How can I change the value of a SwiftUI Slider
by tapping on it?
Here's a minimal implementation I created using a GeometryReader that rounds to the closest value:
struct TappableSlider: View {
var value: Binding<Float>
var range: ClosedRange<Float>
var step: Float
var body: some View {
GeometryReader { geometry in
Slider(value: self.value, in: self.range, step: self.step)
.gesture(DragGesture(minimumDistance: 0).onEnded { value in
let percent = min(max(0, Float(value.location.x / geometry.size.width * 1)), 1)
let newValue = self.range.lowerBound + round(percent * (self.range.upperBound - self.range.lowerBound))
self.value.wrappedValue = newValue
})
}
}
}
which can be used just like a normal slider, e.g.
TappableSlider(value: $sliderValue, in: 1...7, step: 1.0)
