static func GetCardsToLearnPredicate() -> Predicate<Card> {     
        let todayMinus3Days: Date = Date.now.addDay(day: -3)
        let todayMinus7Days: Date = Date.now.addDay(day: -7)
        let todayMinus14Days: Date = Date.now.addDay(day: -14)
        let todayMinus30Days: Date = Date.now.addDay(day: -30)
        
        return #Predicate<Card> {card in
            card.box == 1 || (card.box == 2 && card.lastStatusChange >= todayMinus3Days) || (card.box == 3 && card.lastStatusChange >= todayMinus7Days) || (card.box == 4 && card.lastStatusChange >= todayMinus14Days) || (card.box == 5 && card.lastStatusChange >= todayMinus30Days)
        }
    }

I get the error: “The compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions”

That is where the predicate is used:

@Query(filter: Card.GetCardsToLearnPredicate())
    var fetchedCards: [Card]

If I try to breaking it up into sub-expressions with some let’s then the compiler tells me, that a Predicate is only allowed to have one line of expression.

I already excluded the date manipulation because the compiler don’t get it inside of the predicate.

I don’t know what to do, also google doesn’t helped me out. It can’t be the truth that I can’t query data with only 1 or 2 expressions.

I’m new in the iOS swift field, was working c# for years and in the OR-Mappers I used there, that was no problem at all.
