What is the best text editor for opening large files? A highly specific question, and unlike asking "what's the best text editor for programmers?", this one we can answer with almost 100% objectivity. If you would rather watch a video on this subject, I've got that covered for you To do this, we'll need to do some stress testing, so

Extensions Type safe networking with URLSession, Result, and Decodable. We all know it's best practice to separate our code into individual components, each dedicated to a single task. This sounds simple enough, but rarely do we get it right the first time. Or even the fourth time. I find that within my projects, it can take me several attempts
Swift Working with very large numbers in Swift —  BigInt Numbers are fundamental to every programming language in existence. Depending on the systems architecture that you’re programming for, there are restrictions the size of the numbers it can support.
