Xcode 12.0 (universal binaries version) freezes during workspace navigation

Xcode 12.0 (universal binaries version) is frozen most of the time. Looks fine while building, but any workspace navigation (e.g. open schema) takes a lot of time while Xcode stays frozen. Does anyone experience something like that?

What kind of hardware are you using? Also, can you take a spindump of Xcode while it appears to be frozen and file a Feedback? You can take a spindump from Activity Monitor by doing the following:

  1. Select the process (e.g. Xcode)

  2. From the View menu select "Run Spindump"

  3. Then attach the result to your Feedback.

Ok, it seems Xcode starts to hang after adding ~15 targets into a single scheme. More targets => longer hangs.
