Cocoapods: Resource file is added to bundle and copied in build phase causing duplicates

[mozeryansky]

In my podspec I have:

...
s.test_spec 'Tests' do |test_spec|
    test_spec.source_files = 'Tests/Sources/**/*'
    test_spec.resources = 'Tests/Resources/**/*'
end
... 

This causes the image I have in the Resources folder to be added to the 'Copy Bundle Resources' build phase, and CocoaPods adds it to the '[CP] Copy Pods Resources' phase. When building this duplicates the file.

Xcode produces this warning:
Showing All Messages :-1: ignoring duplicated output file: '/Users/michael/Library/Developer/Xcode/DerivedData/MyWorkspace-aeopwxywrxoflbeustfgkzsnmojk/Build/Products/Debug-iphonesimulator/MyTarget.xctest/background.jpg' (in target 'MyTarget')

Can you please upload a sample app?

[mozeryansky]

From building the sample project I've narrowed down the issue. It only happens when I have a custom scheme which builds the test target and the app in the same build. In the attached project there is a scheme called "All" which generates the issue.

I’m getting this too, but when I run pod lib lint for a library that has a test spec—I’m assuming the created project has the same problem as @mozeryansky’s sample app.

[mozeryansky]

@dnkoutso I attached a sample a while back, should that tag be removed?

[dnkoutso]

done. Most likely a legitimate issue.

[tinder-hemanthprasad]

@dnkoutso Do you happen to know a workaround for the warnings?

[mozeryansky]

@tinder-hemanthprasad I don't remember exactly, but I attempted to remove the warning by using a resource bundle instead and getting that specific bundle. Or you can just rename one of the assets.

In your podspec, something like:

-    test_spec.resources = 'Tests/Resources/**/*'
+    test_spec.resource_bundles = { 'Tests' => 'Tests/Resources/**/*' }

In code:

-        let bundle = Bundle(for: type(of: self))
+        let testsBundleURL = Bundle(for: type(of: self)).url(forResource: "Tests", withExtension: "bundle")!
+        let bundle = Bundle(url: testsBundleURL)!

[tinder-hemanthprasad]

@mozeryansky Moving Resources to a bundle caused the following warning.

Podspec,
test_spec.resource_bundles = { 'Fixtures' => 'Tests/Resources/*' }

Warning:

ignoring duplicated output file: '/Users/<******>/Fixtures.bundle' (in target 'Development-Pod-Unit-Tests')

[tinder-hemanthprasad]

I did this as workaround,

development_pod_unit_test_targets = installer.pods_project.targets.select {|t| t.name.include? "Unit-Tests"  }

def remove_copy_pod_resources_phase(targets)
    targets.each { |t| t.resources_build_phase.files.clear }
end

Resources are being copied in both the Copy Bundle Resources and Copy Pods Resources Phases.
