As per Xcode 11.1 Release Notes, it is a known issue when trying to update to Xcode 11.1. To solve the issue, use the suggested workaround - delete the existing Xcode.app or temporarily change the Xcode.app file extension. Xcode may fail to update from the Mac App Store after updating to macOS Catalina. Xcode - 11.3.1; macOS - 10.14.6; iOS - 14.2; The App Store says I need to have at least macOS 10.15.4 to download the latest Xcode. The upgrade to Big Sur is huge and I'm running fairly low on space on my Mac, so I'd rather just upgrade to Catalina, but I can't seem to find a standalone download (i.e., not an update that requires already having.

Open up Disk Utility — you can use spotlight by pressing cmd+space: Now right click your main hard drive — it is most likely called Macintosh HD and select Add APFS Volume.

How to solve this problem?
Solution no. 1:
I filled a Radar FB6123260 please do that also. For me resetting the nvram worked and deleting derived data.

Solution no. 2:
Add your new files to the compiled bundles as part of the build phases?
Not only does the target need to be set for the file- but it also has to be included in the compiled bundles..
Project -> Target -> Build Phases -> search for the file your are trying to work on
Hope this helps!
Xcode 11 Without Catalina
In this micro tutorial I wanted to cover installing RVICTL after installing macOS 10.15 and Xcode 11. I installed Xcode 11 beta along with the command line tools and fired up the terminal thinking that RVICTL would be available from /usr/bin, but was surprised when I did not see it from the command line. I started to look all over my machine in the usual places but and was stumped. Finally, I found a solution and that is why I wanted to write this tutorial, to share with you that that solution in case you had seen the same problem.
What is RVICTL? RVICTL stands for Remote Virtual Interface Tool, that can start and stop a remote packet capture instance for any set of attached mobile devices. RVICTL is very useful for taking a packet capture or monitoring traffic off of a specific interface on a mobile device.
UPDATE: (9-6-2019) As of macOS Catalina 10.15 Beta 7 and Xcode 11 Beta 7 installing the .pkg by hand may no longer be needed. I installed Xcode 11 Beta 7 on macOS 10.15 Beta 7 and rvictl was available in the Terminal.
Here is the solution. Go to Finder application and hit the Go menu option in the top navigation bar. Next, navigate down to Go To Folder.
Xcode 11 Catalina Update
When the Go to the folder option pops up, add in this path: '/Applications/Xcode-beta.app/Contents/Resources/Packages' Remember if Xcode is not in beta to remove '-beta' from the path on Xocde. Hit go and you should see 4 packages.
Double click to run through the install process for MobileDeviceDevelopment.pkg and for MobileDevice.pkg.
Now from the terminal you should be able to run the rvictl command and see a response recognizing the tool!
That's it! That is all there was to it. Now you are good to run a packet capture and analyze traffic from any of your Apple mobile devices. For more information on how to do so, see my article on packet captures here. Hope you enjoyed this micro tutorial, if you have any questions, comments, or concerns, please leave a comment and I will get back to you as soon as possible. Thanks!
