Thank-you, NSBob! I was running two versions of the same Mac app. Closing the production one, resolved the problem. No database was involved.

Did you discover an answer?I am receiving this console message using Xcode while testing a Mac app. The app has a drag and drop feature for images. The message occurs only when dropping large jpg images (287 kb, 564kb) but not smaller images, and not large png files (525kb).

For me, it was a spotty internet connection. Once the connection was stable, no problem occurred when rerunning the app. I made no setting changes.

Thank-you! That fixed it for me. Do you know why this fixes this error? I don't understand the relationship between the main queue and this error.

"Invalid parameter not satisfying: [name length] > 0"This error message occurred when I removed the value for key "Storyboard Name" in Xcode 11's info.plist. I was attempting to remove references to Main.storyboard and create the storyboards programmatically. The solution for me was to remove the "Storyboard Name" key/value altogether or add a value to "Storyboard Name" depending on the situation.info.plist/Application Scene Manifest/ Scene Configuration / Application Session Role / Item 0 / Storyboard Name

Yes, as of Xcode 12. From Apple's Xcode 12 release notes: Asset Catalogs New Features Added support for Scalable Vector Graphic (SVG) image assets. These preserve their vector representation with deployment targets of macOS 10.15 or later, iOS 13 or later, and iPadOS 13 or later. (18389814)

These permission errors occurred with a project opened in Xcode 12 beta. Then when opening the project in Xcode 11, everything was fine.

Yeah! Just tried my app on Xcode 12.5 Beta and it's working. On Xcode 12.4 beta the same app will show the errors posted and then crash on code that is something this: SKNode().run(SKAction.playSoundFileNamed(....

It's curious that Apple says a launchScreen.storyboard is required but no longer includes one in Xcode 12's App project template for SwiftUI.

I received the same error. In my case, closing and reopening the project fixed the problem.

After selecting Xcode's menu File->New->File, select View in the User Interface group. View will create a .xib file. (This applies to iOS, MacOS and TVOS but not WatchOS.)

Suggested by an Apple Frameworks engineer: xcrun simctl --set previews delete all My Previews folder was 110GB and went to 6GB. Everything seems to be working well.

This works as well. let _ = print()

I'm having the same problem. Is this only with Intel computers?
