+### Running Detox in a Rosetta environment
+
+When working with dependencies that require running your iOS app in a Rosetta simulator, you may encounter issues with the `detox build` command. These issues often relate to SwiftEmitModule or SwiftCompile errors. To resolve this, follow these steps:
+
+1. Modify your build command in the Detox configuration:
+
+```json
+"build": "xcodebuild -workspace ios/MyApp.xcworkspace -scheme MyApp -configuration Debug -sdk iphonesimulator -arch x86_64 -derivedDataPath ios/build"
+```
+
+2. Run the following command in your terminal to ensure Xcode is properly selected:
+
+```bash
+sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
+```
+
+3. Launch the iOS simulator in Rosetta mode:
+
+```bash
+arch -x86_64 /Applications/Xcode.app/Contents/Developer/Applications/Simulator.app/Contents/MacOS/Simulator
+```
+
+After following these steps, the `detox build` command should run without errors in your Rosetta environment.
