5.1.1

I'm seeing the same issue. I'm building with a target of 5.1.1, and there are no references to iOS 5.1 anywhere in the project. Yet I get this warning on every .o file being linked. I have not found a solution yet.

According to Apple one must build kernel extensions against the SDK for the lowest OS version they are to support. See WWDC 2013 session 707 What's New in Kext Development. In your case this would be the 10.8 SDK. You were just lucky that the kext built with Xcode 5.1.1 and the 10.9 SDK worked on 10.8. The trick with setting the deployment target to a version lower than the SDK only works for userspace code. This makes things difficult for kernel developers that need to support older OS version since we are forced to use old Xcode versions, on old OS's, on old hardware, for developement.

Well, considering Xcode 5.1.1 is still allowed, it seems that 7.x will not be mandated for some time. Beyond 2016 I'd guess.Why do you ask?

OK so i have been looking at this again,and i have soem more info.I have recently moved my Dev Box to 10.10, hopwever i am still using XCode 5.1.1 and linking against the OSX 10.9 Libraries,well specifying OSX 10.9 as the Base SDK in my project settings.But now i am getting an error message when i make the [assetWriterAudioInput markAsFinished]; callcalling [assetWriterVideoInput markAsFinished] appears to complete ok, but calling, gives me the following error in the output.. figSampleBufferCheckDataSize signalled err=-12731 (kFigSampleBufferError_RequiredParameterMissing) (bbuf vs. sbuf data size mismatch) at /SourceCache/CoreMedia_frameworks/CoreMedia-1562.235/Sources/Core/FigSampleBuffer/FigSampleBuffer.c line 1286Additionlly When i call: [assetWriter endSessionAtSourceTime:endTime];i get the following erros in the console[16:20:28.901] <<<< FAC >>>> RunConverter: Fatal: AudioConverterFillComplexBuffer returned 1768846202[16:20:28.901] <<<< MediaProcessor >&g

I did call apple and told them that in itunes am getting same error need xcode 5.1.1 or later and I have 7 ????? I upload the app with xcode but still not showing in itunes...I call back and you have to be lucky to get someone that knows what a **** they doing, I got a guy the other day and help me to upload but today when I call this woman didn't know a thing.....

Considering changes have to roll out to multiple web servers in multiple countries it makes perfect sense that there is a delay between a new toolset and support for that toolset in iTunesConnect. And it isn't just the sites that need updating. The backing databases also have to be updated as do internal policies and sometimes even guidelines.also consider Xcode 5.1.1 was still being displayed as the minimum to submit apps last time I looked.

Try Xcode 5.1.1, I think.
