Moving windows programmatically on MacOS in Swift - swift

Question

I'm trying to move a window programmatically on my desktop. For this I've tried:
let options = CGWindowListOption(arrayLiteral: .excludeDesktopElements, .optionOnScreenOnly)
let windowsListInfo = CGWindowListCopyWindowInfo(options, CGWindowID(0))
let windowsList = windowsListInfo as NSArray? as? [[String: AnyObject]]
let visibleWindows = windowsList?.filter{ $0["kCGWindowLayer"] as! Int == 0 }
for window in visibleWindows! {
let windowTitle = window["kCGWindowOwnerName"] as! String
let windowNumber = window["kCGWindowNumber"] as! Int32
if windowNumber == 124 { // Safari
let nsWindow = NSApp.window(withWindowNumber: Int(windowNumber))
nsWindow?.cascadeTopLeft(from: NSPoint(x: 100.0, y: 100.0))
nsWindow?.setFrameTopLeftPoint(NSPoint(x: 100.0, y: 100.0))
}
}
}
but when I'm trying to get NSWindow by using windowNumber:
NSApp.window(withWindowNumber: Int(windowNumber))
I get nil.
So my question is, how can I move any window programmatically by knowing its windowNumber?
I've even tried to bring that window to front and
let pid = window["kCGWindowOwnerPID"] as? Int32 {
let app = NSRunningApplication(processIdentifier: pid)
app?.activate(options: .activateIgnoringOtherApps)
doing this but nothing helped me.
Could someone help me to find out the way how I can move the Safari window(for example) programmatically?

This should get the trick done:
let owner = entry[kCGWindowOwnerName as String] as! String
var bounds = entry[kCGWindowBounds as String] as? [String: Int]
let pid = entry[kCGWindowOwnerPID as String] as? Int32
if owner == "Safari"
{
let appRef = AXUIElementCreateApplication(pid!);
var value: AnyObject?
let result = AXUIElementCopyAttributeValue(appRef, kAXWindowsAttribute as CFString, &value)
if let windowList = value as? [AXUIElement] {
print ("windowList #\(windowList)")
if let window = windowList.first
{
var position : CFTypeRef
var size : CFTypeRef
var newPoint = CGPoint(x: 0, y: 0)
var newSize = CGSize(width: 300, height: 800)
position = AXValueCreate(AXValueType(rawValue: kAXValueCGPointType)!,&newPoint)!;
AXUIElementSetAttributeValue(windowList.first!, kAXPositionAttribute as CFString, position);
size = AXValueCreate(AXValueType(rawValue: kAXValueCGSizeType)!,&newSize)!;
AXUIElementSetAttributeValue(windowList.first!, kAXSizeAttribute as CFString, size);
}
}
}
By the way, I found this code in another discussion which I can't find at the moment, sorry about that
Oh and you need this code to request the accessibility access:
let options: NSDictionary = [kAXTrustedCheckOptionPrompt.takeUnretainedValue() as String : true]
let accessEnabled = AXIsProcessTrustedWithOptions(options)
if !accessEnabled {
print("Access Not Enabled")
}
Hope this helps, even if it's been a year and five days since you posted this question :)
