A sample SwiftUI app using whisper.cpp to do voice-to-text transcriptions. See also: whisper.objc.

First whisper.cpp need to be built and a XCFramework needs to be created. This can be done by running the following script from the whisper.cpp project root:

$ ./build-xcframework.sh

Note: if you get the error "iphoneos is not an iOS SDK" then you probably need to run this command first:

sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

Open whisper.swiftui.xcodeproj project in Xcode and you should be able to build and run the app on a simulator or a real device.

To use the framework with a different project, the XCFramework can be added to the project by adding build-apple/whisper.xcframework by dragging and dropping it into the project navigator, or by manually selecting the framework in the "Frameworks, Libraries, and Embedded Content" section of the project settings.

1. Select a model from the whisper.cpp repository.¹
2. Add the model to whisper.swiftui.demo/Resources/models via Xcode.
3. Select a sample audio file (for example, jfk.wav).
4. Add the sample audio file to whisper.swiftui.demo/Resources/samples via Xcode.
5. Select the "Release" ² build configuration under "Run", then deploy and run to your device.

Note: Pay attention to the folder path: whisper.swiftui.demo/Resources/models is the appropriate directory to place resources whilst whisper.swiftui.demo/Models is related to actual code.
