As iOS developer, here’s my humble list of what I hope to see today:
Fix UICollectionView’s, or everyone will be using PSTCollectionView (which is great by the way).
Fix iCloud. Because it just doesn’t work. A back-end as a service like Parse which worked natively with Core Data would be great.
Open Siri to third party developers to make it useful.
Last but not least, give me a damn Macbook Air Retina! It will not happen, I already know.
