It's easy to look at your project and think, "I could have done this better," but what does it take to really fix things? I wrote a series of articles showing exactly how to upgrade your projects for modern app infrastructure: getting great unit tests where you had none before, adopting smart coding conventions to make your work easier to read, streamlining tedious work using Fastlane, and more.

These articles all build upon the same example project from GitHub, but you can apply their principles anywhere else. If you're using my project then you should follow the articles sequentially, but if you just want to upgrade your own projects then you can read whichever articles you like – just skip to the part that interests you.

Here are direct links to the various parts:

1. How to refactor your code to add tests
2. How to add CocoaPods to your project
3. How to clean up your code formatting with SwiftLint
4. How to streamline your development with Fastlane
5. How to save and share your work with GitHub
6. How to validate code changes using CircleCI
