Appearance

Every aspect of swiftDialog's appearance can be modified.

At the most simple level you need only give swiftDialog a Title and a Message to display but there is more utility in modifying other aspects of the appearance:

Pass in an image resource to display as the swiftDialog icon, or use an app path or system preference bundle path and swiftDialog will extract the icon for display.
Add extra buttons. Change the text to say what you want. Wait for user input or automatically time out.
Use markdown in the message to add bold or italics or include URL links
Change the colour, size or even the font used in the Title and Message areas
Change the size of the swiftDialog window
Display Videos or Images either locally or pass in a URL
and lots more...
