Hello, it took me a while to work out the flow for testing my app with Testflight. At first I did ‘exp detach’ in a release branch, then I did a build in Xcode and then an Archive. Then in Xcode I uploaded the archive to the App Store. Then finally in iTunes Connect → TestFlight I could add testers to the build. This worked fine until I came to do an update to the build. I went through the same steps as before and updated the app in my TestFlight app on my mobile device to the new build version, but I wasn’t seeing my code updates. This was very frustrating. In the end after reading this again - https://docs.expo.io/versions/v27.0.0/workflow/publishing
“The standalone app knows to look for updates at your app’s published url, and if you publish an update then the next time a user opens your app they will automatically download the new version. These are commonly referred to as “Over the Air” (OTA) updates, the functionality is similar to CodePush, but it is built into Expo so you don’t need to install anything.”
I realised that by doing ‘exp publish’ or just Publish in Expo XDE then it would update the app in TestFlight.
So my questions are, at what point would I need to do a new release through Xcode rather than just doing publish all the time? and what happens when I do a production ready release? what is the flow for doing updates in production? are there any further guides on this process?
