Hi, I am trying to create a hard link on MacOS(Mac Catalyst App) between files using [self linkItemAtURL:fromURL toURL:toURL error:&error]; Source Path for MacOS - /var/folders/lf/dt_4nxd945jdry2241phx0_40000gn/T/net.appname.AppName/documents/... Destination Path for MacOS - /Users/username/Library/Group Containers/group.net.appname.AppName.shared/Message/Media/... Although the same code works fine on iOS, but getting following error on MacOS Error Domain=NSCocoaErrorDomain Code=513 couldn’t be linked because you don’t have permission to access, Operation not permitted Source Path for iOS - /Users/user/Library/Developer/CoreSimulator/Devices/B4054540-345F-4D90-A3C5-DA6E6469A3FC/data/Containers/Data/Application/B4AB7D70-491C-49E5-9A3F-27E66EC3423D/tmp/documents/... Destination Path for iOS - /Users/user/Library/Developer/CoreSimulator/Devices/B4054540-345F-4D90-A3C5-DA6E6469A3FC/data/Containers/Shared/AppGroup/842B248E-CCA6-4B5C-82BD-2858EADD3A90/Message/Media/... However, interestingly if I try to copy the file, it works perfectly fine on MacOS as well. I am unable to understand if it is the permission issue, it should not work with copy as well. Does anyone have any reason/solution to this behaviour?
