Apple may not be on the friendliest terms with developers as compared to other companies, though they’ve been quite thoughtful lately. The official Apple Developer site is currently hosting the iAd Producer for developers who want to create content for iAds on the iOS platform.
Before iAd content is deployed to the iAd Network, iAd Producer tests it for common errors including incorrect page or component configurations, the size and type of image assets. One of the main elements is the Visual Designer that offers developers an overview of the structure and flow of the respective iAds depending on the selected iOS.
The iAd Producer is replete with other useful tools like pre-built animations, effects and a component library, page templates, simulator features and much more. It is currently downloadable through the Apple Developer website.
