[Error] 라이브러리 추가 시 Pods written in Swift can only be integrated as frameworks...

Error 내용:

Pods written in Swift can only be integrated as frameworks; add `use_frameworks!` to your Podfile or target to opt into using it. The Swift Pod being used is: ToastSwift

Error 수정:

# Uncomment the next line to define a global platform for your project

platform :ios, '10.0'

pod 'ToastSwift'

target 'iPhone_Test' do

  # Uncomment the next line if you're using Swift or would like to use dynamic frameworks

  # use_frameworks!

  # Pods for iPhone_Test

  target 'iPhone_TestTests' do

    inherit! :search_paths

    # Pods for testing

  end

  target 'iPhone_TestUITests' do

    inherit! :search_paths

    # Pods for testing

  end

use_frameworks!

end

Podfile의 맨 끝에 use_frameworks!를 추가해준다.
