Avoiding singletons in Swift – John Sundell – Medium - Apple to define the “best practices” for their platforms, and any pattern that The relationships between singletons and the code that depends on them is code” that doesn't have clear separations between objects. any implementation changes, and can simply pass their shared instance as a service.
Design Patterns - Creates an instance of several derived classes; Object Pool A fine-grained instance used for efficient sharing patterns are those patterns that are most specifically concerned with communication between objects. The idea of a design pattern is an attempt to standardize what are already accepted best practices.

Singleton Design Pattern In C# - Essentially, a singleton is a class which only allows a single instance of itself to be created, and usually gives simple access to that instance. (If the same instance should be accessed for all requests with the same parameter, the factory pattern is more appropriate.)
Implementing the Singleton Pattern in C# - A singleton is a class that only allows a single instance of itself to be created, and usually gives simple access to that instance.
