I guess i still haven't understood something about sandboxing or entitlements.
I am trying to access the user's ~/Pictures folder, and also create a
security-scoped bookmark (SSB) for that folder.
Under the target's Signing & capabilities section, File Access Type, I have set
"Pictures Folder" to read/write.
Getting the path using this
NSURL * pic_dir = [ [NSFileManager defaultManager] URLForDirectory:
NSPicturesDirectory
inDomain:
NSUserDomainMask
appropriateForURL: nil
create: NO error: &err];
and doing a spotlight search over the folder works just fine.
However, creating a SSB for pic_dir does not work.
I am trying to create it like this:
NSData * dir_bookmark = [dir bookmarkDataWithOptions:
NSURLBookmarkCreationWithSecurityScope
includingResourceValuesForKeys: nil
relativeToURL: nil
error: &systemError];
But I get this error:
Error Domain=NSCocoaErrorDomain Code=256 "Could not open() the item"
UserInfo={NSURL=file:///Users/zach/Library/Containers/de.zach.ArtSaverApp/Data/Pictures/,
NSDebugDescription=Could not open() the item}!
All of this is happening under macOS 11.5.2 .
Any insights will be highly appreciated.
