The iOS module template/location changed with
TIMOB-25195. Now, newly created modules are not able to be packaged in Studio.
Steps to reproduce issue
1. Create a new iOS module
2. Package that module
The module is able to be packaged and packages successfully
The packaging buttons are greyed out
Changing the 'ios' folder back to 'iphone' will allow the module to package, so I believe the location Studio is checking for the iOS module needs updating.
