In the video here, the speaker refers to MPSGraphTool, which is supposed to convert from CoreML and other formats to the new MPSGraphPackage format. Searching for MPSGraphTool on Google returns only that video, and there is no mention of it on the forums here or elsewhere. When can we expect the tool to be released? How can we find out more information about it? My use case is that the ANECompilerService that runs on the Mac / iOS devices to compile CoreML Models / Programs is extremely slow and unreliable for large models. It often crashes entirely, sitting at 100% CPU usage forever and never completing the task at hand, meaning the user is stuck in a loading state. This also applies in Xcode when running a performance test. I would really like to compile the graph once and just run it on device directly.

My team and I have been working on production iOS apps since 2014, but today in 2021 we have an issue we can't figure out. We have been working on a major feature which we are now at the point of internal alpha testing. We have two test apps: one of the specific section of the app the feature is in, and one of the entire app. In both of these apps, our local builds work without issue in both Debug and Release configurations. However, all of our TestFlight builds (we only do TestFlight builds of the complete app) are crashing all on devices we try it with as soon as the new feature is used. The crash reports point to a 3rd party library we are using regarding buffer sizes (it is an audio feature, using low level I/O AudioUnits). This doesn't really help us track down the issue though because, try as we might, we have never been able to reproduce this in a local build. There it always works without failure. I don't actually understand how this is possible. What could possibly be different between a Release build run locally compared to what is available on TestFlight? Another side of this is, can we somehow debug the TestFlight build on our devices with lldb in order to track down what is going on here?
