ios - Is it safe to upgrade XCode 4.6.3 to Xcode 7? -


i have developed universal app works on both ipad running ios 9.3.5 & iphone running ios 6.1.4, using 2 different storyboards.

i realise need upgrade in order able distribute app on app store.

can run xcode 7 on os x lion? and, more importantly, objective-c code still work in xcode 7?

the code using basic. using uinavigationcontroller present data sqlite database. not using animation, location services or camera based classes. @ moment, have set deployment target 6.1. using 2 third party frameworks: ssziparchive & reachability

can give me reassurance, before assign month's worth of work scrap heap?

it hard tell, since means jumping 3 versions (!) ahead.
anyway, wholeheartedly recommend set git in project, make sure can revert if goes wrong.
btw- recommend updating xcode 8, latest version of xcode.
