How to apply shadow to interior views in SwiftUI?

You can use clipped() here to fix this

VStack() {
    Text("Text")
        .background(Color.red)
        .padding()
        .padding()

    Text("Text")
        .background(Color.purple)
        .padding()
}
.padding()
.background(Color.white)

.clipped()
.shadow(color: Color.red, radius: 10, x: 0, y: 0)

Output:
