ChatGPT found a way to deal with this using deprecated symbols: try NSWorkspace.shared.open([path.url], withAppBundleIdentifier: "com.apple.dt.Xcode", options: .default, additionalEventParamDescriptor: nil, launchIdentifiers: nil) I suppose there is something wrong with the latest APIs.

Finally found the answer, you can use the legacy API, which works flawlessly. LSOpenCFURLRef(url as CFURL, nil)
