"No cache exists for this resource: kernel.ios.bundle" in SDK 25.0 detached app

I upgraded my app to SDK 25.0.0, then detached for building with Xcode. The resulted app doesn’t work, giving me error “No cache exists for this resource: kernel.ios.bundle”.

I thought offline JS bundle should be supported by now. Am I missing something?

I’m using exp 49.0.1, SDK 25.0.0. Steps to reproduce

 exp init ...
# modify app.json, update slug, package name etc.

exp detach

exp publish 

cd ios ; pod install

Then open the workspace in Xcode, Archive and export IPA for ad-hoc distribution. Loaded the app onto my phone, then got the error.

Here is a workaround you might be able to use for now:

• Open https://expo.io/@exponent/home/index.exp?sdkVersion=25.0.0 in your browser
• Look at the value for bundleUrl there, and download the file at that url.
• Name the downloaded file kernel.ios.bundle and move it to the directory ios/your-project/Supporting in your detached project.
• Open your detached project in Xcode, right click the Supporting directory in the file tree, “Add files…”, and add kernel.ios.bundle to your project.

The bug you reported is the result of Expo failing to perform this action automatically for you during detach. This workaround should work as long as your project is running SDK 25. You should be able to use the isRemoteJSEnabled: false behavior.

Hopefully I can come up with a fix in the meantime so that you don’t need to do this any more.

In the next (or next-next) release of ExpoKit, we will remove the need for kernel.ios.bundle so this entire class of issues should go away.
