When to make a class as Singleton in Swift?

Question

I have made a class that will contain all the utility methods. So, instead of making it as a singleton, I have marked the methods as static and accessing those methods by the ClassName.methodName without the need for instantiation. Is this approach OK?

Answer 1

Just consider that a singleton is used in order to ensure that only one instance exists for a given class, and that there’s a global access point to that instance.

I believe that having all utility functions marked as static within a class is a good approach since, as you have stated, you will need to use ClassName.methodName in order to use them.

In addition, based on what you want to achieve and the information provided by this link, I would reassert that having a class with static methods is the best alternative.
