Creating a macOS “About” screen the SwiftUI way

If you’re creating a macOS app, the About screen is that place where you get to “sign” your work. It is also the place where most developers will link to their personal web, thank contributors, etc.  For me, it’s one of the areas I work on last… When I get to it, it always feels great.  …

Identifying combinations of dates in text using regex

For the upcoming app I’m working on I need a way to easily detect dates the user may have typed at the end of a line. It was time to re-visit old faithful regex.  After lots of readings and tests I ended up settling on this beauty:       “.*[0-9]{2}/[0-9]{2}” Here’s what it does: The …
