время выполнения вывода objc[69590] при использовании CocoaPods с 2 проектами

Я создал 2 проекта xcode "mylib" и "myapp"

• тип проекта mylib - "iOS - > Cocoa Touch Framework "
• и тип проекта myapp - " iOS - > Application - > Single View Application".

Оба проекта зависят от" AFNetworking", поэтому я написал Подфайл ниже.

workspace 'myapp'

platform :ios,'7.0'
xcodeproj 'myapp/myapp.xcodeproj'

target :myapp do
    xcodeproj 'myapp/myapp.xcodeproj'
    pod 'AFNetworking', '~> 2.5.4'
end

target :mylib do
    xcodeproj 'mylib/mylib.xcodeproj'
    pod 'AFNetworking', '~> 2.5.4'
end

После запуска "pod install", я получил https://github.com/everettjf/cocoapods_two_projects_obj69272 , и строить без ошибки.

Но когда я запускаю "симулятор iOS", в окне консоли появляется много предупреждающих сообщений.
