You may also add images to customise your sliders in place of text:
a. You can upload asset images from the left hand Assets.xcassets folder and access them using
Image(<_asset name>)
b. You can do the same using systemImages that access the SF library of images
Code:
HStack{
Image(systemName: "minus")
Slider(value: $Value, in: 0...100, step:10)
.accentColor(.red)
Image(systemName: "plus")
}.padding()
Output:
