Running Xcode 27's Agent and Antigravity Side by Side: Designing the Work Boundary for iOS
With Xcode 27 bringing agentic coding into the IDE itself, iOS development now has two code-writing agents over one repository. Here is a practical design for keeping a single source of truth and splitting work across spec, implementation, and verification.
Why Antigravity Agents Build Your Xcode Project Fine One Day and Break It the Next on a Synced Folder
Put an Xcode project inside a Dropbox-synced folder, hand it to an Antigravity agent, and builds start passing and failing at random. Here is the real cause — sync daemon versus build — and how to fix it with xattr exclusion and a conflict-copy preflight.
