Recebi esse aviso quando executei o aplicativo no meu iPhone.

warning: Unable to read symbols for /Users/illep/Library/Developer/Xcode/iOS DeviceSupport/4.3.3 (8J3)/Symbols/System/Library/Internet Plug-Ins/YouTubePlugIn.webplugin/YouTubePlugIn (file not found).

warning: No copy of YouTubePlugIn.webplugin/YouTubePlugIn found locally, reading from memory on remote device.  This may slow down the debug session.

O que isso significa ? e como posso me livrar dele?
