Xcode's Constant Phone Home: A Privacy and Performance Nightmare
2025-03-01
Developer Jeff Johnson discovered that Xcode frequently connects to Apple servers during project builds, causing slowdowns. Using Little Snitch, he identified `developerservices2.apple.com` as the culprit; disabling connections to this domain dramatically improved build times. Further investigation revealed that Xcode also connects to other Apple servers, such as `devimages-cdn.apple.com` and `appstoreconnect.apple.com`, upon launch and project opening. These connections appear unnecessary and may involve the collection of developer data. Johnson argues that this behavior compromises developer privacy and recommends disabling unnecessary network connections.
