Under Xcode 10, lldb will often fail to stop at breakpoints in non-main targets. For instance, when debugging an iOS, breakpoints set in the Xcode UI in a framework target may not be hit. Additionally, breakpoints set in Xcode 10 are show as unknown in Xcode 9.4.1.

Steps to Reproduce:
1. Add breakpoint in non-main module that you know will be hit.
2. Run app configured in way that should trigger breakpoints. 
3. See no breakpoints hit.

Expected Results:
Breakpoints always hit.

Actual Results:
Breakpoints not always hit.


These modules are integrated through CocoaPods.



I'm having the same problem, but without CocoaPods. I have a workspace with a framework project and an example app project which embeds the framework. Breakpoints in the example app are working, but breakpoints inside the framework are never hit. It seems to be intermittent for me as well.

Has anyone heard an update or found a work-around to this?
