# Add build configuration parameter to enable `Debug` or `Release`
builds

## ♻️ Current situation & Problem
As of now, there is no option to adjust the build configuration of the
`xcodebuild-or-fastlane.yml` GitHub Action.
This functionality would be very useful, especially for important
production builds or repos that rely on low-layer Swift functionality.


## ⚙️ Release Notes 
- Add build configuration parameter to `xcodebuild-or-fastlane.yml` to
enable `Debug` or `Release` builds


## 📚 Documentation
Proper documentation of parameter


## ✅ Testing
Tested with the `SpeziLLM` action:
https://github.com/StanfordSpezi/SpeziLLM/actions/runs/7607351909
