im having trouble setting up 47 facility Bool filters to a json list like the Landmark tutorial json List

its only this first 10 filters that work and the rest don't work when I try them what im I doing wrong..??

var filteredHavneplaner: [Havneplan] {

        userData.havneplaner.filter { havneplan in

            (!filters.showhjertestarterOnly || havneplan.hjertestarter) && (!filters.showpaabroerneOnly || havneplan.paabroerne) && (!filters.showautocamperOnly || havneplan.autocamper) && (!filters.showbeddingOnly || havneplan.bedding) && (!filters.showbenzinOnly || havneplan.benzin) && (!filters.showblaaflagstrandOnly || havneplan.blaaflagstrand) && (!filters.showBaadtilbehorOnly || havneplan.Baadtilbehor) && (!filters.showbaadevaerftOnly || havneplan.baadevaerft) && (!filters.showcykeludlejningOnly || havneplan.cykeludlejning) && (!filters.showdieselOnly || havneplan.diesel) && (!filters.showdykkerklubOnly || havneplan.dykkerklub) && (!filters.showdykkerassistanceOnly || havneplan.dykkerassistance) && (!filters.showelektricitetOnly || havneplan.elektricitet) && (!filters.showelvaerkstedOnly || havneplan.elvaerksted) && (!filters.showfamiliebaderumOnly || havneplan.familiebaderum) && (!filters.showflaskegasOnly || havneplan.flaskegas) && (!filters.showgrillpladsOnly || havneplan.grillplads) && (!filters.showhavnebadbadebroOnly || havneplan.havnebadbadebro) && (!filters.showkrabbebaneOnly || havneplan.krabbebane) && (!filters.showkøbmandsupermarkedOnly || havneplan.købmandsupermarked) && (!filters.showlegepladsOnly || havneplan.legeplads) && (!filters.showmotorassistanceOnly || havneplan.dykkerassistance) && (!filters.showmotorbådsklubOnly || havneplan.motorassistance) && (!filters.shownaturformidlingOnly || havneplan.naturformidling) && (!filters.showsejlmagerOnly || havneplan.sejlmager) && (!filters.showslæbestedOnly || havneplan.slæbested) && (!filters.showsejlklubOnly || havneplan.sejlklub) && (!filters.showshelterOnly || havneplan.shelter) && (!filters.showstrandOnly || havneplan.strand) && (!filters.showsupklubOnly || havneplan.supklub) && (!filters.showtoiletbadOnly || havneplan.toiletbad) && (!filters.showtomningaftankOnly || havneplan.tomningaftank) && (!filters.showtorretumblerOnly || havneplan.torretumbler) && (!filters.showudlejningshytterOnly || havneplan.udlejningshytter) && (!filters.showvandlegepladsOnly || havneplan.vandlegeplads) && (!filters.showvandpolobaneOnly || havneplan.vandpolobane) && (!filters.showvinterbadereOnly || havneplan.vinterbadere) && (!filters.showvaskemaskineOnly || havneplan.vaskemaskine) && (!filters.showoffentligtransportOnly || havneplan.offentligtransport) && (!filters.showwifiOnly || havneplan.wifi) && (!filters.showvaerftOnly || havneplan.vaerft) && (!filters.showrestaurantOnly || havneplan.restaurant) && (!filters.showsejlerstueOnly || havneplan.sejlerstue) && (!filters.showbadOnly || havneplan.bad) && (!filters.showfrihavnOnly || havneplan.frihavn) && (!filters.showsikkerhavnOnly || havneplan.sikkerhavn) && (!filters.showonlinehavnepengeOnly || havneplan.onlinehavnepenge) && (!showFavoritesOnly || havneplan.isFavorite) && (filters.minlaengde < havneplan.laengde) && (filters.minbredde < havneplan.bredde) && (filters.mindybgang < havneplan.dybgang) && (filter == .all || filter.rawValue == havneplan.category.rawValue) && (filtertwo == .all || filtertwo.rawValue == havneplan.typehavn.rawValue)

How did you get on with this question on Stack Overflow?

I don't know how to solve your issue, but perhaps this clue will help...

In SwiftUI, a ViewBuilder is limited to a maximum of 10 Views.
It looks like there may be a similar limit to filters?

I found your code a bit confusing (json doesn't seem to have any relevance), but I suspect there may be a more elegant solution.

Would you like to post a bit more about what you are trying to achieve, and how (and why)?

Have you considered rewriting it as a method that tests each Bool individually, and returns the overall Bool result?
Perhaps something like...

func include() -> Bool {
    if !filters.showhjertestarterOnly || havneplan.hjertestarter {
        return true
    }
    if !filters.showpaabroerneOnly || havneplan.paabroerne {
        return true
    }
    /// And so on, through your 47 Bools...
    return false
}

10 is a frequent limit in SwiftUI.

Can't you split the filtering by groups of 10 filters ?
