Have a look at this post I made: There might be some workarounds, or at least an explanation of whats wrong
Hello Chongjie,
I’m unable to see the post Samuel is referring to, but there was a Unity/Xcode bug in a previous version that required turning off the Thread Performance Checker that presented similarly.
The workaround for that was to open Xcode and go to Product > Scheme > Edit Scheme to display the scheme editor. Select Run, navigate to the Diagnostics section, and unselect the Thread Performance Checker tool checkbox as shown below.

I don’t have the same setup so I’m unable to verify if this will solve your issue, but it could be worth trying. Please let me know if this works for you.
