Install pod for Material Design swift 4

I am doing an application with Xcode 9.4.1 with swift 4. I would like to include the MaterialDesign components, however, it is not working for me.

This is my Podfile

source 'https://github.com/CocoaPods/Specs.git'
target 'ProbandoMDC' do
    pod 'MaterialComponents'
    pod 'MaterialComponents/TextFields'
end

When I try to add the import inside my ViewController I receive the message: No such module 'MaterialComponents.MaterialTextFields'

Am I omitting something that I must do in Xcode about the project? I already tried to add the components in the Linked Frameworks and Libraries section
