Hello, Would appreciate any help with an issue I am having writing Live Photos. Following the code samples shown in https://developer.apple.com/documentation/avfoundation/cameras_and_media_capture/capturing_still_and_live_photos/capturing_and_saving_live_photos, I cannot add a Live Photo to the camera roll. I get an error code -1. I am able to successfully write the individual image, and movie, so I know its not an issue with the files or a permission issue. I am writing a .jpeg and .mov file. Do Live Photos require to be written with specific file types? Any other requirements for writing a Live Photo? Please if anyone can help I would greatly appreciate it. Thank you

Hello,I have been attempting to archive a project that embeds an iMessage app extension. When I do so I am getting a build error with the mesage "Undefined symbols for architecture arm64:". The error then references a bunch of classes from a framework I have made to share code. I am completely befuddled by this. When building and running debug on an iPad pro, which uses arm64, the app target will build, while the extension will not. On other devices such as my iphone both the app and extension build and run. I believe the framework is building for arm64. Standard Arhcitectures arm7 arm64 is selected, as well as valid architectures arm64, arm7, arm7s. Does anyone have any clue of what is going on. Any help would be greatly appreciated!Thank you,Dylan
