First of all, I apologize for the next few days of pain.

Find hot spots with

```sh sudo du -h / | sort -rh | head -20 ```

Steps to take (preferably in order):

• Remove Caches with `rm -rf ~/Library/Caches/*`
• Open Xcode and delete all unused Toolchains
• Open Xcode and delete all simulators
• Remove DerivedData with `rm -rf ~/Library/Developer/Xcode/DerivedData/*`
• Remove Pods in iOS project `rm -rf ~/src/github.com/mobiletoll/ppr-ios-app/Pods/*`
• Clear CocoaPods `pod cache clean –all`
• Remove CocoaPods directory `rm -rf ~/.cocoapods`
• Open AVD Manager and wipe data
• Open AVD Manager and delete devices
• Clear gradle cache with `rm -rf ~/.gradle/caches/`
• Open SDK Manager and delete SDKs
• Reboot to reclaim caches
