title: Xcode project with multiple targets and multiple assets catalogs
body: <p>I have a project with two targets: target A and target B. This targets generate app which are "equal" but whit different skins (different colors and images)</p>
  
  <p>For this, the project has two Asset Catalogs, which are identical but have different images insides. Each Asset catalog is assigned to the corresponding target.</p>
  
  <p>This works perfectly and I can generate both applications, but while editing the Storyboards and assigning the images I can only see the images from the first Asset Catalog.</p>
  
  <p>Is there any way to see or "preview" the storyboards with the different Catalogs?</p>
