Type 'WatchManager' does not conform to protocol 'WCSessionDelegate'

Question

I try use WatchManager.swift in exists project.

import Foundation
import WatchConnectivity

class WatchManager: NSObject, WCSessionDelegate {


    func session(_ session: WCSession, activationDidCompleteWith activationState: WCSessionActivationState, error: Error?) {

    }

    func sessionDidBecomeInactive(_ session: WCSession) {

    }

    func sessionDidDeactivate(_ session: WCSession) {

    }
}

but I have trouble on build my project

Swift Compiler Error Group - Type 'WatchManager' does not conform to protocol 'WCSessionDelegate'

Also in issue navigator i see error

Candidate has non-matching type '(WCSession, WCSessionActivationState, Error?) -> ()'

I already tried:

remove derived data
clean project
clean builds folder
reload project from git
copy file from another project
create new file and rename it
build project on another mac

but i get this error everytime

BUT! If I will create new project and add watchOS target and create new file with this code - project will build successfully.

Why? How i can try to add WCSessionDelegate in my exists project?

I use Xcode9.2, swift4.0

Oh... Thank @Sameer for answer

WCSessionDelegate has required method

public func session(_ session: WCSession, activationDidCompleteWith activationState: WCSessionActivationState, error: Error?)

but my project there is my custom class with name Error

that's why the compiler produced an error that does not conform to protocol

Type 'WatchManager' does not conform to protocol 'WCSessionDelegate'
