Xcode clear cache and redundant certificates (deriveddata file, profiles certificate)

Xcode clears the cache, cleans up redundant certificates

1. Remove redundant certificates from Xcode provisioning profile
Manual removal:
Xcode8 Provisioning Profile Path:
~/library/mobiledevice/provisioning Profiles

2. Clean up the cache garbage generated by Xcode compilation project
(Xcode takes a long time, will generate a lot of project compile cache, occupy a large amount of hard disk space (I am more than 10 g when I clean up), need to clean up this directory)
Manual removal:
Xcode compiles the project cache garbage directory:
~/library/developer/xcode/deriveddata

Can be opened in Xcode, Xcode->preferences->locations->deriveddata, delete
Figure below



* 3. These files are hidden files that can be in the terminal
CD LIBRARY,CD MobileDevice, open Provisioning profiles opened and deleted.
