Kakao navi 오류

iOS
#1

카카오 네비 길찾기 IOS에서 실행하려고 합니다.

info 에는 kakaonavi-sdk 추가하였고
예제처럼

let destination = NaviLocation(name: “des”, x: “321286”, y: “533707”)

        guard let navigetUrl = NaviApi.shared.navigateUrl(destination: destination)else {
            return
        }
                
        if UIApplication.shared.canOpenURL(navigetUrl){
            UIApplication.shared.open(navigetUrl,options: [:],completionHandler: nil)
        }else{
            UIApplication.shared.open(NaviApi.webNaviInstallUrl,options: [:],completionHandler: nil)
        }

하였으나 다음과 같은 에러가 나옵니다 무슨이유일까요

KakaoSDKNavi/NaviApi.swift:83: Fatal error: ‘try!’ expression unexpectedly raised an error: KakaoSDKCommon.SdkError.ClientFailed(reason: KakaoSDKCommon.ClientFailureReason.MustInitAppKey, errorMessage: Optional(“initSDK(appKey:) must be initialized.”))

#2

에러 그대로 “initSDK(appKey:) must be initialized.”)) 앱키 초기화를 안했다는 의미 같은데요.

앱키 초기화는 어떻게 하셨나요?
