What about this

public class ScreenRecorder: NSObject, RPPreviewViewControllerDelegate {
    public typealias PreviewControllerFinishedAction = (activities: Set<String>?) -> ()
    public typealias RecorderStoppedAction = () -> ()

    var recorder = RPScreenRecorder.sharedRecorder()
    var preview: RPPreviewViewController?
    var activities: Set<String>?

    public var previewFinishedAction: PreviewControllerFinishedAction?
    public var recorderStoppedAction: RecorderStoppedAction?
    public var enableMicrophone = false

    public func start() {
        preview = nil
        recorder.startRecordingWithMicrophoneEnabled(enableMicrophone) { error in
            if error != nil {
                print("Start Recording Error: \(error?.localizedDescription)")
            }
        }
    }

    public func start(duration: Double) {
        start()
        delay(duration) {
            self.stop()
        }
    }


    public func stop() {
        recorder.stopRecordingWithHandler { previewViewController, error in
            self.preview = previewViewController
            self.preview?.previewControllerDelegate = self
            self.recorderStoppedAction?()
        }
    }

    public func showPreviewInController(controller: UIViewController) {
        guard let p = preview else {
            print("Recorder has no preview to show.")
            return
        }

        controller.presentViewController(p, animated: true, completion: nil)
    }

    public func previewController(previewController: RPPreviewViewController, didFinishWithActivityTypes activityTypes: Set<String>) {
        activities = activityTypes
    }

    public func previewControllerDidFinish(previewController: RPPreviewViewController) {
        previewFinishedAction?(activities: activities)
        preview?.parentViewController?.dismissViewControllerAnimated(true, completion: nil)
    }
}

Looks good. Only change would be to rename recorderStoppedAction to:

recordingEndedAction

I'm not a fan of:

recorder.recorder...

Nice trick with the parentViewController
