Also having this issue, and any loops in my iPadOS App are now 15x slower than before, simulator and device. Me and team had to rollback to XCode 13.1 as it is making our development unsustainable in XCode 13.2

I am getting the same crashes only when building the iPadOS App from Xcode 15.1 with Objective-C project. If I go back to Xcode 14.6.1, nothing crashes. From what I can tell, it is crashing in Xcode 15.1 when calling sub viewControllers, whose classes don't have init. This was never an issue for me in years of Objective-C development, where the viewController is called as a child of a presenting modal viewController. Hoping this will be fixed in Xcode 15.2, otherwise I will need to change tens of viewController classes to have empty init methods to patch the issue.

I am still new to all model training tasks, but based on the WWDC 2024, I was also led to understand that conversion and training of models in Apple Silicon would be much faster and viable than before. In so much I traded in my old intel macbook pro for a new M3 pro macbook pro. Yona Havocainen's session "Train your machine learning and AI models on Apple GPUs" this year shows the training in Jupyter Notebooks as fast, and the model query execution instantaneous. I asked Apple Support for clarification on what versions he was using for his packages, macOS, and model were. But the response I got was to look into the forums and videos to which I already watched...
