LLDB warning with v32.x and main

[gutley]

I just switched my fork of the code from being based off v31.x to v32.x (and hence Xcode 12.1 to 12.4). Now the first time I break into the debugger I get:

---

warning: Swift error in fallback scratch context: error: failed to load module 'Client'

note: This error message is displayed only once. If the error displayed above is due to conflicting search paths to Clang modules in different images of the debugged executable, this can slow down debugging of Swift code significantly, since a fresh Swift context has to be created every time a conflict is encountered.

I switched over to main branch and get the same thing.

Just me, or is the 'expected'

The above actually happens the first time a breakpoint is hit in the main app, or one of the embedded frameworks and it really does slow down debugging. e.g I put a breakpoint in MZLocalizedString and then try to just 'po key". It takes a few seconds to output anything
