+# WebRPC Swift Client Example
+
+This example shows generating a Swift client from [service.ridl](./service.ridl)
+using the local generator templates.
+
+## Usage
+
+Regenerate the tracked client:
+
+```sh
+make generate
+```
+
+Build the Swift package:
+
+```sh
+make build
+```
+
+The schema includes representative cases for generated enum fallback naming,
+method/type name collisions, and fields excluded with `json = -`.
