Hello All, I hope my first post here finds everybody doing well. I wish to develop a simple app. I have some coding experience using other technologies. This would be my first iOS and MacOS app. I am asking for advice regarding the choice of tools and or technology. Here is what I think potential advice givers need to know: Motivation is to keep evil coworkers from messing with my Mac when I step away from, (often), my desk In order to thwart their machinations, I have set my Mac to lock after a very short period of inactivity - this is often a pain as I am sitting at my desk when the Mac locks I wear a fairly new iWatch and am using an M2 Macbook Air I want an app that keeps my Mac from locking when I am nearby I want an agent that runs on my Mac that listens for pings from my iWatch I want an app for my iWatch that pings my Mac It would be nice to be able to set the radius of the "nearby zone" and ping rate A ping would interact with my agent so as to keep my Mac from locking If no ping, Mac locks per whatever time-out setting I have on my Mac I know, I know. I could just use some key combos. No need to point out the obvious way of dealing with the bozos, (we have fun), that I work with. Stymying them in this manner would enhance my happiness. I just want a bit of advice on the appropriate way of going about this. Hopefully, anything I learn might someday be applied to the development of other simple apps. Thanks for any thoughts offered!
