Waiting for {simulator / device} to start

Question

With Xcode 9.3 (beta), I ran into a problem with the Xcode tool, while I am trying to build / run an application (project) for the first time after starting / starting Xcode.

Several times, it prohibits the assembly of the project with a message in the status bar:

Waiting for iPhone-X to launch

While my simulator is already running and working (no activity occurs in the simulator).

Here is the snapshot link:

As a workaround, I force close Xcode (9.3) and restart.

Does anyone have the same issue with Xcode 9.3 beta?

Update : The same issue in Xcode 9.3-Beta 2 as well.
