With latest development tip, when using setPopupDisplayEnabled (true, true, this) on Slider components, my app running on iOS 12 crashes as soon as the slider is touched (when the bubble is to be displayed).
Xcode points to juce_Windowing.mm, line 422: return UIApplicationMain (argc, const_cast<char**> (argv), nil, NSStringFromClass (delegateClass));
with the following error: JUCE Message Thread (1): EXC_BAD_ACCESS (code=1, address=0x105e94000)
At this point, the debugger points out that customDelegatePtr is NULL.
Edit: just figured out I didn’t unrolled the whole call stack. Here’s a screenshot. Unfortunately, my knowledge in JUCE code base is too thin, but something wrong with the draw code of the BubbleComponent itself which doesn’t work anymore with CoreGraphics?
I’ve been running into the same crash on iOS ( ERROR_CGDataProvider_BufferIsNotReadable) but in my case the code that seemed to trigger it (semi randomly, and never inside the simulator) is some juce::Image manipulations, something innocuitous like that (no pointer or pixel manipulations , just drawing from an image into another image):
