I have previously been able to upload multiple versions of our app (built in flutter) to TestFlight and the App Store. However now, seemingly randomly, I cannot even validate or distribute any archive generated in order to upload it to App Store Connect. The error being displayed is as follows App Store Connect Operation Error: No architectures in the binary. Lipo failed to detect any architectures in the bundle executable. From extensive googling, I have tried the following solutions to no avail: Updating to the latest XCode (Version 12.5.1) Removing pod folder and re running pod install Enabling bitcode - can't even build the archive as this causes other errors Restarting XCode Setting all frameworks as "Do not embed" Help! I'm at a loss, and really need to get this uploaded today!
