![]() However, the clock speed for the A14 is still around 3.1 GHz. The M1 processor, used in Macs and the iPad, has eight CPU cores. Apple’s newer processors, like the A14, found in the iPhone 12, have six CPU cores. However, a noteworthy improvement to processors is the presence of more CPU cores on each chip. Despite an increase in the number of transistors in newer processors, there has not been a significant improvement in clock speed. Let’s get started! Concurrency and CPU coresĭue to changes made to processors throughout the last decade, concurrency has become a more relevant topic in computer programming. Then, we’ll learn to use the async and await keywords to enforce concurrency. In this tutorial, we’ll discuss what concurrency is and why it is useful. Nowadays, we can enforce primitives for concurrency using the async and await keywords. In the past, you could imitate primitives in Swift using libraries like Grand Central Dispatch (GCD) and libdispatch. Despite improvements made to Swift, a key feature that is still missing is primitives for concurrency and parallelism. Since then, Apple has open-sourced the language, and as a result, it continues to evolve. Chris Lattner, who designed Swift at Apple, had the goal of making a language that could be used both for teaching programming and building software for operating systems. When Swift was first introduced by Apple in 2014, it aimed to meet all of the demands that software engineers had for modern programming languages.
