First, as of jan 2025 this problem still exists with xcode 16.2 running on the simulator for iphone and ipad.
Second, I see the same message in a simple app with pure objc code whenever I long press on a text field:
Error: this application, or a library it uses, has passed an invalid numeric value (NaN, or not-a-number) to CoreGraphics API and this value is being ignored. Please fix this problem.
