SwiftUI Preview pauses whenever I change a file - ios

Question

I have a SwiftUI View (LandingScreenView.swift) that is using a button style implemented on another file (DefaultButtonStyle.swift). When I go to that Button Style file and change a line of code there, then return to the LandingScreenView.swift the SwiftUI preview has paused. It occurs always. This is a very fresh project with only those 2 files, I have one copy script on my build phases and I already set it to run "For install builds only". How can I make the SwiftUI works without pausing?
Xcode Version: 12.5
(I'm running it on an M1 MacBook, don't know if it makes any difference here)
import SwiftUI
struct LandingScreenView: View {
var body: some View {
VStack {
Spacer().frame(width: 0, height: 44, alignment: .center)
Text("app.title")
.font(.appTitle)
.frame(minWidth: 0,
maxWidth: .infinity,
alignment: .center)
Spacer()
VStack {
Button("landing.login.button", action: {
})
.buttonStyle(DefaultButton())
Button("landing.about.button", action: {
})
.buttonStyle(DefaultButton())
}
.frame(minWidth: 0, maxWidth: .infinity, alignment: .topLeading)
Spacer()
}.padding()
}
}
struct LandingScreenView_Previews: PreviewProvider {
static var previews: some View {
LandingScreenView()
}
}
import SwiftUI
struct DefaultButton: ButtonStyle {
func makeBody(configuration: Configuration) -> some View {
HStack {
configuration.label
.padding()
.frame(minWidth: 0,
maxWidth: .infinity,
minHeight: 44,
idealHeight: 44,
alignment: .center)
.background(Color.blue)
.foregroundColor(.white)
.cornerRadius(40)
}
}
}
EDIT:
My problem here is not that the preview has to recompile it every time. What seems a little bit weird is that I have to press the resume button every time I go out the screen and return.
