//
// In *Swift 3* we have to change `private` in favor of `fileprivate`
// Now `private` means **accesible under the scope**, usually {...} and
// `fileprivate` is accesible inside the file.

// MARK: - A Class  
//

internal class FilterView: UIView
{
	/// Elements returned after apply filter
	@IBOutlet fileprivate weak var labelQuantity: UILabel!

	...
}

//
// MARK: - Implements Protocol 
//

extension FilterView: SomeProtocol
{
	func apply(filter: String) -> Void
	{
		var quantity: Int = ...

		// Now compiles OK
		self.labelQuantity.text = "Founded \(quantity) element(s)."
