Built with SwiftTUI.
The framework already runs real, non-trivial apps — and runs the same one on every host. Below: one component gallery rendered five ways, then maintained example apps in swift-tui-examples you can clone and run with a single command.
One gallery. Every host.
These are not four apps — they are the same SwiftTUI component gallery, the same Views, handed to a different host. The framework owns the cells; each host owns its chrome.

Built in the open.
Maintained example apps in swift-tui-examples — clone the repo and they all build and run with one command.
