What problem does it solve? Testing apps with custom native code requires a development client, but configuring EAS Build profiles, signing credentials, and distribution to physical devices is error-prone and time-consuming. ## Core Features & Use Cases - EAS Build Configuration: Set up eas.json with a development profile using developmentClient, autoIncrement, and remote app version source. - TestFlight Distribution: Build iOS dev clients and submit them to TestFlight in a single command for team testing on physical devices. - Local Builds: Compile iOS and Android development clients locally and install them via simctl, ideviceinstaller, or adb. - Use Case: Your app adds a local Expo module with custom native code that Expo Go cannot run. Use this Skill to build a development client, distribute it via TestFlight, and connect it to your local Metro bundler. ## Quick Start Build an iOS development client with EAS and submit it to TestFlight so I can test my native code changes on my iPhone.
