In the case of my project, it was caused by the inclusion of a [CommonCrypto] wrapper which was included as a framework in one of my modules. From what I understand, this caused some conflict with the crypto modules now included with iOS
This is a long-lived project and this CommonCrypto framework is now deprecated for us by the facilities provided in more recent Apple frameworks. With the CommonCrypto framework removed debugging started working again.
I'm facing the same issue in a framework. I'm building a framework with both Obj-C and Swift code. I'm integrating this framework into an App using cocoapods by mentioning a local path in the podfile.
When I run the app, If I put breakpoints in swift files in the framework, I'm not able to see the variable values. But If I put breakpoints in Obj-C files everything works fine. The breakpoints work fine even in swift files in the app. It's only the swift files in the framework.
I've tried everything you mentioned and I'm not using CommonCrypto framework. Any help would be appreciated.
Can you give me any pointers on how to find the culprit framework? I'm not using commoncrypto, but if you can tell me where to look that will be very helpful.
