The problem is with the reference to ResearchKit.xcodeproj. So first remove the existing reference to ResearchKit.xcodeproj. Select delete > remove reference. Then move the main ResearchKit folder to your App folder. Then Drag and drop ResearchKit.xcodeproj from the ResearchKit folder into the navigation pane of your app in Xcode, under your main project. Finally Embed ReserachKit.framework into your App; Add ResearchKit under Target > General > Frameworks, Libraries and Embedded Content
