Taking a cue from the declaration of NSXPCInterface itself, I can fix that problem like this (using a protocol that exists for me, just for this test): let b = NSXPCInterface( `protocol`: NSTableViewDelegate ) After that, the compiler gives another error, and offers to fix it to: let b = NSXPCInterface( `protocol`: NSTableViewDelegate.self ) which compiled without error. Then I tried declaring a protocol called ‘Xpc_CommonProtocol’ and using it instead: protocol Xpc_CommonProtocol {} let b = NSXPCInterface( `protocol`: Xpc_CommonProtocol.self ) and that fails with a hard-to-interpret error about type “Protocol”. Fiddling around, I changed it to: @objc protocol Xpc_CommonProtocol {} let b = NSXPCInterface( `protocol`: Xpc_CommonProtocol.self ) and it compiled. I guess it makes sense that it has to be an Obj-C protocol, but getting there isn’t at all obvious. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
