Unable to find a target named `<Workspace Name>` in project `Xtreme.xcodeproj`

i'm working on swift 3 project with xcode 10.1, i have a requirement to install few pods (firebase/crashlytics), however when i trigger the pod install it seems to return the following error message. the previous used the same pod file and the project is running perfectly. the only issue is with installing new pods. anyone can help?

Get-R-Done -: Workspace name Xtreme -: Project name

Pod File

# Uncomment the next line to define a global platform for your project
 platform :ios, '9.0'

target 'Get-R-Done' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!
   pod 'SwiftyJSON', '~> 3.1'
   pod 'RealmSwift', '~> 2.1'
   pod 'ALCameraViewController'
   pod 'ReachabilitySwift', '~> 3'
   pod 'ILPDFKit', '~> 1.0'
   pod 'Fabric'
   pod 'Crashlytics'
   pod 'ActiveLabel', '~> 0.7'
   # Add the pod for Firebase Crashlytics
  pod 'Firebase/Crashlytics'

# Recommended: Add the Firebase pod for Google Analytics
  pod 'Firebase/Analytics'  


  # Pods for Get-R-Done

  target 'Get-R-DoneTests' do
    inherit! :search_paths
    # Pods for testing
  end

  target 'Get-R-DoneUITests' do
    inherit! :search_paths
    # Pods for testing
  end

end
