Could I use iOS SDK 5.1 or earlier in Xcode 4.5.1?

It's there....

Set Base SDK to Latest/iOS 6, then set iOD Deployment Target to iOS 5.

Nope. Only iOS 6 is available.

Can the 5.1 SDK be added somehow?

What part of KT's answer don't you understand.

IT'S THERE! YOU DON'T NEED TO DO ANYTHING OTHER THAN WHAT KT SAID!

Easy please.

It really is "not there" - would love advice on getting it installed.

That doesn't mean that other iOS SDKs can be installed. It's just showing which SDK is installed.

Thanks - yes - and therefore the question: How?!

(Tried checking for additional downloads in xcode (version 4.5.1), and the developer.apple.com site - but no luck.)

You can't because you don't need it and it's not possible to "load" it.

thanks for your attention Michael,

So, if I understand you correctly:

I can build and deploy iOS apps to be run on an iPad with iOS 5.1 using the iOS 6 SDK that came with Xcode 4.5.1 ?

Correct.

That's exactly what KT said in his reply.

ok - I find that hard to believe, but... I'll try.

Thanks!

Did you follow every bit of KT's instructions? Your screenshot in a previous post shows you did the first half, what about the second?

Set Base SDK to Latest/iOS 6, then set iOD Deployment Target to iOS 5.

For future reference and other viewers: this works!

Thanks for helping!
