Swift Tip – Accessing a User’s Documents Directory with URL Extension

This article provides a Swift programming tip for iOS/macOS developers on how to access a user's documents directory using a URL extension. It explains the common repetitive code pattern for accessing the documents directory and offers a cleaner, DRY (Don't Repeat Yourself) solution by creating a static `documentsURL` property on the `URL` type. The extension uses `FileManager` to get the document directory URL, and the article demonstrates its usage in a Core Data stack setup for locating an SQLite database file. The tip is aimed at improving code maintainability and convenience for developers working on Apple platforms.
