DTK, Xcode 12 beta, no simulators

I am trying to run a simulator on the DTK without success.
They do not appear. I have downloaded the runtime.

Running "xcrun simctl list runtimes" gives the following:

== Runtimes ==

iOS 13.5 (13.5 - 17F61) - com.apple.CoreSimulator.SimRuntime.iOS-13-5 (unavailable, failed to open liblaunchsim.dylib)

iOS 14.0 (14.0 - 18A5301v) - com.apple.CoreSimulator.SimRuntime.iOS-14-0 (unavailable, failed to open liblaunch
sim.dylib)

So why can't "liblaunch_sim.dylib" be launched?
iOS Development is not supported on the DTKs at this point.
Is there any estimate on when or if iOS Development will be supported on the DTK?
It looks as if Xcode beta 3 supports iOS 14.0 simulators but no earlier releases. Am I correct?
Actually, it worked for me on Xcode Beta 3, but when I moved to beta 4, I couldn't get the devices working, getting the same error as andytomg. Hope it'll be fixed soon!
XCode Beta 4 supports earlier simulators but you have to go into Preferences > Simulators and explicitly download the 13.x ones you want.
Can you give an update on this, @jeremyhu? i.e. if and when IOS development will be supported. Is there an official statement on this? The whole point for us is to be able to port our IOS apps to native Mac, (a single codebase where we can), and not having half of that Dev environment is going to be *really* limiting.
