Ios 在iPad视网膜或真实设备上运行时出现Pod错误

这是我的Pod文件

platform :ios, '8.0'
target "Earcrush" do
pod 'PureLayout'
pod 'ECSlidingViewController'
pod 'KGModal'
pod 'AMPopTip'
pod 'WYPopoverController'
pod 'UITextView+Placeholder'
pod 'SVPullToRefresh'
pod 'XCDYouTubeKit'
pod 'youtube-ios-player-helper'
pod 'M13ProgressSuite'
pod 'PINRemoteImage'
pod 'BLKFlexibleHeightBar'
pod 'Firebase/Core'
pod 'Firebase/Database'
pod 'GoogleAPIClient'
pod 'GoogleAPIClient/YouTube'
pod 'GTMOAuth2'
end

当我在任何iPhone模拟器上运行我的项目时，它将成功运行
然而，当我尝试在iPadRetina（iOS8或iOS9）上运行时，我得到了下面的错误。我尝试过清理项目，重新打开Xcode，但没有成功

我的吊舱怎么了？任何帮助或建议都将不胜感激。
