When I started trying to write a Mac app for the first time, I started out knowing what I wanted to achieve but not knowing how to go about it. I spent a lot of time googling for Mac development help and found very little of it. What i did find was mostly related to Objective-C and not Swift/SwiftUI.
So, I spent a lot of time going round in circles, extracting the bits that I thought relevant and heading down a lot of blind alleys.
This project is part of a series of development notes I want to write to document some of the stuff I learnt along the way. The note that goes with it can be found on my web site.
The File Dialogs note deals with the three basic file related dialogs.
While the first note deals with 'standard' or built-in file types, a second note expands on this topic to show how we can define our own file type handlers.
