URL Scheme "Open Settings" ios

As of iOS 8, it's possible to launch the Settings app that directly opens your Privacy app section in this way:

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];

In Swift:

if let settingsURL = NSURL(string: UIApplicationOpenSettingsURLString) {
    UIApplication.sharedApplication().openURL(settingsURL)
}

In Swift 3.0:

if let settingsURL = URL(string: UIApplicationOpenSettingsURLString + Bundle.main.bundleIdentifier!) {
    UIApplication.shared.openURL(settingsURL as URL)
}
