I am developing my first mobile application and hope to submit it to Apple soon for approval.

I have incorporated iAd banners and interstitials in my app.

But I am confused about the future of iAds and it's application to app publishers/developers.

Apple announced (Jan 15, 2016):

> 
> iAd App Network will be Discontinued 
>

> The iAd App Network will be discontinued as of June 30, 2016. Although

>  We will continue to keep you updated, but if you have any questions,
>  contact us.
>

Which seems pretty plain and simple - no more iAd integration for new apps that are not currently in the iAd program.

Other new sources (unofficial to Apple themselves) quote the development as a good thing for mobile developers in general. Although exactly how this is good for mobile app developers escapes me.

Add the fact that there are still so many active questions, answers and dialogues at StackOverflow surrounding iAds and their implementation in apps currently under development.

If iAds is closing down, why are people still integrating them into their current projects (for apps not yet released)? 

Can anyone please explain this to me?
