ld: framework not found after pod install

问题

I added Firebase libraries to my project, and then I got this error. When I compile it, Xcode can't find some directories. However, they are in the Pods directory.

Here is the error log:

ld: warning: directory not found for option '-F/Users/Erumaru/Library/Developer/Xcode/DerivedData/ToDoTogether-gkzytezmbbgkikgoxjpptxgrixil/Build/Products/Debug-iphonesimulator/GTMSessionFetcher'
ld: warning: directory not found for option '-F/Users/Erumaru/Library/Developer/Xcode/DerivedData/ToDoTogether-gkzytezmbbgkikgoxjpptxgrixil/Build/Products/Debug-iphonesimulator/GoogleToolboxForMac'
ld: framework not found GTMSessionFetcher
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Here is my Podfile:

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

target 'ToDoTogether' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!
  platform :ios, '10.0'
    pod 'Firebase'
    pod 'Firebase/AdMob'  
    pod 'Firebase/Auth'
    pod 'Firebase/Crash'
    pod 'Firebase/Database'
    pod 'Firebase/Analytics'
    pod 'Firebase/Messaging'
    pod 'Firebase/RemoteConfig'
    pod 'Firebase/Storage'

  # Pods for ToDoTogether

end

Make sure you are opening the workspace file and not the project file. I was receiving the same error and realized I was using the project not the workspace.

I was facing same issue and I tried multiple things but still it was not working. I tried below.

Using XCworkspace file
Cleaned the project, restarted XCode, Mac
Turned bitcode to No
Deleted the search path for Framework, Library

Finally the thing that worked is, deleting pod file and re-creating pod file. It worked as magic!

P.S.: This is very generic error and so same solution may not work for all.

Go To Project Target > Build Settings:

Look for Search Paths > Framework Search Paths, delete all paths which you have been warned; then in Library Search Paths, delete all paths which you have been warned.
