Testing

App styling

Detail view

Enable Video Trimming

• Start trim selection and End Trim selection. If we don't select values are nil

// MARK: - UIViewController: UIImagePickerControllerDelegate

  // If video was trimmed
            if let  startTrim = info[UIImagePickerController.InfoKey.init(rawValue: "_UIImagePickerControllerVideoEditingStart")] as! NSNumber?,
                let  endTrim = info[UIImagePickerController.InfoKey.init(rawValue: "_UIImagePickerControllerVideoEditingEnd")] as! NSNumber? {

• Gif refactoring.

• Gif class is now a wrapper class of Regift class. This means that we can create Gif directly with this class.

• App workflow

• We add a new textField to GifPreviewController .

1. Create a Gif without caption for showing in editor.
2. User can or not add caption in GifEditorController
3. Show the gif with caption overlay in GifPreviewController
4. When user CREATE or SHARE new gif will be created integrating caption.

• Edit saved videos

• Can't edit saved videos with image UIImagePickerController

The default camera interface supports editing of previously-saved movies. Editing involves trimming from the start or end of the movie, then saving the trimmed movie. To display an interface dedicated to movie editing, rather than one that also supports recording new movies, use the UIVideoEditorController class instead of this one. See UIVideoEditorController.
