All of my code is running well on iphone, but is not showing on preview and simulator. I have tried many methods from forum such as using sudo command, but nothing changed yet. Besides, I also reinstalled Xcode 12.5 onto my mac as suggested from forum.
The preview error begins like this, “HumanReadableNSError:…” And the simulator is always black.
Right now I have followed this class to IOS database course with my iphone XR as the simulator. It will be of great help if anyone can solve the preview and simulator problem for me. Thank you!
