Issue with Cocoapod, macOS High Sierra and Firebase dependencies

问题

Here is my issue, I recently updated to macOS High Sierra and Xcode 9.1. I also installed cocoa pods. Then, I have a project, an IOS app which uses Firebase realtime database and Firebase storage.

So, I follow the guide provided by Firebase step by step but I always end with this issue when I try to build my project :

GTMSessionFetcher.framework: No such file or directory

or

GoogleToolboxForMac.framework : No such file or directory

I already read several similar posts on stackOverflow and I try different solutions provided but nothing works... I tried :

• Clean the project
• Open .xworkspace
• Uninstall/Reinstall pods
• Delete Derived Data
• Close/Open workspace
• Restart Mac

Here is my pod file :

# Uncomment the next line to define a global platform for your project
platform :ios, '11.1'

target 'Jack\'n\'Ferdi' do
 use_frameworks!
 pod 'Firebase/Core'
 pod 'Firebase/Database'
 pod 'Firebase/Storage'
end

Pods are installed without errors when I launch pod install into the command line. I also try pod update. I am kind of desperate...

Update When I create a new project from scratch and add those pods, it works perfectly ! The initial project is not from scratch. I got it from Github.
