How do you add documents to file folder in swift preview

Hi,

I am trying to make an app where a user needs to select a document from the file folder on iphone. I was wonder how do populate this folder with moc documents so that I can preview the functionality on preview and simulator. When i try to drag and drop it does not work and when I try to share file with simulator it does not load it just takes me to the iMessage app in the simulator?

Thanks
