iOS dev on older Mac?

[prothero at earthednet.org]

Folks:
I have a Mac that is old enough so that the latest version of OSX it can run is 10.7. The latest version of Xcode (5.1) won't run on this OS. Will it be possible, or practical to make iOS apps using an older version of Xcode, or will the support tools, require the latest Xcode too? 

I'm asking this in order to decide whether I'm going to have to get a new computer if I want to do iOS and App development that requires Xcode.

Tnx,
Bill
