LLDB: Couldn't IRGen expression

Question

When I\'m running a unit test and want to debug something, I set a breakpoint and type for instance \"po myVariable\". The response I get from LLDB is:

error: Co         


        

Answer 1

I was having the same issue using Carthage frameworks, and got the LLDB debugger working again by deleting the Carthage folder in the project root and forcing Carthage to rebuild the frameworks from source:

carthage update --platform iOS --no-use-binaries

Answer 2

you can try with netx command: Depend where you have install swift, in my case is in /opt/swift/

sudo chmod 644 /opt/swift-3.1.1/usr/lib/swift/CoreFoundation/*
