Symbol not found: kUTTypeImage

When use with UIDocumentPickerViewController do:

import MobileCoreServices

let type = String(kUTTypeImage)
let documentPickerViewController = UIDocumentPickerViewController(documentTypes: [type], in: .import)

Obligatory Swift answer:

import MobileCoreServices

Look up the symbol (kUTTypeImage) and locate the image/library it should exist in (MobileCoreServices.framework in this case). Then link your binary with that framework.
