AdAttributionKit

Privacy-preserving ad attribution for iOS 17.4+. AdAttributionKit enables ad networks and advertisers to measure app installs and re-engagements across the App Store and alternative marketplaces without disclosing user-level identity.

Three distinct roles participate in attribution:

• Ad Network: Signs ad impressions with JWS and receives cryptographically validated postbacks.
• Publisher App: Hosts and renders ads using UIEventAttributionView or StoreKit overlays.
• Advertised App: Registers conversions, updates conversion values, and receives copy postbacks.
