Ошибка Apple Mach-O Linker. Не удалось выполнить команду Linker с кодом выхода 1

Question

Мое приложение отлично работало последние пару дней, но внезапно я получаю эту ошибку.

Я уже пробовал эти вещи:

• Restart Xcode & макинтош
• Чистые проекты
• Clean Производные папки Data

Здесь ошибка:

А вот еще одно предупреждение

Answer 1

Удаление Checkbox для тест-мишеней исправили проблему.

Answer 2

Если вы столкнулись с этой проблемой с Cocoapods во время модульного тестирования, вы можете просто добавить стручки к цели тестирования и запуска pod update в терминале. А вот мой пример, и он решает проблему:

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

    # Pods for YourProject 
    pod 'RAMAnimatedTabBarController', '~> 2.0.13' 
    pod 'XLPagerTabStrip', '~> 7.0' 
    pod 'ZFRippleButton' 
    pod 'Alamofire', '~> 4.4' 
    pod 'SWXMLHash', '~> 4.0.0' 
    pod 'SQLite.swift', '~> 0.11.3' 
    pod 'DZNEmptyDataSet' 
    pod 'PKHUD', '~> 4.0' 

    target 'YourProjectTests' do 
     # inherit! :search_paths 
     # Pods for testing 
     pod 'RAMAnimatedTabBarController', '~> 2.0.13' 
     pod 'XLPagerTabStrip', '~> 7.0' 
     pod 'ZFRippleButton' 
     pod 'Alamofire', '~> 4.4' 
     pod 'SWXMLHash', '~> 4.0.0' 
     pod 'SQLite.swift', '~> 0.11.3' 
     pod 'DZNEmptyDataSet' 
     pod 'PKHUD', '~> 4.0' 
    end 

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

end 

После добавления стручков выше, запустите pod update.
