There are so many ways Kaleidoscope comes in handy as a developer. Kaleidoscope is a developer tool that can compare files to see what changed between them. You can compare your code, a design image vs. the final outcome and even a PDF to see changes in a contract (for example). Kaleidoscope provides a much better visualization when reviewing your own code or a teammates pull request and can help you untangle merge conflicts with their three way merge tool. Kaleidoscope even integrates with the Xcode debugger to help you compare large printouts to the console.
