Ever since upgrading to Xcode 9 (and thus Swift 4), my Mapbox framework is causing new errors to show in the console, despite working perfectly in simulators and on devices. I don't know if these errors are just now being displayed in the console since the upgrade or if there is a conflict with the upgrade. What do these errors mean and how can they be resolved?
