Mon, 02 Oct 2023 09:17:48 +0200

Introduction

SwiftUI provides multiple styles for list, but it might not always be obvious what difference there are between them.

This is a comparison grid of all iOS list styles, described in [STYLES]. The code for the list is written out at the bottom of the page.

Comparisons

.plain

.inset

.grouped

.insetGrouped

.sidebar

Code

List {
 Section {
 Text("Apple")
 Text("Banana")
 } header: {
 Text("Favorites")
 } footer: {
 Text("The fruits which are most tasty")
 }

 Section {
 Text("Orange")
 }
}

SwiftUI iOS List default selection with NavigationSplitView

Thu, 17 Aug 2023 02:48:52 +0200

Introduction

Looking through Apple’s documentation, I found no clear example of how to set a default selected option for a List in a NavigationSplitView.

This post shows how to the the default selected option in a list, and how to best interact with a split view.

Example

Clear example of how to set a default selected option for a sidebar List in a NavigationSplitView.

@State private var selectedId: String? = "banana"

NavigationSplitView {

 List(selection: $selectedId) {

 NavigationLink(value: "apple") {
 Text("Apple")
 }

 NavigationLink(value: "banana") {
 Text("Banana")
 }

 }
} detail: {
 Text("\(selectedId ?? "Nothing selected")")
}

We use "NavigationLink" with a "value:" parameter instead of navigating to a new view, and keep track of the selection in "selectedId"; the “selected” value must be optional for iOS [1].
