I think I found a better way of doing this. Rather than keeping days as a computed property, I changed it to @State and moved its computation implementation to the View's top level ZStack's onAppear. It was most certainly being called somewhere in my code again and again. But I only needed to calculate days only once to begin with so there was no point in making it a computed property in the first place.

Hi @Claude31, heres the code for checkbox where days is actually being used: var checkboxes: some View {     HStack {       if days.count > 0 {         ForEach(days.reversed(), id: \.id) {day in           VStack() {             Text(day.dayValue)               .fontWeight(.light)               .font(.callout)             if !day.checked && !day.passed {               Image(systemName: "circle")                 .resizable()                 .frame(width: daysCircleRadius, height: daysCircleRadius)             } else if !day.checked && day.passed {               Image(systemName: "multiply.circle")                 .resizable()                 .frame(width: daysCircleRadius, height: daysCircleRadius)             } else {                 Image(systemName: "checkmark.circle")                   .resizable()                   .frame(width: daysCircleRadius, height: daysCircleRadius)             }         }       }     }   } When I comment out the ForEach in here, the app works perfectly, without showing the checkboxes
