When we try we get this error Unable to create shader debug session source is unavailable under the target's build settings, ensure the metal compiler build options produces debugging information and includes source code Just downloaded xcode 26 and i see build fails despite metal toolchain 26.0 downloaded Cannot execute tool 'metal' due to missing metal toolchain Overview to debug your shaders in xcode, configure your build to include shader source code by changing your project’s build settings Select your project in the project navigator, click the build settings tab, and search for the produce debugging information setting in the metal compiler build options section.
When you develop complex software, you inevitably run into bugs and performance issues Though xcode and instruments can provide deep detail about what’s going on, often some basic information is enough In this episode i’m going to cover simple yet powerful tools that xcode provides for metal diagnostics. Fb7731230 note that, this sort of control flow can confuse the compiler and lead to issues debugging metal shaders So you may want to pull this out if you have trouble attaching a debugger Article building your app to include debugging information configure xcode to produce the symbol information for debugging and crash reports
