When should I use a development client instead of Expo Go?

Use a development client when your app requires custom native code, local Expo modules, or third-party libraries not included in the standard Expo Go app.

Can I submit my dev client to TestFlight automatically?

Yes, the skill guides you through building and submitting to App Store Connect in a single command using EAS Build.

Can I build my development client locally?

Yes, this skill provides commands for local builds on iOS (requires Xcode) and Android using the --local flag with EAS CLI.

How does this skill help with EAS configuration?

It ensures your eas.json is correctly set up with development profiles, including critical settings like developmentClient: true and autoIncrement.

What should I do if my build fails with signing errors?

The skill provides troubleshooting steps, specifically suggesting the 'eas credentials' command to manage and fix signing certificates.
