Can you help me get the GADBannerView to show in Interface Builder's Object Library? Swift 4; Xcode 10.1; Firebase SDK; Google Mobile Ads SDK

I'm not the best iOS developer or even one of the best, I just know enough (usually) to get what I need done. With that being said I'm having issues adding GADBannerView's and others to my Storyboard because the controls aren't showing up in Interface Builder's Object Library when I search for them.


I have just installed the latest Xcode (10.1), Firebase iOS SDK (v5.13.0), and the latest Google Mobile Ads SDK.


Everything in the app works as expected, the ad I programmatically included shows up. But I don't want to programmatically include every ad, I want to use Interface Builder because that's the reason it was designed; Rapid Application Development.


Fixes? Thank you in advance.
