How to make a .onAppear

Forums > SwiftUI

Hello together,

i am working on a Set Game and I want the cards to swing on the view via the .transition(.asymmetric(insertion: .offset(x: 100.0, y: 100.0), removal: .offset(x: 100.0, y: 100.0))) command.

Actually, they leave the screen by doing exactly the offset, but they just appear at the start on the program.

Can someone tell me what I am doing wrong?

    @ViewBuilder
    private func body (for size: CGSize) -> some View{
        let paddingAllSidesInCards:CGFloat = 8
        if card.isFaceUp || !card.isMatched
        {
            GeometryReader { geo in
                VStack(alignment: .center) {
                    Group
                    {

                            ForEach( 0..<card.numberofsymbols)
                            { numberofcards in

                                let cardshape = cardViewModelShape.getShape(Card: card, size: size, numberOfCards: card.numberofsymbols)
                                    cardshape
                                    .aspectRatio(1,contentMode: .fit)
                                    .frame(minWidth: 20, idealWidth: 100, maxWidth: .infinity, minHeight: 20, idealHeight: 100, maxHeight: .infinity, alignment: .center)
                                    .scaleEffect(card.isSelected ? 1.2 : 1)
                                    .animation(.spring(response: (card.isSelected ? 1:0), dampingFraction: 0.1, blendDuration: .infinity))
                            }.padding(paddingAllSidesInCards)
                        //Implicit animation - with linear execution
                    }
                }
                .cardify(isFaceUp: card.isFaceUp)
//                .animation(Animation.easeIn(duration: 2))

            }
            .transition(.asymmetric(insertion: .offset(x: 100.0, y: 100.0), removal: .offset(x: 100.0, y: 100.0)))

        }
    }
}
