In XCode 16, frameworks are not allowed to contain bitcode, so upload of App to App Store Connect fails validation.
This means that it is currently not possible to publish an app to Apple App Store using this library using XCode 16.
See

for possible solutions, but better solution is probably to upgrade to latest version of Zettle SDK.
Is there any plans to upgrade this project to be usable with XCode 16? I could try to upgrade it myself if you could update the instruction of how to do this since they right now are incorrect, they refer to files that does not exist (e.g. Cartfile).
