A/B testing installation

A/B testing enables you to test the impact of product changes and understand how they affect your users' behaviour. For example:

• How changes to your onboarding flow affect your signup rate.
• If different designs of your app's dashboard increase user engagement and retention.
• The impact a free trial period versus money-back guarantee to determine which results in more customers.

A/B tests are also referred to as "experiments", and this is how we refer to them in the PostHog app.

To start using A/B tests, install PostHog with the library you want to run tests in (if you haven't already):

pod "PostHog", "~> 3.0"

dependencies: [
  .package(url: "https://github.com/PostHog/posthog-ios.git", from: "3.0.0")
],

.target(
    name: "myApp",
    dependencies: [.product(name: "PostHog", package: "posthog-ios")]),

import Foundation
import PostHog
import UIKit

class AppDelegate: NSObject, UIApplicationDelegate {
    func application(_: UIApplication, didFinishLaunchingWithOptions _: [UIApplication.LaunchOptionsKey: Any]? = nil) -> Bool {
        let POSTHOG_API_KEY = "<ph_project_api_key>"
        // usually 'https://us.i.posthog.com' or 'https://eu.i.posthog.com'
        let POSTHOG_HOST = "https://us.i.posthog.com"

        let config = PostHogConfig(apiKey: POSTHOG_API_KEY, host: POSTHOG_HOST) 
        PostHogSDK.shared.setup(config)

        return true
    }
}
