Hello,
i just started working on a project based on an older Juce version (3.x ?) containing JuceHeader.h and AppConfig.h. The header file is absolutely needed for the project to compile.
Is it safe/possible to keep using these Headers with newer versions or would you recommend to change all the affected references?
Are you on a slow computer? We had similar issues a while back where xcode would randomly not pick-up all the changes we write to the project. We had to add this nasty workaround. We were never really sure what the underlying cause of the bug was. Can you try increasing that wait time in that sleep?
