SwiftUI requires that we add labels to its controls, and it's common to want to hide those labels so you can get a more precise UI layout. However, there's a bad way of hiding labels and a good way, and it's already common to see folks choosing the bad choice despite it actively hurting users.
First, let's look at the * * way to hide labels. As an example, here's a Picker that lets users select a number:
struct ContentView: View {
@State private var selectedNumber = 0
var body: some View {
Picker("Select a number", selection: $selectedNumber) {
ForEach(0..<10) {
Text("\($0)")
}
}
}
}
On some platforms, that will show “Select a number” alongside the picker. This can look poor, because the label is sometimes crammed into a small space – a better idea would be to have a VStack with a custom text label, then hide the label in the Picker.
To hide the label for a Picker – or indeed for a DatePicker, a Stepper, a Toggle, or any other view that requires a label – you should add the labelsHidden() modifier to the view, like this:
struct ContentView: View {
@State private var selectedNumber = 0
var body: some View {
Picker("Select a number", selection: $selectedNumber) {
ForEach(0..<10) {
Text("\($0)")
}
}
.labelsHidden()
}
}
That still creates the label, but now it doesn't get shown no matter what platform is used. As a result, you can put the Picker inside a VStack and add a label of your own choosing.
Tips
If you want all your labels hidden you can apply the labelsHidden() modifier to a VStack or whatever you're using as your outermost container.
In case you were curious, the wrong way to hide labels is using EmptyView, like this:
struct ContentView: View {
@State private var selectedNumber = 0
var body: some View {
Picker(selection: $selectedNumber, label: EmptyView()) {
ForEach(0..<10) {
Text("\($0)")
}
}
}
}
Yes, the end result might look the same, but there's an important reason why using labelsHidden() is much better: the hidden label is still accessible by the screen reader, so even though the text isn't visible it's still there to help VoiceOver understand how your UI is structured.
