Swift macos アプリでファイルパーミッションエラーになる(App Sandboxの制御)

SwiftでDownloadフォルダのファイル名を変えようとすると、パーミッションエラー

try FileManager.default.moveItem(atPath: oldPath, toPath: newPath)

以下赤字のようなエラー

RENAME:/Users/hirotoyagi/Downloads/apache_tomcat/tomcat4/with_iis.html -> /Users/hirotoyagi/Downloads/apache_tomcat/tomcat4/with_iis.html.origin
