Explore Apple platform development across iOS, macOS, iPadOS, watchOS, and visionOS: shared frameworks, key differences, cross-device strategy.
watchOS 27 puts Foundation Models and the Vision framework on the wrist. The capability is genuinely new. Whether you should use it is a harder question, and Apple's own examples hint at the answer.
Most of iPadOS 27 is shared platform work that also arrives on iPhone and Mac. One thing in it is genuinely structural to the iPad, and it's the one nobody led with.
The honest question about visionOS isn't what's new. It's whether the work pays for itself, and visionOS 27 changed that arithmetic in a way the feature roundups mostly skipped.
The migration guides all stop at the point your App Intent compiles. That's the moment the interesting failures begin and they're silent, which is why Apple shipped a framework specifically to catch them.
Swift Testing has matured. Here's a side-by-side syntax comparison, the specific cases where migrating costs more than it's worth, and why the interop improvements matter more than any single feature.
