ios – Passing Nilable to a Sheet always considers is as null the first time

I have a nilable variable, targetLast5Day, and I’m passing it to a sheetView I’m displaying. I’m declaring the variable as nil in the top level, and then assigning a value to it after a button’s click. The problem is the first time I open the Sheet, it somehow considers the variable as nil, however, after the second time, it’s the normal passed value, what’s the issue?

@State private var targetLast5Day: Day? = nil // Mbt4t8l4 mnl mra: `Error`

That’s the button setting value to the targetLast5Day

Button {
    targetLast5Day = day
    showLast5DaySheet.toggle()
} label: {
    CalendarItemMainPageView(passedDay: day)
}

That’s the code for the sheet

.sheet(isPresented: $showLast5DaySheet) {
                        DaySheetView(passedDay: targetLast5Day != nil ? targetLast5Day! : svm.placeholderDayObj, habitMoved: { habit, to in
                            handleHabitMove(for: habit, to: to)
                        })
                    }
