A singleton is a design pattern that restricts the instantiation of a class to one object. In Swift, you can create a singleton class by using a static type property to hold a single instance of the class. Here's an example implementation:
main.swift210 chars12 lines
In this implementation, the static sharedInstance
property holds a single instance of the MySingleton
class. The private init
method ensures that no other instances of the class can be created, and the doSomething
method provides an example of a method that can be called on the singleton instance.
To use the singleton in your code, you simply call the sharedInstance
property:
main.swift71 chars3 lines
This will give you access to the shared instance of the MySingleton
class, and you can call its methods or access its properties as needed.
