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

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 projectplatform :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  endend

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

# Uncomment the next line to define a global platform for your projectplatform :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  endend

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.

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

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