How to clip a view so only part is visible
Fully updated for Xcode 11.4
SwiftUI lets you clip any view to control its shape, all by using the clipShape() modifier.
For example this creates a button using the system image “bolt.fill” (a filled lightning bolt), gives it some padding and a background color, then clips it using a circle so that we get a circular button:
Button(action: {
print("Button tapped")
}) {
Image(systemName: "bolt.fill")
.foregroundColor(.white)
.padding()
.background(Color.green)
.clipShape(Circle())
}The Circle clip shape will always make circles from views, even if their width and height are unequal – it will just crop the larger value to match the small.
As well as Circle there’s also Capsule, which crops a view to have rounded corners in a lozenge shape. For example, this creates the same button using a capsule shape:
Button(action: {
print("Button tapped")
}) {
Image(systemName: "bolt.fill")
.foregroundColor(.white)
.padding(EdgeInsets(top: 10, leading: 20, bottom: 10, trailing: 20))
.background(Color.green)
.clipShape(Capsule())
}
