There is only one way to solve this issue.

Quit Xcode.
Delete project's temp files located at ~/Library/Developer/Xcode/DerivedData
Delete ProjectName.xcworkspace
Delete Podfile.lock file and Pods folder
Run pod install.
Open the newly created ProjectName.xcworkspace file and build.

If I delete ProjectName.xcworkspace, does it delete the previous code there? – Cons Bulaquena Apr 16 '18 at 19:19
@ConsBulaquena Actually, you have to delete the `xcworkspace`, it doesn't include the code you wrote but is automatically generated by Pod, don't worry about it. – Dimitris Bouzikas Apr 17 '18 at 06:32

I am using Swift 4 and Xcode 9. All I have to do is selecting FirebaseCore Scheme.

On Xcode:

Product->Scheme->FirebaseCore.

If you don't have FirebaseCore go to Manage Schemes and select it. Then try again.

This may fix your problem:

Quit the Xcode. (Don't just close the Xcode window, right click and Quit it explicitly).
Go to ~/Library/Developer/Xcode/DerivedData and delete the project folder. (Simply delete all the folders).
Clean and Build the project.

If still error exist:

Do steps 1 and 2 and follow this steps:

Change scheme to Firebase and Build (Command + B).
Change back to your app scheme and Run again.

I opened the project with .xcodeproj and I installed Firebase with cocoapods. I got the same error. But I just close the project and open it with .xcworkspace.

The alert has gone. Firebase was the first library on my project. So I kept using .xcodeproj file.

Install FireBase properly via CocoaPods. Try the following steps

Step 1 - Close Xcode

Step 2 - Clear your derived data. You can find your derived data in here

~/Library/Developer/Xcode/DerivedData

Step 3 - Open your .xcworkspace

Step 4 - Clean your project (⌘+Shift+K)

Step 5 - Build your project (⌘+B)

Make sure your are opened .xcworkspace file

Tried the above suggestions, but they didn't work for me. What worked for me was to build to Generic iOS Device first and then run it on my physical device iPhone6.

I still couldn't run it on a simulator, however. What worked here was to change Build Active Architecture Only - Debug to NO, in the Pod Project Build Settings.

Hope this helps someone.

It happened to me because I installed the Firebase CocoaPods but I didn't reopen it through the <projectName>.xcworkspace file. So what I did to work was:

I quit Xcode
opened it by clicking the <projectName>.xcworkspace file of the project
then I could use "import Firebase" on my project.

I recently had this problem when using Xcode 12. I found that removing the Valid Architectures build setting (VALID_ARCHS) fixed it.

From the Xcode 12 release notes:

The Build Settings editor no longer includes the Valid Architectures build setting (VALID_ARCHS), and its use is discouraged. Instead, there is a new Excluded Architectures build setting (EXCLUDED_ARCHS). If a project includes VALID_ARCHS, the setting is displayed in the User-Defined section of the Build Settings editor.

Can you please try to take a look at my answer here

TL;DR make sure you are running cocoapods version 1.4.0 minimum. It fixes static framework imports.

You can do this by running sudo gem install cocoapods on your terminal and verify your version by typing pod --version

For me the issue was simple. I have a new m1 mac and it has trouble loading cocoa pods sometimes. Simply:

Click your pods project(blue pods)->
Click all & build settings ->
Excluded architectures ->
add "arm64" to both debug and release ->
set any SDK on left side ->
do this on your main project folder too ->
build it your good to go

This happened to me today, I just couldn't figure out why, because when I closed the file that night, everything was perfect. I opened my file using the recent projects menu and got this issue. Then I decided to check something, Xcode opened the wrong file. Instead of opening the workspace file with the pods, it opened the Xcode project.

Once I opened the workspace it was error free and all the pods were behaving. Im sure you guys are all more experienced than me, but I just wanted to throw that in there.

Nothing here worked for me, but then I figured out something that did work.

When I clicked on my project in Project Navigator in Xcode, and then selected Info I looked at the Configurations section and saw that there was only a Release configuration and no Debug configuration for my app.

In order to get Firebase to work, I went to Pods within the Project Navigator, and under the Configurations section I deleted the Debug configuration. Now it builds fine. Hopefully this will help someone else.

After 2 days of searching and trying every single step proposed in this post, eventually i could solve the problem. None of the above approaches solved my problem but this one:

There is a package of Firebase frameworks available to download from this link: https://firebase.google.com/download/ios?authuser=0
There is a Firebase.h header file in this package. I added this header file to my project resources.
Finally i added a line of code at the top of this file: ' #import "Firebase.h" '

Simply and Easily the error is gone!

None of above solutions worked for me. I found that the problem was I have three targets in Cocoapods file. And only my main one target has Firebase added. So that when I want to import Firebase to a file that is used in other targets, Xcode gives error and says Module 'Firebase' not found. This is my pods project file. One solution for me is adding Firebase pod to all targets. Or another solution is removing the file from other targets.

def common_pods
  pod 'XXX'
end

target 'myMainProject' do
  common_pods()
  pod 'Firebase/Core'
  pod 'Firebase/AdMob'
  pod 'Firebase/RemoteConfig'
  pod 'Firebase/Crashlytics'
  pod 'Firebase/Analytics'

I had a same issue with a Flutter project.

You should exclude arm64 for simulator architecture both from project and every pod target

Exclude arm64 from the project

Add this code to Pofile

post_install do |installer|
  installer.pods_project.targets.each do |target|
    # exclude arm64 for simulator architecture the pod target
    target.build_configurations.each do |config|
      config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"

I had the exact same issue

You could be reinstalling pods with your Xcode open Or your pods file won't allow and overwrite

With your workspace open, delete the "Pods" folder. Quit X-Code Open terminal in "Utilities" You'll find this in "Applications" Using cd ... go to your project folder reinstall pods using "pod install".

That should fix it.
