Is there an answer key for the experiment tests on the Swift Guided Tour playground?

Good.
I do not think so, I am also using that App in recent months because I have been learning Swift's language for 2 months. Let's see the meaning of that App is that through your code, you move the byte that we have on the right to be able to complete its objectives. In which ways you complete your code is indifferent, but it is more to put into practice the knowledge that you are acquiring with the study and put it into practice in the App.
