Add Day Button

Button

We'll add a button to create a new Day. For that, we'll add to the List a toolbar

/UI/DaysView.swift

List {
    // ...
}
// ...
.toolbar {
    ToolbarItem(placement: .bottomBar) {
        Button(action: {
            let day = Day.createDayWithHabitsInRealm(realm: realm)
            
            try? realm.write({
                $days.append(day)
            })
        }) {
            Image(systemName: "plus.circle.fill")
                .resizable()
                .frame(width: 50.0, height: 50.0)
        }.frame(maxWidth: .infinity, alignment: .trailing)
    }
}

To add a new object to our Database we use a Realm transaction realm.write, so we need to access our Realm in this class, so let's add a property:

/UI/DaysView.swift

    @Environment(\.realm) var realm
