Mavis Source Code
Mavis was originally developed for MacOS as this was the most available and capable platform for the intended user.
Later, as needs changed, Mavis was rewritten in Swift/SwiftUI for deploy to iOS to facilitate using an iPad with a wireless QWERTY keyboard.
The MacOS version was kept separate as SwiftUI was very buggy when deployed to the desktop and did not meet our bar for reliability and ease-of-use.
In most cases, the programs use identical config files. The capabilities are similar, but not identical due to the variation in the underlying platforms.
We want to support your tinkering and experiments as best we can. We are also open to incorporating changes and republishing the applications to the AppStore.
