Provide apps with access to an advertising identifier and a flag indicating whether a device is using limited ad tracking.


Use the AdSupport framework if you are implementing a system to serve advertisements. The AdSupport framework provides the object your app will use to access an advertising identifier and opt-out flag to indicate devices using limited ad tracking.

If devices are not using limited ad tracking, you can use the advertising identifier for frequency capping, attribution, conversion events, estimating the number of unique users, advertising fraud detection, and debugging.
