Instance Property


The item to preview.


var previewItem: QLPreviewItem! { get set }


Any item that you wish to preview must conform to the QLPreviewItem protocol. When you set this property, the QLPreviewView will load the preview asynchronously. Due to this asynchronous behavior, you can’t assume that the preview is ready immediately after assigning it to this property.
