IOS Plugin -- 2

We need to create an iOS version of our “openwith” plugin which replicates all the functionality of the Android plugin. The openwith plugin is loosely based on the cordova-plugin-openwith (https://github.com/j3k0/cordova-plugin-openwith) except that it adds persistence to the store of images and adds the ability to browse for images as well. The iOS plugin should be written in Swift and use no deprecated features of iOS. It should be able to automatically install itself with the “cordova plugin add” command via hooks and be able to be built on an M1 mac from the command line (no messing with XCode). I would expect some variables be required to be set when installing (similar as to what was required in the original openwith plugin but no other requirements). Included is the source for our openwith plugin, with a testbed that should run as explained in the README.md in openwith-demoapp directory.
