I can confirm the issue exists using the latest iOS 18.2 release. In my application, I have mlpackages being loaded using .cpuAndNeuralEngine and we only started receiving this error message after updating to 18.2. It doesn't appear to impact usage of the models, but it's weird that it shows up only in 18.2.

Same issue. Just started about 20 minutes ago for me after Xcode 26 & macOS 26 were working fine for several hours.

@DTS Engineer none of those suggestions worked for me unfortunately
