Does anyone know if Apple plan a replacement? I was considering transferring from AdMob to iAd soon. If you have apps with iAd it seems you will need to re-code to another ad network.
"Correction, the iAd program as a whole is not shutting down. What is happening, is that the similarly-named iAd App Network, which allows developers to advertise their own apps through iAds, is going away."
From iTunes Connect, you can see message after login.
iAd App Network will be Discontinued
The iAd App Network will be discontinued as of June 30, 2016. Although we are no longer accepting new apps into the network, advertising campaigns may continue to run and you can still earn advertising revenue until June 30. If you’d like to continue promoting your apps through iAd until then, you can create a campaign using iAd Workbench. We will continue to keep you updated, but if you have any questions, contact us.
