Question

I am trying to open the user's iCloud settings through my iOS App. Currently, I have this:

@IBAction func openSettings(_ sender: AnyObject) {
    guard let settingsUrl = URL(string: UIApplicationOpenSettingsURLString) else {
        return
    }

    if UIApplication.shared.canOpenURL(settingsUrl) {
        UIApplication.shared.openURL(settingsUrl)
    }

}

However, this opens the app's . How can I open the user's iCloud settings? Thanks!

Try this:

let settingsCloudKitURL = URL(string: "App-Prefs:root=CASTLE")
if let url = settingsCloudKitURL, UIApplication.shared.canOpenURL(url) {
    if #available(iOS 10, *) {
        UIApplication.shared.open(url, options: [:], completionHandler: nil)
    } else {
        UIApplication.shared.openURL(url)
    }
}
