Hi! While programming in Swift I have accumulated many code snippets. Some of them are mine and some of them come from the internet. Here I’m sharing 5 tiny quality-of-life snippets. Hopefully you will find them useful.

Hi! In this post I will show you how to write a “screenshot taker” for a Cocoa app. It will allow the user to select a part of the screen, just like the builtin screenshot taking tool on macOS. It uses CGWindowListCreateImage (macOS 10.5 - 14.0), so it should work in old codebases although it’s important to note that it’s deprecated in macOS 14.0. In such case you should use ScreenCaptureKit and it’s functions like captureScreenshot. It should work well for most cases. Well, let’s start!
