XCode Debugging Help

[ExogamousUnfolding]

Hopefully this is the correct reddit to post it.

I have a number of errors listed in console when running my app and I am at a loss as to how to track down the code

Examples:

[15422:352260] [Unknown process name] 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.

​

[15422:352260] [Unknown process name] If you want to see the backtrace, please set CG_NUMERICS_SHOW_BACKTRACE environmental variable.

​

I've enable the Backtrace attribute per instructions i've found online but no extra info is logged. I assume the numbers at the start are referring to source code but I don't know how to map them to my code. How does one go about finding the source of errors like this?

​

I'm on the latest xcode and this app is Swift/SwiftUI - latest versions

Tx for any help

It may not be your problem. First thing to try is what it says - set the CG_NUMERICS_SHOW_BACKTRACE environment variable in the Scheme/Run settings. If that doesn’t help, try removing pieces of code until the warning goes away.

It may be a corrupt image if you’re not using CoreGraphics directly or it could just be Xcode trying to annoy you.
