Answer 2

You are using NextLevel Video Recording Library which is compiled with Swift 4.1.2 and it might have some swift version based independencies which is unavailable in your project with swift version 3.3.2 .

What to do?

Try finding the swift 3.3.2 compiled version of NextLevel Video Recording Library, or use another library.
