Here’s a super-simple tip from Xcode Tips for making your Xcode console output more readable.

Automatically resolve Xcode project file conflicts
Xcode project files are complex and not meant to be human-readable, so they can be scary to merge. When there’s a conflict, it’s never fun.
The tool Kintsugi intends to automatically solve these conflicts for you “99.9% of the time.”

The name Kintsugi (ιηΆγ) is well-chosen, meaning “the art of repairing broken pottery by mending it with gold.” π€―
Another interesting note: this project relies on a framework called Xcodeproj that lets you create and modify Xcode project files automatically. That sounds likes a better alternative than a homespun shell script. π

Debug network connections right from Xcode
Debugging live network traffic in your app is always interesting. There are some great apps for tracking your network connections, such as the cross-platform classic Charles Proxy, the more modern and Mac-assed alternative Proxyman, and even an embedded framework like Pulse.
And now with Xcode 13, you can forgo the third-party apps altogether if you so choose. This comes in especially handy if your company has third-party apps locked down. π€·π»ββοΈ

Getting Started with Instruments
Has there ever been a more powerful, but under-utilised tool than Instruments?
Instruments is a tool included with Xcode that helps you analyze, profile, and debug your live iOS app. Solve memory leaks. Visualize memory. Monitor disk, network, memory, and battery usage. You can even find zombies. π§ββοΈ
It lets you do incredible things but is also overwhelming to new developers, in which case this Ray Wenderlich tutorial can come in pretty handy.

It’s Time for Snapshot Testing
I love the idea of snapshot testing. It’s a simple way to automatically test an app’s UI.
It works like this:
- Set the app up in a certain state and take a screenshot. Save the screenshot. πΈ
- Next time when you run the same test, you compare screenshots. π· πΈ
- If something changed unexpectedly, then you know there’s trouble. π₯
Here’s a nice series about how to do it for iOS/ Xcode.

And GitHub: swift-snapshot-testing
The coolest thing is that you actually upload your screenshots in any new pull requests, so you can literally see what the change is all about (“The perfect pull request”). π€―
