How do I spawn an object at a random spot on the layout view?

I'm making a game and i want an object to spawn at a random point on the screen. How do i do that??

Thank you.

Random point on the layout -

X: random(layoutWidth)

Y: random(layoutHeight)

Random point on the screen -

X: random(ViewportLeft(layer), ViewportRight(layer))

Y: random(ViewportTop(layer), ViewportBottom(layer))
