I faced the same problem. But I was building the UI through code.

import MaterialComponents.MaterialButtons
import MaterialComponents.MaterialButtons_Theming

let button = MDCButton()
button.applyTextTheme(withScheme: MDCContainerScheme())

The following helped me. I just called the option Product -> Clean Build Folder. After that, the abnormal termination of the program disappeared.

From the error, you can see that UIButton does not have a method called applyOutlinedThemeWithScheme, which could mean that in your storyboard or XIB, you are using a UIButton instead of a MDCButton.

In your storyboard or XIB, go to Identity Inspector, make sure Class is set to MDCButton.
