Invalid Swift Support/Invalid Implementation of Swift

Invalid Swift Support / The SwiftSupport folder is empty

important note: this only works for projects that do not use swift, see comment below

Invalid Swift Support - The SwiftSupport folder is empty

This issue has been resolved by setting the deployment target same for all extensions added in project.

Initially RN project having 11.0 deployment target and newly added watch having latest one 13.0 so swift folder is not created automatically. after modifying all to 12.0, it works automatically without doing any manual step.

This issue has now be resolved, there is a new version of the Titanium SDK, 6.0.1.GA that specifically has a fix in for this issue. I have now created, submitted and have a Titanium app with associated watch app now published in the app store.
