I am trying to use SettingsManager as stated in [Pair and Manage Card Readers](https://developer.squareup.com/docs/mobile-payments-sdk/ios/pair-manage-readers) to pair square reader:

`SettingsManager.presentSettings(self)`

For some reasons it is throwing following compilation error:

`Argument type 'ViewController' does not conform to expected type 'SettingsManager'`

Am I missing anything over here?

The team is going to update the documentation but if you use `MobilePaymentsSDK.shared.settingsManager.presentSettings(viewController: self) { _ in }` instead it will work. 🙂
