How to create a calendar in SwiftUI with Grid Layout

So I’ve been building this productivity app because well, I’m a nerd and like doing things like that. In my pursuit I had to create a calendar view like the one above so a user can see how many days they’ve consecutively accomplished some task.

In my pursuit I didn’t find any pure SwiftUI resources but did find something about the Grid Layout which allows you to lay your views out in a grid format instead of just stacking vertically, horizontally, and overlaying views (referring to VStack, HStack, and ZStack). Turns out you can create a calendar pretty easily with this grid layout. Specifically, you want to utilize LazyVGrid and pass in 7 columns (or less if you want) to represent each row and compute 31 different views with a ForEach loop. The grid will handle the wrap around for you automatically (thank you 🍎).

• LazyVGrid creates a grid for you with a specified number of columns, for us that’s 7 as a calendar usually (in the U.S.) has 7 days per row
• ForEach computes views based on some data and for us that’s the number of days for a particular month (here I assume 31)

The code below will render the screenshot above. Of course, you can manipulate this as you wish – it is free for the beautiful programmers of the SwiftUI community to use ^_^.

Happy coding folks!
