i have just downloaded Xcode 11 beta and installed in a vm environment. When trying to start a new playground or project, xcode quits with following error code. Any idea how to solve ?

It is fixed in XCode 11 beta 2, available on developer.apple.com !!!
June 17 2019.
- You don't need MacOS Catalina, only Mojave 10.14.4 and up (current is 10.14.5).
- I used VMware on Windows to install Mojave and XCode beta 2.

This should probably be a comment, not an answer, but I lack the reputation to do so. Here is the xcode developer who developed the minimap indicating that while the minimap indeed does require metal, xcode should not crash when metal is not available. Hopefully he implements a patch to fail gracefully in one of the next builds. As of right now, there is no workaround. The reply to the thread:
defaults write http://com.apple .dt.Xcode DVTTextShowMinimap -bool NO
does not prevent the crash, as mentioned there.

I attempted the same with Parallels (with tools installed), and also observed a crash. I suspect the problem is with the virtualization software lacking support for Metal. Notice the stack trace on the main thread:
0 com.apple.dt.SourceEditor 0x0000000120ccb5cb specialized static MinimapMetalLinesLayer.defaultDevice() + 491 1
com.apple.dt.SourceEditor 0x0000000120cc959c MinimapMetalLinesLayer.init() + 284
The "Minimap" is a new feature in Xcode 11, it's a birds eye view of the source code in a column on the right (similar to Sublime text edit). Also notice the mention of Metal, Apple's graphics API. To test this theory, I opened Xcode 10 (in the same VM) and attempted to build one of Apple's examples. I got the following error, which seems to confirm my suspicion that Parallels is unable to support apps using Metal.

I haven't attempted installing macOS Catalina / Xcode 11 in VirtualBox, VMWare, et al. but unless they support Metal then this crash will happen there as well. If you're testing out Catalina (which is required for SwiftUI on macOS), unfortunately it seems the solution at this time is to install on a spare device or dual boot.
