iOS 14 Publisher Guide


The intention of this guide is to help publishers streamline changes coming with Apple’s release of iOS 14.

Fyber has compiled a checklist of steps we recommend publishers take, to prepare for the release of iOS 14 for compatibility with Fyber’s SDK and app install attribution with Apple’s SKAdNetwork following an expected decrease in available IDFAs.

Publisher Checklist

Update to Fyber iOS 14 SDK

  • Please upgrade to Fyber's latest iOS SDK that includes major upgrades including support for Xcode12, iOS 14 and SKAdNetwork for app installs. Note: iOS 7.7.1 is the first SDK version with support.
  • Refer to our iOS Changelog and download our SDKs from Fyber’s UI or Cocoapods
  • Assist buyers in accessing IDFVs before IDFAs are deprecated with the release of iOS to be prepared for the post-IDFA reality

Incorporate SKAdNetwork IDs into Info.plist


SKAdNetwork IDs are case sensitive, and should be all lower case, according to Apple documentation.

To participate in install validation for Apple's SKAdNetwork the source app must include ad networks’ IDs in each apps’ Info.plist.

Programmatic ad buying uses the following framework for SKAdNetwork:

  • Fyber's publishers are considered source apps under the SKAdNetwork spec
  • Fyber's Demand Partners register and receive ad network IDs from Apple. Each Demand Partner running app install validation on Fyber Marketplace will have at least one SKAdNetwork ad network ID

Implement all recommended network_ids from Fyber’s SKAdNetwork list, available in JSON and XML format. The repo is updated regularly, so we always encourage taking the latest version before publishing a new app version to the App Store. Omitting an ID means preventing SKAdNetwork app install measurement for that entity buying on your inventory.

Unify your own developer user IDs to represent users across apps

  • While buyers are expected to use IDFV for frequency capping, Fyber recommends having an available fallback based on the publisher’s own user identifiers

Should I start using the permission-to-track pop up?
  • If requestTrackingAuthorization(completionHandler:) is called, an app-tracking authorization request will be presented to the end user, and they will be able to disable tracking and the IDFA will be zeroed.
  • In order to maximize Q4 revenue, we discourage publishers from showing the permission-to-track pop up, so that access to IDFA is maximized.
Is IDFV access impacted by Apple’s September 3rd announcement?
  • The ID for Vendors is always accessible to Fyber Marketplace SDK. No special publisher configurations are needed to collect this data.
Does Apple’s deprecation of the isAdvertisingTrackingEnabled property impact Fyber’s ability to collect IDFA, since isAdvertisingTrackingEnabled always returns ‘no’ under iOS 14?
There is no impact on Marketplace SDK’s ability to collect the IDFA. Please note, if a user enabled Limited Ad Tracking in pre-iOS 14, the IDFA will be zeroed out until user authorization is given.
Should I still implement SKAdNetwork ID’s in my apps info.plists even though consent to track was delayed by Apple?
Yes. We encourage all publishers to implement Fyber’s complete info.plist recommendation in your next app version release. Marketers are actively testing and implementing SKAdNetwork in Q3 2020 and usage is expected to be fully ramped up by Q4 2020. Your participation in the testing and implementation process is fundamental to enable privacy-aware app install tracking.
Where can I find your latest SKAdNetwork ID list and when was it last updated?
Fyber’s recommended list of SKAdNetwork ad network_ids is available in JSON and XML format. Each network_ids must be included on each app’s info.plist - so all Fyber buyers can continue to spend on your inventory. The repo was last updated on Sunday, October 4, 2020.
