What is a XIP file?
XIP files are similar to .ZIP and .GZIP files but are digitally signed in order to verify that the contents have not been modified since the creator saved the file. This helps secure the file from any unwanted tampering and disk errors.
The XIP file is commonly used as a secure solution for delivering Xcode downloads. In the past, Xcode downloads have been tampered with in order to install malicious code into user's applications.
