To get started, you need a Mac, Xcode 16.4+ (iOS 17.0+ deployment target), and a (free) Apple Developer Account.

1. Install Dependencies

1. If your Xcode installation is fresh, make sure that command line tools are selected:

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

2. Install the tools needed to build the project:

   brew install xcodegen swiftformat swiftlint
   

   (If you don't have Homebrew, see their official install instructions.)

3. Download the llama.cpp XCFramework (required for on-device LLM features):

   ./scripts/bootstrap-llama.sh
   

2. Setup Project

1. Generate the Xcode project from project.yml:

   xcodegen generate
   

2. Open Sayboard.xcodeproj in Xcode

3. For both the Sayboard and SayboardKeyboard targets:

1. Build and Run (Cmd+R)

Bug Reports and Questions

Settings has a Report a Problem section that opens either a prefilled GitHub issue or a prefilled email, whichever you prefer. Both carry the app version, the iOS version and the device identifier, so the report arrives ready to work on.

You can also write directly to support@sayboard.app.

Sayboard doesn't collect any analytics or telemetry, so we rely on your feedback to find and fix problems.
