I've been learning about the new data flow architecture announced at WWDC 2023! I am currently trying to figure out how to create a user class which will hold my data regarding the following:


• Amount of bottles I would like to drink every day.

• Daily streak record

I'm finding the relationship between Swift's front end and back end quite tricky to work through, but I'm just trying to persevere step by step before I launch into how to handle notifications based on bottle size and daily goal.


Having seen some tutorials which explained the old way of handling State, Environment and Observable objects, I think learning the new Observation  way is definitely the easier way, but more importantly, I'm sure this is going to become industry standard over the years.

Happy Holidays!

It's now Boxing Day 2023, and in between prepping the turkey n tahteeers, I've thrown together a little Christmassy Swift Joy.

I've created a Christmas tree which lights up upon pressing the Merry Christmas button. Initially I've tried to play around with the new animated SF Symbols but I boiled it down to some plain and simple ForEach structure in SwiftUI.

I've played around with the size of the SF Symbol, to figure out how many rows I can get away with, making me land on 8. So I went ahead and created the following:

ForEach(0..<(row + 2), id: \.self) { item in

BaubleView(animationsRunning: $animationsRunning, availableColors: availableColors)

@StateprivatevaranimationsRunning = false

let availableColors: [Color] = [.red, .green, .blue, .orange, .purple]

.symbolEffect(.bounce, value: animationsRunning)

Image(systemName: "rectangle.portrait.fill")

Image(systemName: isFilled ? "circle.fill" : "circle")

.onReceive(Timer.publish(every: 0.5, on: .main, in: .common).autoconnect()) { _ in

color = availableColors.randomElement() ?? .green
