The QuartzCore.framework is missing in the iOS XCode project export.
Which version/branch are you on? In the modules branch, the frameworks are specified for each module, and Quartzcore is definitely included if you use some of the audio modules.
latest juce/modules. turned off audio modules and saved project, the iOS proj does not have quartscore.
gotta have it in there for iOS if doing any CALayer stuff CoreAnimation etc.
Ah, ok, I didn’t realise that was dependent on it. I guess I’ll add it to the juce_graphics module too.
