hi! I have an iPhone 4 on iOS 5.0.1 and an iMac with OSX 10.9.2 I have recently been messing with Xcode and am wanting to put apps that I make on my phone. Currently Xcode 5 only lets you test for iOS6 and 7. I am wondering if it is worth upgrading my iPhone 4 to iOS 6 to be able to mess around with developing my own apps or would iOS6 be too slow to even bother with on the 4. Thanks in advance for any suggestions and opinions.
