iOS Cell Registration & Reusing with Swift Protocol Extensions and Generics

A common task when developing iOS apps is to register custom cell subclasses for both UITableView and UICollectionView. Well, that is if you don’t use Storyboards, of course.

Both UITableView and UICollectionView offer a similar API to register custom cell classes:

public func registerClass(cellClass: AnyClass?, forCellWithReuseIdentifier identifier: String)
public func registerNib(nib: UINib?, forCellWithReuseIdentifier identifier: String)

    var uncompressedPNGData: NSData      { return UIImagePNGRepresentation(self)!        }
    var highestQualityJPEGNSData: NSData { return UIImageJPEGRepresentation(self, 1.0)!  }
    var highQualityJPEGNSData: NSData    { return UIImageJPEGRepresentation(self, 0.75)! }
    var mediumQualityJPEGNSData: NSData  { return UIImageJPEGRepresentation(self, 0.5)!  }
    var lowQualityJPEGNSData: NSData     { return UIImageJPEGRepresentation(self, 0.25)! }
    var lowestQualityJPEGNSData:NSData   { return UIImageJPEGRepresentation(self, 0.0)!  }
