Xcode 27.2 Introduces an Agent- and Merge-Friendly JSON Format for Project Configuration
Apple's Xcode 27.2 rewrites project config for AI agents—not just humans. JSON replaces property lists; agents can now read and modify build settings without parsing brittleness.

Why it matters
Apple is optimizing developer tooling for agentic workflows by replacing Xcode's opaque property-list configuration format with structured JSON. This signals the IDE ecosystem shifting to agent-native data structures—practical for autonomous refactoring and build modification, but adoption depends on broader Xcode user migration and agent reliability in production.
