I\'m thinking about upgrading my OS X
You can install Xcode 4 by temporary editing the System Version.
Done, You now have Xcode 4 on 10.9 :)
Good Luck!
I was also running the same problem when I updated to xcode 5 it removed older sdk. But I taken the copy of older SDK from another computer and the same you can download from following link.
http://www.4shared.com/zip/NlPgsxz6/iPhoneOS61sdk.html

There are 2 ways to work with.
1) Unzip and paste this folder to /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs & restart the xcode.
But this might again removed by Xcode if you update xcode.
2) Another way is Unzip and paste where you want and go to /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs and create a symbolic link here, so that the SDK will remain same even if you update the Xcode.
Another change I made, Build Setting > Architectures > standard (not 64) so list all the versions of Deployment Target
No need to download the zip if you only wanted to change the deployment target.
Here are some screenshots.
You can install Xcode4 and Xcode5 on the same Maverick system. Just download Xcode 4 from https://developer.apple.com/downloads/ and drag Xcode.app to Desktop, rename it to Xcode4.app and move it to /Applications.
Done!
Correct, change the Deployment Target and set it to 6.1, even im also working on OS X 10.9 but want to use simulator 6.1.3 with Xcode 5. Im little confused that OS X 10.9 is going to support Simulator 6.1.3 with Xcode 5 or not. I want to make Simulator 7.0 look like iphone frame when it runs but nothing happening ...
I deploy onto my 4th gen touch from Xcode 5 on ML - not Mavericks, but should be the same.
Note, though, that you won't be able to submit to the App Store from Xcode 5 until just before iOS 7 is released.
Note, though, that you want to install Mavericks onto a seperate partition!!! Don't make it the only OS on your machine until it is released.
