Generic Protocol

Using Swift
1

I have a class, which uses a specific Protocol in several places. Like:

let connection.remoteObjectInterface = NSXPCInterface(with: MySpecialProtocol.self)

or:

let aProxy = connection.remoteObjectProxy as? MySpecialProtocol
...
private var currentProxy: MySpecialProtocol?

I would like to use this class also in other programs - with obviously some other Protocol.

I tried:

final class TestHandler  
{
	let SomeProtocol: Protocol
		
	init(protocol someProtocol: Protocol)
	{
		SomeProtocol = someProtocol
	}

	func test() -> Any  
	{		
		let connection = NSXPCConnection(serviceName: "machServiceName" )
		connection.remoteObjectInterface = NSXPCInterface(with: SomeProtocol.self)
		let aProxy = connectionToService.remoteObjectProxy
		
		//	Error: Cannot find type 'SomeProtocol' in scope
		let bProxy = connectionToService.remoteObjectProxy as? SomeProtocol

		return aProxy
	}
}

Any idea how to fix this? Also the function test() should return not "Any" but "SomeProtocol".
Maybe make the class generic about the protocol? But how?

Gerriet.

Did you mean to write?

final class TestHandler  {
	let someProtocol: SomeProtocol
		
	init (protocol: SomeProtocol) {
		someProtocol = protocol
	}
