I am following the SwiftUI Tutorial from developer.apple.com site and when I try to preview some files that I created in th project it shows me an error message "Failed to build LandmarkList.swift" followed by an info icon saying "Compiling failed: no type named "LandmarkList_Previews" in module Landmarks". When I hit Try again button it keeps not showing and just giving the same error message.

I have already:

- deleted the Xcode 10 version that I had installed.

-closed and openned Xcode 11 beta

Im running on MacOS Catalina Beta version 10.15.

Somebody please

This problem is still occurring for me:

Code Block NoBuildableEntriesError: active scheme does not build this file
Select a scheme that builds a target which contains the current file, or add this file to a target that is built by the current scheme.

I have macOS Big Sur (11.4) What helped me is related to the fact I copied my project from another Mac. I have quit Xcode, then right clicked the project folder in Finder > Get Info > Unlock padlock in the bottom, right corner of the window that opened, I expanded Sharing & Permission section > selected my username which says Read & Write > Apply permissions. This effectively gives me / fixes full access right to the folder and fixes the problem.
