Find a window from AXUIElementCopyAttributeValue with its windowNumber to change its position

Question

I want to move a window with the Accessibility API.

With the following snippet

let options = CGWindowListOption(arrayLiteral: CGWindowListOption.excludeDesktopElements, CGWindowListOption.optionOnScreenOnly, CGWindowListOption.optionOnScreenAboveWindow)
let windowList = CGWindowListCopyWindowInfo(options, kCGNullWindowID) as NSArray? as? [[String: AnyObject]]

for entry  in windowList!
{ if let  bounds = entry[kCGWindowBounds as String] as? [String: Int],
     let owner = entry[kCGWindowOwnerName as String] as? String,
     let pid = entry[kCGWindowOwnerPID as String] as? Int32,
     let windowNumber = entry[kCGWindowNumber as String] as? Int32
  {  print("\(owner)  (\(pid)-\(windowNumber))")
     .....

the active windows are detected.

For some processes (e.g. notes), I get entries with the same pid but a different windowNumber. What I want, is to move a window with a given pid and windowNumber.

I tried with this snippet:

let appRef = AXUIElementCreateApplication(pid); 
var value: AnyObject?
let result = AXUIElementCopyAttributeValue(appRef, kAXWindowsAttribute as CFString, &value)

if let windowList = value as? [AXUIElement]
{ ...

It returns a list of the windows of a process. I want to move one of these windows with a given windowNumber (from the snippet above)

How do I find that window?
