In our mac catalyst app we access AppKit api's by using MacOS bundle(plugin).
when using CGDisplayCreateImage(_: CGDirectDisplayID, rect: CGRect) method the plugin crashes.
Implementation:
@objc
func windowMoved(_ notification: NSNotification) {
guard let win = self.window else {
return
}
let displayId = CGMainDisplayID()
let winRect = win.contentView?.convert(qrRect, from: self)
var rect = win.convertToScreen(winRect ?? self.bounds)
if let screenFrame = NSScreen.main?.visibleFrame {
rect.origin.y = screenFrame.height - rect.maxY
rect.origin.y += screenFrame.minY + win.titlebarHeight
}
guard let image = CGDisplayCreateImage(
displayId,
rect: rect) else {
return
}
guard let qrString = image.detectQRCode().first else { return }
// ...
}
Crash report in printed in console:
