    reference implementation.
 
+## Example: iOS 18 `int8_both`
+
+This variant uses int8 weights for multiple stages on iOS 18.
+
+Bundle these files in your app:
+
+```
+Resources/
+  coreml_ios18_int8_both/
+    duration_predictor_mlprogram.mlpackage
+    text_encoder_mlprogram.mlpackage
+    vector_estimator_mlprogram.mlpackage
+    vocoder_mlprogram.mlpackage
+  voice_styles/
+  embeddings/
+  onnx/
+    unicode_indexer.json
+    tts.json
+```
+
+In the Swift demo app, update the CoreML folder name to point at
+`coreml_ios18_int8_both` (the app defaults to `coreml_int8`).

 ## Choosing a variant
