6 min readTo access nested object properties in Swift, you can use dot notation chaining. For example, if you have a nested object structure like person.address.city, you can access the city property by chaining the dot operator like this: person.address.city. This allows you to access properties deep in the nested object structure without having to write separate statements for each level of nesting. Additionally, you can use optional chaining to safely unwrap optional values at each level of nesting.

7 min readIn Haskell, memory management is handled automatically by the garbage collector. When you no longer need a specific data structure, you can simply stop referencing it in your code, and the garbage collector will eventually reclaim the memory used by the data structure. This process is known as garbage collection, and it ensures that memory is used efficiently and effectively in Haskell programs.

7 min readIn Swift, the @escaping keyword is used when passing a completion closure as a parameter to a function. By default, closures are non-escaping, which means they are called within the scope of the function where they are defined. However, if a closure is passed as a parameter to a function and stored for later use outside of that function's scope, it must be marked as @escaping.To use @escaping, simply add it before the closure parameter type in the function signature.

The boot() method is called after all other service providers have been registered, giving the service provider a chance to interact with other parts of the application.
