Threads vs. Tasks in Swift Concurrency
Are Threads the same as Tasks in Swift Concurrency? You may wonder if you’re used to writing Swift or Objective-C using Grand Central Dispatch (GCD) and traditional APIs. A so-called threading mindset has helped us develop apps that work with asynchronous functions for years.
Modern concurrency uses Swift Concurrency and its async/await methodology. Instead of creating a closure-based method, you’ll be using a Task { ... } to start an asynchronous context. The next question you’re likely to ask yourself is whether this task will run on the main thread or a background thread. Whether that’s the case will be answered in this article, along with answering whether you should even consider the thread being used.Faster iOS app releases with automated QA If slow QA processes are slowing down your iOS releases, try QA Wolf.

What is a thread?
A thread is a system-level resource that runs a sequence of instructions. The operating system manages them, and threads have a high overhead when created or switched. Multithreading allows multiple operations to run concurrently, but managing these threads manually can be complex.
