How to open multiple photos in Preview App with NSWorkspace

let photos = [NSURL(string: "/photo1.png")!, NSURL(string: "/photo2.png")!]

NSWorkspace.sharedWorkspace().openURLs(photos, withAppBundleIdentifier: "com.apple.Preview", options: NSWorkspaceLaunchOptions.Default, additionalEventParamDescriptor: nil, launchIdentifiers: nil)

I tried the code above. It returns true and opens the preview app but not with photos. Single item in array didn't work either. What am I doing wrong?

I know this was asked a long time ago, but I recently needed to do the same thing and got it working by using full paths to the image files.

// get application url from bundle ID
guard let previewUrl = NSWorkspace.shared.urlForApplication(withBundleIdentifier: "com.apple.Preview")
else { return }

// paths to image files
let urls = [
    URL(fileURLWithPath: "/Users/myuser/path/to/image1.jpg"),
    URL(fileURLWithPath: "/Users/myuser/path/to/image2.jpg")
]

// launch configuration
let config = NSWorkspace.OpenConfiguration()
config.addsToRecentItems = false
config.createsNewApplicationInstance = true
config.allowsRunningApplicationSubstitution = false
config.activates = true

// launch Preview.app
NSWorkspace.shared.open(urls, withApplicationAt: previewUrl, configuration: config) { app, error in
    if let error = error {
        print("unable to launch Preview.app: \(error.localizedDescription)")
        return
    }

    if let app = app {
        print("launched Preview.app with pid \(app.processIdentifier)")
    }
}
