I am trying to upload an Universal app which supports only Portrait mode. But while uploading the package through AppLoader, it's want me to enable Landscape mode. But I don't want to support Landscape mode in my Application. Please have a look the following image. How to upload an app without having landscape mode?
I know I am late to answer but for someone else who is still looking for answers.
Go to Project Navigator > General Tab > Choose Device Orientation to portrait mode only or whatever you designed.
Secondly, If you are targeting both then use constraints and UIStackView or for large changes use different storyboards.
Thanks for reading it.
