I am working on displaying an iAd advertisement before a video plays, but the ad is not playing and I receive the following error:
Error Domain=ADErrorDomain Code=0
"The operation couldn’t be completed. (ADErrorDomain error 0.)"
There is no clear solution to me. So I have some doubt whether iAd is available in my region or not.
iAd is supported in India. You can see it included in the most recent list of iAd supported countries.
Your issue may be that you've set your iAd Testing Fill Rate to 0% on your development device.
Go to Settings>Developer>Fill Rate> and set it to 100%.
Also, make sure you're giving your advertisement time to load before trying to present it. Check out my implementations of iAd's Pre-Roll Video Ads here: Swift, Objective C.
