I'm running Xcode 12 beta 6 on a DTK machine and just upgraded to Big Sur beta 6 released today. When I build and run my Catalyst app for Mac, it fails with

Code Block The operation couldn’t be completed. (OSStatus error -10670.)

In the detail panel, I get

Code Block Details
The operation couldn’t be completed. (OSStatus error -10670.)
Domain: NSOSStatusErrorDomain
Code: -10670
User Info: {
    "_LSFunction" = "_LSOpenStuffCallLocal";
    "_LSLine" = 3664;
}
--
System Information
macOS Version 11.0 (Build 20A5364e)
Xcode 12.0 (17210.1)

I've tried a number of things -- rebooting, reinstalling the command line tools, making sure xcode-select points to the right place. I'm stumped. The app runs as expected under the simulator.

This change occurred this afternoon with the install of Big Sur beta 6 upgrading from beta 5.

Any pointers appreciated!

thanks,
jay

I'm seeing the same thing here as well.

I saw this before with Big Sur b5 and a previous seed of Xcode 12 so I'm hoping that Xcode 12 b7 is released quickly with the needed updates to fix the issue.

Seeing the same. Wondering if this in Xcode 12 Beta 6 Release Notes (https://developer.apple.com/documentation/xcode-release-notes/xcode-12-beta-release-notes) could be the cause:-

A Mac Catalyst app signed to run locally on macOS may fail to run with the Mac (Rosetta) run destination. (64421496)

🤔

UPDATE: It's also in Big Sur Beta 6 Release Notes under Xcode Known Issues :-

You're currently unable to launch Mac Catalyst and iOS apps using Xcode. (67356581)

So, I guess that settles it for now.

Xcode works for me, but any of my own apps won't launch with this error.

I have tried targeting Rosetta, MyMac, and local. I am code signing with a dev cert (Not run local).

I am having the same issue, but I'm getting a different error code - 10810.

I'm trying to update a traditional Mac App. I can't get the application to launch from Xcode, but if I open the Finder and double-click the software opens like it should. From there, I can attach to the process in Xcode. This allows me to keep working, but I'd like to find a real solution to the problem.

Has anyone gotten any other insights into fix or work-around?
