     - you included `SiestaUI` above
     - and you plan to use `ResourceStatusOverlay`
     - and you are using its default initializer instead of providing your own custom UI layout,
 
     …then you’ll need to copy [`ResourceStatusOverlay.xib`](https://github.com/bustoutsolutions/siesta/raw/master/Source/SiestaUI/ResourceStatusOverlay.xib) into your own project.

+    SwiftPM just recently added support for this, and Siesta will add it in the next release.
 
 Please note that Xcode will show _all_ of Siesta’s optional and test-only dependencies, including Quick, Nimble, and Alamofire. Don’t worry: these won’t actually be bundled into your app (except Alamofire, if you use it).
