Xcode Message: Message send exceeds rate-limit threshold and will be dropped

For me, this ended up being calling into UIImpactFeedbackGenerator too frequently. I think it's benign, it's just a message from the OS stating it can't satisfy your request for haptics at the frequency you are requesting.

I noticed the same message when using a wheel style Picker widget: scrolling it fast up and down causes this message to appear. I'm curious if anybody knows what and at which level generates this message. For example, can I instruct the Picker to not generate any events until the wheel settles on one of the options? The message is when the wheel is "flying" through the available options, without settling on any of them, due to inertia. There's some interaction with the OS because as the Picker is passing through options (without settling on them) it's providing a gentle haptic feedback, and a soft tick.
