How to Apply MDCSwipeToChose Framework

I am a beginner at Swift, but I would like to create an application using MDCSwipeToChoose, so I would like to refer to the following article in Qiita and create the same one for practice, but I got an error with linker command failed with exit code1 (use-v to see invocation).
I looked into it as an amateur, but I don't know how to solve it.
Could someone tell me the cause of the problem and how to solve it?

Environment:

The steps I took:

In BridgingHeader.h

#import<MDCSwipeToChoose/MDCSwipeToChoose.h>
#import<UIKit/UIKit.h>

Add (remain existing)

Among the TRAGETs in Build Settings settings, the Objective-C

Result:
When building
