Once every few months i perform the much needed relieving task of freeing disk space out of my 256GB Mac. I often use CleanMyMac is an ideal software for periodically cleaning out your disk space with some added performance and security optimizations. However when you wan't to clean out your dev environment it takes a few manual commands to get the job done since disk cleaner software won't know what to clear. You'd be surprised how much space you recover after clearing out unused dev resources. This article describes how to free storage space for Mobile Developement in a Mac laptop.
Android
1. Clean up Gradle
Your Gradle Home directory contains wrapper ,caches and daemons files. The more projects with diffferent gradle versions the more subdirectories within those three folders. You can delete all three directories. This saved me a cool ~12GB of space.
You could run the command as below to achieve the desired result.
cd ~/.gradle rm -rf caches daemon wrapper
2. Android SDK Cleaning
Android System images are only used by emulators. If you use a real Android device during development for debugging, you no longer need them, so you can remove them all. This could easily save you 5GB doing this.
iOS
Its easy to run out of space while doing iOS Development since Xcode loves to cache things everywhere around your Mac. It gets even complicated once Xcode has an update(~11GB) but realistically its around ~40GB free space required to download and install the update. Sadly i've had to delete Xcode and install it again to make it work again.
1. Remove Old Simulators
As with Android the major culprit will be old simulators that take alot of space. The simulator files are by default located in
~/Library/Developer/Xcode/iOS/Device Support folder. You can delete old simulators using the following command.
xcrun simctl delete unavailable
2. Remove Cocoapod Caches
If you use Cocoapods in your projects you can clear them using this command. Don't worry you can rebuild them later again.
rm -rf "${HOME}/Library/Caches/CocoaPods"
3. Clean up Archives,Logs and DerivedData folders
Folders like DerivedData can take up a significant amount of space too. DerivedData is generated during each build process. This contains intermediate build results,indexes that speed up time on each build. You can use the command below to clear all that data.
rm -rf ~/Library/Developer/Xcode/Archives rm -rf ~/Library/Developer/Xcode/DerivedData rm -rf ~~/Library/Developer/Xcode/iOS Device Logs/
DevCleaner for Mac
If you're not to keen in heading to this article again to clean up your iOS Development workspace, you can download this DevCleaner by One Minute Games that handles it superbly.
Conclusion
Don't forget to empty your trash to check out how much space you have available. I was able to clear around ~15GB after doing this. I hope this also works for you. You can recommend other tools or ways you've found that has freed space for mobile development. It would be cool to add it to the article.
