how can pass protocol parameter in swift? in objective-c this: id <currentusercontex> usercontex = [servicelocator locate:@protocol(currentusercontex)]; service locator: + (id)locate:(id)objecttype edit after qbyte answer tried using: servicelocator.locate(currentusercontex.self) but i'm getting 'currentusercontex.protocol' not confirm protocol 'anyobject' so tried: servicelocator.locate(currentusercontex.self as! anyobject) but get: could not cast value of type 'applicationname.currentusercontex.protocol' (0x7fec15e52348) 'swift.anyobject' (0x7fec15d3d4f8). i suggest use if currentusercontex name of protocol itself: servicelocator.locate(currentusercontex.self) if currentusercontex variable type protocol use: servicelocator.locate(currentusercontex) i hope solves problem
