Which of the Vision framework‘s support for grounding/bounding boxes/segmentation carry over to the iOS 27 on-device Foundation Model image support?

With different VLMs supporting different size and background color if padding is needed… and iOS 27 AFM being the most flexible… the previous talk mentioned that the context size suffers for this flexibility… so what’s the best format/size/background for the app to pre-process to minimize token use… much thanks

Any guidance if we want the iOS 27 SystemLanguageModel to always defer to our app for all answers and not its built-in training for responses

Is the PSM UUID format is less stringent than the BLE Service and Characteristic UUID? In our BLE cluster we broadcast both for different tasks... is a GATT and L2Cap mixed cluster of Apple devices ok?

Are there any restrictions/advice/suggestions on how CarPlay supports the Siri changes in iOS 27?

With the restrictions on conversational apps in iOS 26.4... are there any suggestions on how to integrate location services with iOS 27?

What should be the .mode and .options ?

FB21772424 On any iPhone or iPad running 26.3 beta 3 with UIFileSharingEnabled enabled via Xcode, a file cannot be manually copied to/from macOS or manually deleted from Finder but 26.3 beta 2 works fine running on any iPhone or iPad. The version of macOS is irrelevant as both macOS 26.2.1 and macOS 26.3 beta 3 are unable to affect file changes via macOS Finder on iPhone or iPad running 26.3 beta 3 but can affect file changes via macOS Finder on iPhone or iPad running 26.2.1 Thank you.
