Swift tutorial is in Swift 3 version?

Question

I would like to know also if there are actually a lot of diferences between Swift 3 and older versions. Thank you!

Answer 1

While learning don't bother about the version because the versions and syntax will change every time. That is the life of a developer.
Try to practice with the same version as SoloLearn do, get the code executed as expected and understand the workflow.
Have an idea, take a lot of cofee and code your dream.
Happy coding !
