Solution 1

Go here in your build settings...

And then highlight the "Always embed..." row and hit delete. This will change it to use the inherited property.

Even after you make this change it will remain there but it will probably change from bold to normal text. If that change happens then it is inherited.

Normal text = inherited.

Bold text = overridden.

Solution 2

I was able to fix this problem by doing the following (step by step):

1. Go to Build Settings
2. At the top select All and Combined
3. Under Build Options you should see Always Embed Swift Standard Libraries and it is bold.
4. Click on it and click delete (<-). It should now be unbolded. (Normal text = inherit)
5. Pod install and the error/errors should go away!

Solution 3

1. Go to Build Settings
2. At the top select All and Combined
3. Under Build Options search "Always Embed Swift Standard Libraries"
4. Update its value with $(inherited)
5. Now install pod and all the error should go.

Solution 4

The accepted solution works, but now you have to make sure all of your teammates are performing it each pod install.

And we all know they won't.

You could make CococaPods do it automatically, by adding this to the bottom of your Podfile:

post_install do |installer_representation|
    installer_representation.pods_project.targets.each do |target|
        target.build_configurations.each do |config|
            if config.name == 'MyPOD' 
                config.build_settings['ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES'] = 'Yes'
            end
        end
    end
end

Solution 5

I suggest to set all pods after install as suggested in the message:

post_install do |installer_representation|
    installer_representation.pods_project.targets.each do |target|
        target.build_configurations.each do |config|
            config.build_settings['ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES'] = '$(inherited)'
        end
    end
end

I hit delete and nothing changed. could you be more specific , please ? I'm very new to iOS devlopment.

[Fogmeister]

It will remain there but it will prob change from bold to normal text. If that change happens then it is inherited. Normal text = inherited. Bold text = overridden.

[MEH]

Good , then should I do it for every project I'll make or there's a global configuration for Cocoapods ?

@Fogmeister for better visualisation of inheritance he also can select Levels option. It's way more visual than checking boldness of a text.

[Rob Norback]

This was super helpful, it was silly hard to find that setting.

[ArgaPK]

Could you please tell me, are these errors or warnings? i am new , although the pods installed completely: "[!] The LearningTests [Debug] target overrides the ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES build setting defined in Pods/Target Support Files/Pods-LearningTests/Pods-LearningTests.debug.xcconfig'. This can lead to problems with the CocoaPods installation - Use the $(inherited)` flag, or - Remove the build settings from the target." , is this a warning or error? is the pods install successfully?

[Ryan Brodie]

@ArgaPK Yes exactly, follow their instructions and they'll go away

[responser]

Simple and effective!

[Manesh]

worked for me, for all those still getting errors, make sure to do this to the Targets OS and UITests also!

Can't delete on Xcode 11. Well, hitting on Delete just make it not bold, but doesn't actually delete the property.

[Zorayr]

Been a while, but pretty sure I was just hitting on the Delete button.

[ergunkocak]

It worked for me at the time. Cocoapods evolved since then ;)

2022 here and it still works. Thanks
