Compare Static and Class Keyword in Swift

First of all, we will look into below example:

How is different? Yup, nothing! So why do both of them exist?

In the following, we will look at their similarities and differences and we will know why they both exist.

Conclusion: we can conclude the similarities and differences as in the following table:
