The bundle UITests couldn’t be loaded because it is damaged or missing necessary resources. Try reinstalling the bundle

Question

I can't run my test case due to this following errors :

• The bundle “UITests” couldn’t be loaded because it is damaged or missing necessary resources. Try reinstalling the bundle.
• Library not loaded: @rpath/Alamofire.framework/Alamofire.
• Reason: image not found

Try searching and solving since two days but couldn't get through this issue can someone please help.

Answer 1

I was able to reproduce this issue with the project generated by Xcode 10.1. I used Swift 4.2 and CocoaPods 1.10.0 as a dependency manager. I had the following Podfile:

# Uncomment the next line to define a global platform for your project
platform :ios, '10.0'

target 'MyApp' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!

  # Pods for MyApp
  pod 'Alamofire', '4.8.1'

  target 'MyAppTests' do
    inherit! :search_paths
    # Pods for testing
  end

  target 'MyAppUITests' do
    inherit! :search_paths
    # Pods for testing
  end

end

Then I removed use_frameworks!, see this link for more details:

# Uncomment the next line to define a global platform for your project
platform :ios, '10.0'

target 'MyApp' do

  # Pods for MyApp
  pod 'Alamofire', '4.8.1'    

  target 'MyAppTests' do
    inherit! :search_paths
    # Pods for testing
  end

  target 'MyAppUITests' do
    inherit! :search_paths
    # Pods for testing
  end

end

I also received some warnings like this:

[!] The `MyAppUITests [Debug]` target overrides the `ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES` build setting defined in `Pods/Target Support Files/Pods-MyApp-MyAppUITests/Pods-MyApp-MyAppUITests.debug.xcconfig'. This can lead to problems with the CocoaPods installation
    - Use the `$(inherited)` flag, or
    - Remove the build settings from the target.

That's why I removed this line from the MyAppUITests build settings:

After that run pod deintegrate && pod install and then the problem disappeared. Probably for projects with more dependencies (like here) you need to use another solution.

Answer 2

It's because your pods only apply to your Framework target and no the tests one. Add the tests target to your podfile.

Example :

target 'MyFramework' do
  use_frameworks!
  pod 'Alamofire', '~> 4.5'
end

target 'MyFrameworkTests' do
  use_frameworks!
  pod 'Alamofire', '~> 4.5'
end

Answer 3

In your tests target change inherit! :search_paths to inherit! :complete. See the documentation for what this does.

Answer 4

Check that the deployment target in your UITest target Build Settings is set to the same as the host application you are trying to test. In my case, I added the UITesting target later on, and it created it with a default of deployment target iOS 12. If you then try to run the UITest on iOS lower than 12, it gave me the error mentioned in the question.

Answer 5

In my case, I needed to separate the UI tests target with use_frameworks!.

Moving the UI tests target from nested structure to its own will not help, if you specified use_frameworks! globally somewhere in the top of the Podfile.

The Podfile with error (original):

platform :ios, '10.0'

inhibit_all_warnings!
use_frameworks!

target 'MyProject' do
  pod 'R.swift', '~> 5.0'
  pod 'Moya/RxSwift', '~> 12.0'
  # and other pods

  target 'MyProjectTests' do
    inherit! :search_paths

    pod 'iOSSnapshotTestCase', '~> 6.0'
  end

  target 'MyProjectUITests' do
    inherit! :search_paths
  end
end

The Podfile with error (first try to fix):

platform :ios, '10.0'

inhibit_all_warnings!
use_frameworks!

def shared_pods
  pod 'R.swift', '~> 5.0'
end

target 'MyProject' do
  shared_pods

  pod 'Moya/RxSwift', '~> 12.0'
  # and other pods

  target 'MyProjectTests' do
    inherit! :search_paths

    pod 'iOSSnapshotTestCase', '~> 6.0'
  end
end

target 'MyProjectUITests' do
  shared_pods
end

The final working Podfile:

platform :ios, '10.0'

inhibit_all_warnings!

def shared_pods
  pod 'R.swift', '~> 5.0'
end

target 'MyProject' do
  use_frameworks!

  shared_pods

  pod 'Moya/RxSwift', '~> 12.0'
  # and other pods

  target 'MyProjectTests' do
    inherit! :search_paths

    pod 'iOSSnapshotTestCase', '~> 6.0'
  end
end

target 'MyProjectUITests' do
  shared_pods
end
