Example project to show a bug in Xcode’s new build system related to development pods.

Original Bug Report (Radar #41126633)

Changes in library’s file are not compiled until doing a clean build

Summary:

We have a project structure where we have a library included via cocoapods as a so-called development-pod. Whenever changes are made in a file inside the library they are not re-compiled when building our app. Only a clean build helps to make changes available in the app.

Steps to Reproduce:

Have a project setup similar to our (see the attached example project). Open the attached workspace and run the app. You will notice a crash on viewDidLoad() of the ViewController. There you will see further instructions to experience the issue. For completeness here they are again:

• Run the app
• Experience a fatal error
• Remove the line where the fatal error is created
• Run the app again (NO clean build)
• Observe that the app will still be terminated by the fatal error you just removed
• Do a clean build to finally get rid of the fatal error

Expected Results:

• App does not crash anymore after removing the fatalError from the library

Actual Results:

• App still crashes because of that fatalError
• Breakpoints don’t work either because the source you see and the compiled one are not the same anymore

Version/Build:

Xcode 10.0 Beta (10L176w)

Configuration:

Project with cocoapods integration of self-owned library.
