Same problem: Xcode 11.4.1, iOS 13.4.1, app set available from iOS 8.0, running on actual iPhone.Seems to result in blank or misconfigured table cells on 1st launch, but:- blank cell is resolved on subsequent launches, and- misconfigured cells are resolved upon scrolling down then back up.I also converted from Objective-C to Swift and now am getting this message. Hmm... something in the background with loading a xib hanging around?-----Update:I deleted the `Launch Code.xib`, cleaned everything, and rebuilt. I haven't seen the error again so far...Note: I made sure the `Launch Screen.storyboard` was selected in the target's `Launch Screen` setting, and that the `main.storyboard` was selected for the Deployment->Main Interface setting before deleting/rebuilding.

To fix missing Control Center, try: Open System Preferences Open Dock & Menu Bar Scroll down to 'Fast User Switching' Uncheck the box for 'Show in Menu Bar' That enables display of expected Menu Bar items - except Spotlight. Don't know what happened to Spotlight....

Also, Command-Space still opens Spotlight. (I just learned this recently, and it's in System Preferences -> Keyboard -> Shortcuts.

I did this, and successfully got my Control Panel to show. Now, however, I've lost my Spotlight. 2nd note: enabling Fast User Switching in the Menu Bar makes *all* the icons except Siri disappear from the Menu Bar.

The workaround from the release notes - https://developer.apple.com/documentation/macos-release-notes/macos-big-sur-11-beta-release-notes/ (search for "Installer and Software Update") - worked for me - for a little while. Now I'm getting the same error again. Re-doing the workaround didn't help.

Are you a member of the developer program? If so, you should be able to access the download. Also, to enter a screenshot, you should be able to click the link icon in the toolbar below the textbox for your forum post and add your flickr link.

I have the same problem. Weirdly, initially I could only see Spotlight and Siri on the Menu Bar. After going through System Preferences to select the items I wanted to appear on the Menu Bar, nothing showed there. With the Menu Bar right side blank, I found a post here about the Control Panel missing. When I disabled Fast User Switching (in System Preferences under Dock & Menu Bar, scroll down to Fast User Switching, then uncheck Show in Menu Bar) - the rest of the icons appeared (including Control Panel), but not Spotlight. Now, I can't get Spotlight, and I can't remove Control Panel. Sigh... I did make a Feedback Assistant - https://feedbackassistant.apple.com/ report for this... Others might also want to do the same...

Do a search on something like: downgrade from big sur beta to catalina You'll find a number of articles with details. The short of it is to use Recovery to erase your disk, then reinstall MacOS - which will bring Catalina back. Make sure you pay attention to the details given in the articles, though, as there are some steps you don't want to miss.

AFAIK, as long as you're using the regular release version of Xcode, it doesn't matter which OS you're using underneath. You just can't use a beta version of Xcode to distribute apps to the Store. As for the Big Sur beta - ouch! It's got a multitude of problems right now. I agree with @Claude31 that, unless you're really brave and adventurous to be on the cutting (ie "bleeding") edge, you might want to hold off on installing the beta.

Found this similar item on Stack Overflow: How to send an imessage text with applescript, only in provided service? - https://stackoverflow.com/q/11812184/1107226 while searching for something similar. It's old, and I haven't tried any of the answers out, yet, but they look like they'd work...

Thanks for your helpful info, eskimo! Question remains once the Developer ID Application cert is created: is the XXYYYWWW part inside the parens the actual ID?

Anyone? An alternative testing package for Safari? Instructions on how to use Xcode to test web pages in Safari with automation? Edit: looks like I might be able to use XCUITest to automate testing Safari in Xcode. I'll give that a try...
