How to Put View on Top of All Other Views in Swiftui

How to put View on top of all other views in SwiftUI

Try to put everything in ZStack and use zIndex for DropdownButton to put it atop, like

ZStack {
   // ... other content here
   DropdownButton(displayText: "This month", 
                  selectedKey: .constant("Test"), 
                  options: options).zIndex(10)

   // ... other content here

Presenting - Show a view on top in SwiftUI (I don't want to navigate)

I solved it by placing

if(incomeFill_show) {
                    BudgetAlert(amount: .constant("400"))
                }

at the bottom of the List: like this

var body: some View {
        VStack(alignment: .leading, spacing: 8) {
            headerView.padding().background(Color.white)
            ZStack(alignment: .center) {

                List() {
                    VStack {
                        Section(header: self.getHeaderView()) {
                            ForEach(categoriesData) { category in
                                HStack(alignment: .bottom) {
                                    CategoryProgressView(category: category, value: .constant(.random(in: 0.1 ... 1)))
                                    self.valuesText(category: category)
                                }

                            }
                            .colorMultiply(Colors.SharedColors.backgroundColor)
                        }
                    }
                }
                .colorMultiply(Colors.SharedColors.backgroundColor)
                .onAppear {UITableView.appearance().separatorStyle = .none}
                .onDisappear { UITableView.appearance().separatorStyle = .singleLine }

                if(incomeFill_show) {
                    BudgetAlert(amount: .constant("400"))
                }
            }

        }.background(Colors.SharedColors.backgroundColor)
    }
}

for blurred background you can see this code here:

var body: some View {
        VStack {
            Spacer()
            ZStack(alignment: .center) {
                RoundedRectangle(cornerRadius: 10).foregroundColor(Color.white)
                VStack {
                    Text("Add your Income").font(Fonts.mediumFont)
                    HStack(alignment: .center, spacing: 0) {

                        CustomTextField(placeHolderLabel: "Amount", val: $amount, keyboardType: UIKeyboardType.decimalPad).padding()

                         HStack {
                             Button("\(currency.rawValue)"){
                                 self.show_currencyActionsheet = true
                             }
                                 .font(Fonts.callout)
                                 .foregroundColor(Colors.textFieldFloatingLabel)
                             .actionSheet(isPresented: self.$show_currencyActionsheet) {self.actionSheetCurrency}
                             Image(systemName: "chevron.down")
                              .imageScale(.small)
                        }.padding()
                    }.padding([.leading,.trailing])

                    Button(action: {
                        self.callBack()
                    }) {

                        Text("                Add Income                ").font(Fonts.callout).foregroundColor(Color.white)
                    }
                    .padding()
                    .background(Colors.darkGreen)
                    .clipShape(Capsule())
                }
            }.frame(minHeight: 150, idealHeight: 182, maxHeight: 200)
            .padding()
            Spacer()

        }.background(VisualEffectView(effect: UIBlurEffect(style: .dark))
        .edgesIgnoringSafeArea(.all))
    }

struct VisualEffectView: UIViewRepresentable {
    var effect: UIVisualEffect?
    func makeUIView(context: UIViewRepresentableContext<Self>) -> UIVisualEffectView { UIVisualEffectView() }
    func updateUIView(_ uiView: UIVisualEffectView, context: UIViewRepresentableContext<Self>) { uiView.effect = effect }
}

but I prefer to go with faded background

Place view on top of others SwiftUI

SwiftUI uses ZStack{} for layered views.

Here’s a good primer: https://www.hackingwithswift.com/quick-start/swiftui/how-to-layer-views-on-top-of-each-other-using-zstack

I’m sorry it’s nearly 1am here and I don’t have time now for a more thorough answer, but I see you’re active 3min ago, and that should point you in the right direction.

How can I make a view align it's center to the top of another view in SwiftUI?

A possible approach is to use alignmentGuide modifier, which allows to fit specific internal alignment line to parent container. So by default containers have center alignment, so using top anchor instead for one of views result in align other's center to top.

Tested with Xcode 13.2 / iOS 15.2

struct DemoView: View {
    var body: some View {
        ZStack {
            Rectangle().fill(.red)
                .frame(width: 300, height: 200)
                .alignmentGuide(VerticalAlignment.center) {   // << here !!
                    $0[VerticalAlignment.top]
                }
            Rectangle().fill(.green)
                .frame(width: 100, height: 80)
        }
        .border(Color.black)
    }
}
