• Predictive code completion boosts your productivity when writing Swift code, using a code intelligence model that keeps your code private and works even when you’re offline
• Swift 6 makes it even easier to write safe concurrent code with a new language mode that analyzes your code at compile-time and diagnoses possible data races
• Swift Testing simplifies writing tests with features like parameterization to run the same test over a series of values, and tags to flexibly organize your tests
• Previews can share environments or data across your app and use property wrappers within preview blocks
• Explicit Modules provides better build parallelism, better diagnostics, and faster debugging
• Unified backtrace view shows relevant code from all stack frames in a single view
• Thread Performance Checker surfaces runtime issues and performance problems, including diagnostics to identify excessive disk writes
• RealityKit Debugger captures snapshots of a running visionOS app entity hierarchy to explore it in 3D
