SpotifyのAPIを使いたくてimportしたはずのheaderがnot foundになる

###前提・実現したいこと
Swift4とxcode9.0でSpotifyのAPIを使ってみるアプリ（"SpotifyStudy"）を開発しています。

このアプリが起動するとSpotifyのログイン画面が立ち上がり、自分のアカウントでログインすると楽曲が再生されるという仕組みです。

Spotifyの公式チュートリアルがObjective-C用だったのでSwiftで使うためにBridge Headerを自分なりに調べて書いていたのですが以下のような2つのエラーが解決できません。

###発生している問題・エラーメッセージ

/Users/[私のユーザネーム]/Desktop/SpotifyStudy/SpotifyStudy/SpotifyStudy/SpotifyStudy-Bridging-Header.h:13:9: error: 'SpotifyAuthentication/SpotifyAuthentication.h' file not found
#import <SpotifyAuthentication/SpotifyAuthentication.h>

<unknown>:0: error: failed to emit precompiled header '/Users/[私のユーザネーム]/Library/Developer/Xcode/DerivedData/SpotifyStudy-aasqdpuzvhmgwneqbieddvtsoiam/Build/Intermediates.noindex/PrecompiledHeaders/SpotifyStudy-Bridging-Header-swift_RTWEOMNR105G-clang_149BTWH3ZJQG5.pch' for bridging header '/Users/[私のユーザネーム]/Desktop/SpotifyStudy/SpotifyStudy/SpotifyStudy/SpotifyStudy-Bridging-Header.h'
