we have written a QL preview generator for some 3D data formats not supported by the AR Quicklook generators included in iOS. however, we are struggeling with the 100 MB memory ceiling imposed on an app extension in iOS. we have included the "Increased Memory Limit" entitlement in both the app and in the preview extensions. nevertheless, the preview generator is limited to 100 MB, even on most recent devices like iPhone 16 Pro Max. we can even see 100 MB limit when we attach to the process with Xcode. my question: did we miss anything? are there additional steps necessary to obtain the increased memory limit? must we explicitly apply for it? 500 MB would be fine (our preview generator does not load textures). best regards

PLATFORM AND VERSION iOS Development environment: Xcode 16.2, macOS 15.3.1 Run-time configuration: macOS 15.3.1 DESCRIPTION OF PROBLEM in MacCatalyst UIDocumentInteractionController does not present a document preview, does neither generate a document UTI nor a document icon. All-in-all UIDocumentInteractionController appears to be unimplemented in MacCatalyst although it is marked available MacCatalyst 13.1+ in the docs. STEPS TO REPRODUCE we have submitted a test project illustrating the issue in FB11826362 run the test project on an iOS device --> it will return document UTI, icons, and present a document preview. run the test project on MacCatalyst --> it will crash at the assert() of the document UTI
