I am almost done with this view, but am stuck on the final Total Calories row at the bottom. I cannot make it sum the protein/carb/fat calorie numbers. I believe this is because they are defined and changed out of scope (in the other HStack), so I tried to define the GramTotals at the top of the struct.
That got rid of the errors, but it seems the Total Calories HStack will not recognize the changes being made to the values in the other HStack. Any ideas for how to fix this? I'll owe you one!
Full Code is below:
import SwiftUI
struct ContentView: View {
init() { // this can be done in `onAppear` modifier if you need to restore the appereance later on `onDisappear`
UITableView.appearance().contentInset.top = -35
