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

Verify if all your targets are using the same iOS version in: Build Settings -> iOS Deployment Target

To install all dependencies, I added these lines to your Podfile:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    if ['PagingMenuController', 'TCPickerView'].include? target.name
      target.build_configurations.each do |config|
        config.build_settings['SWIFT_VERSION'] = '3.0'
      end
    end
  end
end

Then I removed use_frameworks! (see this link for more details) from your Podfile, run pod update and after that I was able to run tests.

For more details see this answer.

If you are using swift 3 or swift 4 and want to add UITest to your Project than don't forget following steps :

1. Remove use_frameworks! from your pod file and update your pod file with pod versions of dependencies like below
2. Use post_install to specify your swift version .
3. Remove ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES Or set Them to No in both target app (myAPP & myAPUITests)
4. Then run following commands :

5. pod deintegrate , pod clean & pod install

   # Uncomment the next line to define a global platform for your project platform :ios, '9.0'

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

         # Pods for myAPP
           pod 'SwiftMessages', '4.1.4'
           pod 'IQKeyboardManager', '6.1.1'
           pod 'SwiftKeychainWrapper', '3.0.1'
           pod 'Tabman', '1.9.1'
           pod 'PagingMenuController', '2.2.0'
           pod 'Kingfisher', '4.8.0'
           pod 'Optik', '0.3.0'
           pod 'KRPullLoader', '1.1.3'
           pod 'AlamofireImage', '3.3.1'
           pod 'Firebase/Core'
           pod 'Firebase/Database'
           pod 'Firebase/Messaging'
           pod 'Firebase/Auth'
           pod 'Firebase/Storage'
           pod 'TCPickerView', '0.2.5'
           pod 'GoogleMaps', '2.7.0'
           pod 'GooglePlaces', '2.7.0'
           pod 'Whisper', '6.0.2'
           pod 'Fabric', '1.7.9'
           pod 'Crashlytics', '3.10.5'
           pod 'SwiftyJSON', '4.1.0'
           #pod 'Alamofire', '4.7.3'
         pod 'SwiftGridView', '0.6.5'
         target 'myAPPUITests' do
           inherit! :search_paths
           # Pods for testing
         end
       end
   

add following at the end of your pod file

post_install do |installer|
    print "Setting the default SWIFT_VERSION to 4.0\n"
    installer.pods_project.build_configurations.each do |config|
        config.build_settings['SWIFT_VERSION'] = '4.0'
    end

installer.pods_project.targets.each do |target|
    if [].include? "#{target}"
        print "Setting #{target}'s SWIFT_VERSION to 4.2\n"
        target.build_configurations.each do |config|
            config.build_settings['SWIFT_VERSION'] = '4.2'
        end
    else
        print "Setting #{target}'s SWIFT_VERSION to Undefined (Xcode will automatically resolve)\n"
        target.build_configurations.each do |config|
            config.build_settings.delete('SWIFT_VERSION')
            #config.build_settings['SWIFT_VERSION'] = '4.0'
        end
    end
end
end
