An app that renders using the Apple Metal API into the window.

To build the app using the build.sh script, follow these steps:

1. Open a terminal or command prompt.
2. Navigate to the root directory of the project.
3. Run the following command to build the app without running it:

./build.sh

This command will execute the build.sh script and initiate the build process. However, it will not run the app. If you want to run the app after building it, use the command ./build.sh run.

4. Wait for the build process to complete. Any errors or warnings will be displayed in the terminal.

To build the shader files using macOS Metal and xcrun -sdk, follow these steps:

1. Open a terminal or command prompt.
2. Navigate to the root directory of the project.
3. Run the following command to build the shader files:

xcrun -sdk macosx metal -c Shaders.metal -o Shaders.air

This command will compile the Shaders.metal file and generate the corresponding intermediate representation file Shaders.air.

4. If you have multiple shader files, you can include them all in the command by separating them with spaces:

xcrun -sdk macosx metal -c Shaders1.metal Shaders2.metal -o Shaders.air

To further compile the intermediate representation file (Shaders.ir) into a final Metal library (Shaders.metallib), you can use the xcrun -sdk macosx metallib command. Here's how you can do it:

1. Open a terminal or command prompt.
2. Navigate to the root directory of the project.
3. Run the following command to compile the intermediate representation file into a Metal library:

xcrun -sdk macosx metallib -o ./built/Shaders.metallib ./built/Shaders.ir

This command will compile the Shaders.ir file and generate the final Metal library Shaders.metallib in the ./built directory.

4. Wait for the compilation process to complete. Any errors or warnings will be displayed in the terminal.

Once the compilation is successful, you can use the generated Shaders.metallib file in your app by referencing it in your code or build process.

Remember to update your build script or build process to include the compilation of the intermediate representation file into a Metal library using xcrun -sdk macosx metallib.
