How to make dynamic ScrollView?

Forums > SwiftUI

Good day. Tell me how to make a dynamic ScrollView? If you add .fixedSize (horizontal: false, vertical: true), then with a large list of scrollViews it will not scroll.

struct SearchView: View {

    @State var searchText = ""

    var body: some View {
        GeometryReader { geometry in
            VStack {
                LinearGradient.customVertical.frame(height: geometry.safeAreaInsets.top + 200)
                VStack {
                    contentBlock
                }
                .padding(.top, -100)
            }
        }
        .background(Color.gray)
        .edgesIgnoringSafeArea(.all)
    }

    var contentBlock: some View {
        GeometryReader { geometry in
            VStack {
                searchBlock
                scrollBlock
            }
            .background(Color.white)
            .cornerRadius(13)
            .padding(.horizontal, 15)
        }
    }

    var scrollBlock: some View {
        ScrollView(showsIndicators: true) {
            VStack {
                ForEach(1..<10, id: \.self) { elem in
                    labelBlock(elem: "element - \(elem)")
                }
            }
        }
        .border(Color.green, width: 4)
        .fixedSize(horizontal: false, vertical: true) 
    }

    func labelBlock(elem: String) -> some View {
        VStack(alignment: .leading) {
            Text(elem)
                .font(.system(size: 16))
                .foregroundColor(Color.blue)
                .padding(.top, 18)
            Text("Text")
                .font(.system(size: 16))
                .foregroundColor(Color.gray)
                .padding(.top, 10)
            Rectangle()
                .fill(Color.black)
                .frame(height: 1)
        }
        .padding(.leading, 31)
    }

    var searchBlock: some View {
        HStack {
            ZStack {
                if searchText.isEmpty {
                    Text("Input text")
                        .font(.system(size: 14, weight: .regular))
                }
                TextField("", text: $searchText)
            }
            Spacer()
            Button(action: {
                searchText = ""
            } ) {
                Image(systemName: "xmark")
                    .foregroundColor(.blue)
                    .font(.system(size: 17, weight: .semibold))
            }
        }
        .padding(.horizontal, 15)
        .frame(height: 68)
        .overlay(RoundedRectangle(cornerRadius: 13)
                    .stroke(Color.blue))
        .padding(15)
    }

}

struct SearchView_Previews: PreviewProvider {
    static var previews: some View {
        SearchView()
    }
}

extension LinearGradient {
    static let gradientBlue = LinearGradient(gradient: Gradient(colors: [Color(UIColor.systemBlue), Color.blue]), startPoint: .top, endPoint: .bottom)
}
