Use data from CoreData in label

world! I work in SwiftUI, I want to use data from CoreData in label.

Use likedDBE.isLiked instead of cellViewModel.isLiked. How can this be implemented?

Button(action: {
    let likedDBE = LikedDBE(context: self.managedObjectContext)
    likedDBE.name = cellViewModel.card.name
    likedDBE.price = cellViewModel.card.price
    likedDBE.isLiked = cellViewModel.isLiked
    do{
        try self.managedObjectContext.save()
    }catch {
        print(error)
    }
}, label: {
    Image(systemName: cellViewModel.isLiked ? "heart.fill" : "heart") //In this place
        .frame(width: 22, height: 22)
        .foregroundColor(cellViewModel.isLiked ? .red : .black) //And in this place
    
})

Thank you all in advance!

you cannot use likedDBE.isLiked in the Button label part, because it is only available in the Button action part. So
move the likedDBE outside the Button action, for example:

// somewhere appropriate in your code and accessible to the button
var likedDBE = LikedDBE(context: self.managedObjectContext)
likedDBE.name = cellViewModel.card.name
likedDBE.price = cellViewModel.card.price
likedDBE.isLiked = cellViewModel.isLiked

// just keep the saving in the button action.
Button(action: {
    do{
        try self.managedObjectContext.save() // <--- here keep this
    }catch {
        print(error)
    }
}, label: {
    Image(systemName: likedDBE.isLiked ? "heart.fill" : "heart")   // <--- here can use likedDBE
        .frame(width: 22, height: 22)
        .foregroundColor(likedDBE.isLiked ? .red : .black)   // <--- here can use likedDBE
})
