Q: Can I use Photoshop CS6?
A: No, you can't. Replia requires Photoshop CC 2014.
Q: Is the autolayout supported?
A: No, it isn't. Layout is exported as the AutoresizingMask. You can set the autolayout in the InterfaceBuilder of Xcode.
Q: Can I export as UITableViewController or UICollectionViewController?
A: No you can't. Replia exports the view controller as a UIViewController. However, Replia can export a specific layer as the custom UIView. You can edit the custom UIView to inherit a UITableViewCell or a UICollectionViewCell in Xcode.
