Good news! I made a bunch of changes, and now it seems to be working.
To recap, this is a Developer ID codesigned (but not sandboxed, and not mac-app-store) app which includes a helper app.
I wasn’t able to get the helper app to read Photo files when the main app was authorized.
Here’s what I changed:
- instead of testing while running both my main and helper apps using remote debugger, I tested in a fully built and code-signed app.
- Added these plist entries to my main app:
NSPhotoLibraryUsageDescription:"This app can read metadata such as picture title and description when you drag & drop images "
com.apple.security.assets.pictures.read-write:true
com.apple.security.personal-information.photos-library:true- added this plist entry to my helper app:
com.apple.security.inherit:true- Updated to 10.14.1 beta 3 (18B57c)
- when communicating the URL for the file from my main app to helper app, instead of just sending the file URL over IPCSocket, I’m now sending the bookmark data:
Main App:
bookmarkData = CFBookmarkMBS.CreateBookmarkData(theFolderItem)
Helper App:
dim options as Int32 = 0
dim relativeTo as FolderItem = nil
dim isStale as boolean
theFolderItem = CFBookmarkMBS.ResolveBookmarkData(bookmarkData, options, relativeTo, isStale )- used tccutil reset All before testing
- deleted all copies (including leftover debug copies) of my app before testing
Some of these steps may not be required.
Also:
- this is a 64 bit build using the latest Xojo beta
- the main and helper app have different bundle IDs (of the form com.mycompany.main and com.mycompany.helper)
