Swiftui - Remove Space Between Cells

SwiftUI - Remove space between cells

I've had good luck with listRowInsets

struct ContentView: View {
    var body: some View {
        List {
            Color.red
            .listRowInsets(.init(top: 0, leading: 0, bottom: 0, trailing: 0))
            Color.blue
            .listRowInsets(.init(top: 0, leading: 0, bottom: 0, trailing: 0))
            Color.yellow
            .listRowInsets(.init(top: 0, leading: 0, bottom: 0, trailing: 0))
        }
    }
}

SwiftUI, remove space between views in a VStack?

Since you know that your HStack with the blue rectangles is going to be a height of 150, you should constrain it to that using .frame(height: 150):

GeometryReader { geometry in
    ...
}
.padding()
.frame(height: 150) //Here

Otherwise, the GeometryReader will occupy all available vertical space.

Re: your web dev comparison, check out the Xcode view hierarchy inspector. It's not exactly the same, but it's in the same vein: https://developer.apple.com/library/archive/documentation/ToolsLanguages/Conceptual/Xcode_Overview/ExaminingtheViewHierarchy.html

SwiftUI reduce spacing of rows in a list to null

Well, actually no surprise - .separatorStyle = .none works correctly. I suppose you confused text background with cell background - they are changed by different modifiers. Please find below tested & worked code (Xcode 11.2 / iOS 13.2)

struct ContentView: View {
  @State var data : [String] = ["first","second","3rd","4th","5th","6th"]

  var body: some View {
    VStack {
      List {
        ForEach(data, id: \.self)
        { item in
          Text("\(item)")
            .background(Color.yellow) // text background
            .listRowBackground(Color.blue) // cell background
        }
      }
      .onAppear { UITableView.appearance().separatorStyle = .none }
      .onDisappear { UITableView.appearance().separatorStyle = .singleLine }
    }
  }
}

Update:

it's not possible to avoid the blue space between the yellow Texts?

Technically yes, it is possible, however for demo it is used hardcoded values and it is not difficult to fit some, while to calculate this dynamically might be challenging... anyway, here it is

it needs combination of stack for compression, content padding for resistance, and environment for limit:

  List {
    ForEach(data, id: \.self)
    { item in
        HStack {                                 // << A
          Text("\(item)")
            .padding(.vertical, 2)               // << B
        }
        .listRowBackground(Color.blue)
        .background(Color.yellow)
        .frame(height: 12)                       // << C
    }
  }
  .environment(\.defaultMinListRowHeight, 12)    // << D

How to reduce space between LazyHGrid rows?

I was thinking about this incorrectly. You can create a LazyVGrid with 7 columns and then just have a ForEach loop that creates 30 different views which will wrap around to become rows.

struct Calendar: View {

    // create 7 columns
    var cols: [GridItem] = [
        GridItem(spacing: 50),
        GridItem(spacing: 50),
        GridItem(spacing: 50),
        GridItem(spacing: 50),
        GridItem(spacing: 50),
        GridItem(spacing: 50),
        GridItem(spacing: 50)
    ]

    var body: some View {
        LazyVGrid(columns: cols, spacing: 5) {
            ForEach((1...30), id: \.self) { num in
                Text("\(num)")
            }
        }
        .frame(width: .infinity, height: 450)
        .padding()
    }
}

How to remove blank space between two text views in SwiftUI

Put it conditionally, like

if let description = men.welcomeDescription {
  Text(description)
    .font(.caption)
    .foregroundColor(.gray)
}

SwiftUI Remove List padding fand Row spacing?

For testing and showing that there is no problem with massive data, I pre loaded 10_000 row. is that enough?

your issues:

1.you should make your Item type Identifiable, then you can put out uuid from your list or ForEach.

2.you should not gave frame size to your row, they can take max space automatically.

3.you can put your button over your View, and save some more coding, like I did.

4.you should not use CGSize for offset, because you are just working on one dimension, and CGFloat is enough.

5.you should and must use LazyVStack if your data is massive as you said 400 is to many, then use LazyVStack for sure.

struct Item: Identifiable {

  let id: UUID = UUID()
  let value: String

}

                LazyVStack(spacing: 0) {

SwiftUI - i'd like to remove space between back button and .navigationbartitle

Just remove redundant NavigationView - it is needed only one in same view hierarchy, and obviously there is already some in parent view

struct RecipeIngredientsView: View {
    let myArray = ["Dennis", "Tessa", "Peter", "Anna", "Tessa", "Klaus", "Xyan", "Zuhau", "Clown", "Brot", "Bauer"]
    @State private var searchText = ""
    @State private var showCancelButton: Bool = false
    
    var body: some View {
        NavigationView         // << remove this one !!
        {

iOS 15: Remove empty space before cells in UITableView

Check if you are only seeing this issue on iOS 15. If so, this may be caused by the newly introduced UITableView.sectionHeaderTopPadding property. You will need to set this value to 0 in order to remove the spacing before section headings:

let tableView = UITableView()
tableView.sectionHeaderTopPadding = 0

// Etc.

This property is only available in iOS 15 so you will need an API check if building for earlier versions.

If you're not on iOS 15, this question has most of the answers to this issue.

How to remove the left and right Padding of a List in SwiftUI?

It looks like .listRowInsets doesn't work for rows in a List that is initialised with content.

So this doesn't work:

List(items) { item in
    ItemRow(item: item)
        .listRowInsets(EdgeInsets())
}

But this does:

List {
    ForEach(items) { item in
        ItemRow(item: item)
            .listRowInsets(EdgeInsets())
    }
}
