The state of the art is:
public private(set) var foo = 0
If I'm reading and understanding this correctly, you propose a generally postfix solution like this:
public var foo = 0 {  // marks default getter and setter public however...
  private set         // marks default setter private
Unless there's a specific getter or setter implementation, I'm not fond of the
postfix declarations. In my opinion `private set` is modifying `public`, not `var foo = 0`

I recognize that in a type rather than a global variable, the modification
override could not be adjacent. Another comparison. Current art:
public struct bar {
    private(set) var gar = 0
vs (what I think is) your suggestion:
public struct bar {
    var gar = 0 {
        private set
And again, moving the access control modification to the end just doesn't look 
right to me or seem to enhance readability. :(
