iOS surveys installation

Install dependency

Required

Install via Swift Package Manager:

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

Or add PostHog to your Podfile:

Podfile
pod "PostHog", "~> 3.0"

Configure PostHog

Required

Initialize PostHog in your AppDelegate:

AppDelegate.swift
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_token>"
        let POSTHOG_HOST = "https://us.i.posthog.com"

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

        return true
    }
}

Send events

Recommended

Once installed, PostHog will automatically start capturing events. You can also manually send events to test your integration:

Swift
PostHogSDK.shared.capture("button_clicked", properties: ["button_name": "signup"])

Enable surveys in your configuration

Required

To enable surveys in your iOS app, enable surveys in your PostHog configuration:

AppDelegate.swift
let POSTHOG_API_KEY = "<ph_project_token>"
// 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) 

// Surveys require iOS 15.0 or later
if #available(iOS 15.0, *) {
    config.surveys = true
}

PostHogSDK.shared.setup(config)
