Hi! Could you post a screenshot (or just a text list) of what shows up in the list in the "Target Dependencies" build phases for your ***App?

[dalu93]

Oh I noticed that the Target Dependencies field was empty. Adding the two extensions target fixed the issue. Thanks

[benasher44]

Awesome! Glad you got it fixed, and we appreciate you posting the solution!

BTW, if you want to make your Podfile a bit simpler, you could do:

[...]

abstract_target "App Pods" do
    target '***App'
    target '***Keyboard'
    target '***iMessageApp'

    pod 'Argo'
    pod 'Curry'
    pod 'Alamofire', '~> 4.0'
    
    abstract_target 'Test Pods' do
        inherit! :search_paths
        target '***Tests'
        target '***UITests'
        pod 'Quick'
        pod 'Nimble'
    end
end

[...]

HI @orta, thanks for the tip.
In this case, how to add a pod to the main app target only? I know this syntax results more concise, but for any customization I have to extract the target from the abstract one. Probably I'll prefer to stay with the old and not-pretty Podfile version. Just for my personal curiosity, will a solution like the one below work?

abstract_target "Generic Pods" do
    target '***Keyboard'
    target '***iMessageApp'
    
    pod 'Argo'
    pod 'Curry'
    pod 'Alamofire', '~> 4.0'
    pod 'AlamofireImage', '~> 3.1'
    
    abstract_target 'Main App Pods' do
        inherit! :search_paths
        target '***App'
        pod 'FBSDKLoginKit'
        pod 'FBSDKCoreKit'
        pod 'FBSDKShareKit'
    end
    
    abstract_target 'Test Pods' do
        inherit! :search_paths
        target '***Tests'
        target '***UITests'
        pod 'Quick'
        pod 'Nimble'
    end
end

Hrm, I think if you remove the inherit! :search_paths from Main App Pods then it should be 👍

[dalu93]

After using the new Podfile version, I got an error

framework not found Pods_***_iMessageApp

while archiving (debug was fine).
Under linked libraries settings, each target is linked to Pods_TARGETNAME.framework and the Pods_Generic_Pods_targetname.framework too. Is it right?

The Podfile I'm using is exactly the same I posted before, without the inherit! :search_paths line as @orta said

PS: the pod install operation removed also all my schemes

[dalu93]

Seems like pod deintegrate and pod install fixed it. As I said, the target was still linked to the old .framework

[dalu93]

Again me, just FYI, after user that Podfile, the test targets weren't compiling. Of course I forgot to move the test abstract target inside the Main App abstract target.

error is
Unable to find host target(s) for ReadLaterExtension. Please add the host targets for the embedded targets to the Podfile.
Certain kinds of targets require a host target. A host target is a "parent" target which embeds a "child" target. These are example types of targets that need a host target:

• Framework
• App Extension
• Watch OS 1 Extension
• Messages Extension (except when used with a Messages Application)

pls help me to solve this

thank you

In order to disable building/running the NSExtension you build, you should:

1. Click the project file in the project navigator
2. Click the containing app target (the one you DO want to run)
3. Click Build Phases tab
4. Open Target Dependencies
5. Remove the extension (the one you DON'T want to run)
6. To bring it back, simply click the + sign in the same place and
   re-add it.

In my case working sucessfully

5. Remove the extension (the one you DON'T want to run)

In my case working sucessfully

In my case I just add extension that was in error string. That fix issue. Thanks.
