Solved it, replace: textPaneVersion.stringValue = Bundle.main.object(forInfoDictionaryKey: kCFBundleVersionKey as String) as! String With: textPaneVersion.stringValue = self.bundle.object(forInfoDictionaryKey: kCFBundleVersionKey as String) as! String

Hi, sorry for my late reply, I made a repo on github, with the expected result as well as actual result. textPaneVersion.stringValue = Bundle.main.infoDictionary!["CFBundleVersion"] as! String Gave the result of 14.0, that's not anywhere in my project versions, my project version is 1.0. So its using system preferences version instead of my pane version.
