Hello, My App works well on iOS17 and previous iOS18 Beta version, while it crashes on latest iOS18 Beta5, when it calling model predictionFromFeatures.
Calling stack of crash is as:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Unrecognized ANE execution priority MLANEExecutionPriority_Unspecified'

And my model file type is ml package file. Source code is as below:
//model
MLModel *_model;
......
// model init
MLModelConfiguration* config = [[MLModelConfiguration alloc]init];
config.computeUnits = MLComputeUnitsCPUAndNeuralEngine;
_model = [MLModel modelWithContentsOfURL:compileUrl configuration:config error:&error];
.....
// model prediction
MLPredictionOptions *option = [[MLPredictionOptions alloc]init];
id<MLFeatureProvider> outFeatures = [_model predictionFromFeatures:_modelInput options:option error:&error];
Is there anything wrong? Any advice would be appreciated.
