We have a detached ExpoKit SDK 31 app that we are now building using XCode for development builds and using
fastlane build_app for production builds.
On my first production build, I encountered the
Unexpected end of JSON input error for shell-app-manifest.json and did an
expo publish on the command line to resolve this error per Xcode Build Fails on ExpoKit Detachment from SDK29.
Then we found that
expo publish needs to be run before each production build, or else the user will install the build and get a stale JS bundle loaded. Questions:
(1) How can I get
fastlane build_app to include that
expo publish step?
(2) Each time I manually run
expo publish, it results in changes to shell-app-manifest.json, AppConstants.java, and shell-app.bundle, which is not desirable for automated builds. How to avoid this? I read https://docs.expo.io/versions/v32.0.0/expokit/advanced-expokit-topics/#configuring-the-js-url but was not clear on how to change this.
