Can computed properties have multiple properties on the setter

I'm very new to swift and have been having a hard time figuring out computed properties. Is there a way to pass in multiple properties to a setter or are you limited to just one? I'm attempting the following code but receive this error Expected '{' to start setter definition and Expected '}' after setter parameter name

I'm confused as to the whole type defining in swift also and have tried passing a dictionary into the setter but that then causes issues with my return type.

The code I currently have:

   struct Shape {
        var height: Int = 0
        var width: Int = 0

        var area: Int {
            set (width, height) {
                self.width = width
                self.height = height
            }

            get {
                return self.width * self.height
            }
        }
    }
