- Code completion, on device model specifically trained for swift and apple SDKs
- Swift 6, fully data race safety
- Can enable all “upcoming” features in Xcode build settings now
- Then change the swift version build setting when ready
- Previews
@Previewable attached to prop wrappers, so writing wrapper views is no longer necessary. Useful to preview items that take bindings, for example.@PreviewModifier Useful for mocking environment objects that provide data via expensive tasks, like api calls. Or good for swift data model containers- Faster than ever, due to shared build products
- Explicit modules. An opt-in more parallelized build ordering.
- New unified stack trace view, have to enable it in the debug bar
- 3D scene debugger
- Swift Testing
@Test on any function.
#expect(a == b)- More detailed value inspection on failures
- Quick action: test again, re-runs last test
- Can also set arguments, for parameterized tests. And have test suites. And have tags.
- New flame graph in instruments
