Swift Threads: The Guide
Nothing To Do With Clothes

Prerequisites
- Be able to produce a “Hello, World!” SwiftUI project
Keywords and Terminology:
RunLoop: an object that manages events and tasks within a thread, including the main thread, and ensures the thread remains active and responsive.
Thread: Tasks can have their own threads of execution to stop long-running tasks block the execution of the rest of the application
Threads
A thread can be thought of as a sequence of instructions that can be executed (independently of other threads). By executing tasks on multiple threads an application can perform multiple tasks simultaneously which can ultimately increase performance and responsiveness.
