleVersion).

  // Starts a new session and updates the app content from Leanplum.

  return true
#import "AppDelegate.h"
#import <Leanplum/Leanplum.h>

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
  /// You will find your API Keys at
  #ifdef DEBUG
    [Leanplum setAppId:@"YOUR_APP_ID"
    [Leanplum setAppId:@"YOUR_APP_ID"

  // Optional: Tracks in-app purchases automatically as the "Purchase" event.
  // To require valid receipts upon purchase or change your reported
  // currency code from USD, update your app settings.
  // [Leanplum trackInAppPurchases];

  // Sets the app version, which otherwise defaults to
  // the build number (CFBundleVersion).
  [Leanplum setAppVersion:@"2.4.1"];

  // Starts a new session and updates the app content from Leanplum.
  [Leanplum start];
  return YES;


Setting AppIds from plist file

Starting from iOS SDK 3.1.0, we support the option to provide the AppId, Production, and Development keys in a plist file. If the keys are not set before calling Leanplum.start they are loaded from the Leanplum-Info.plist if such exists.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "">
<plist version="1.0">

The Environment key (ENV) value must be either development or production. The environment can also be changed using Leanplum setAppEnvironment method which accepts the same values.


Use Your Development Key Only During Your Development Phase

The Leanplum development key leverages open socket technology in our development pipeline for real-time previewing and analytics. This pipeline therefore cannot support a live production scale and any user data maybe lost as it is not captured in analytics.

Additionally for tighter security, make sure to remove your development key from your app delegate before submitting to the App Store.

STEP 3: Run Your Build

Build and run your app and see data start flowing into Leanplum. With your development key in your app delegate, you will be able to see all data flowing into Leanplum in our debugger. You can access our debugger dashboard at



App Version

The App Version that will be captured in Leanplum when running your build in iOS will default to the main bundle CFBundleVersion when called.

STEP 4: Register Your Test Device

Registering your device as a test device will allow you to preview your messages, variable changes, and any other Leanplum projects. Follow the below to register.

1. Enable the DEBUG preprocessor macro in your Build Settings

Registering a test device will allow you to test your messages, variable changes, and other Leanplum projects on a real device.

To register your device, first make sure you're in Debug mode. To ensure Debug mode is enabled, make sure the DEBUG preprocessor macro is set in Build Settings.
Apple Clang - Preprocessing -> Preprocessor Macros -> Debug. Set value to DEBUG=1.

Add DEBUG flag (Swift only)

In your Build Settings, add -D DEBUG to Debug mode in Other Swift Flags.

2. Register Your Device On the Test Devices Page

Visit and click on "Register test device" to register your device


STEP 5: Complete Your Integration (NEXT STEPS)

Success! You have now successfully installed the Leanplum iOS SDK and registered a test device for further testing. This is an exciting first step on the journey to full integration with Leanplum.
