Can ARC be used in iOS 4.3?

mikezang · Jan 15, 2013, 06:56 PM

My app is used by some iOS 4 users, I am going to use some open source to improve my app, but some of them are in ARC, I can't test it because Xcode 4.3 without iOS 4.3 simulator , does anyone tell me if I can use those open source? What should I do?

ARC is supported in Xcode 4.2 for Mac OS X v10.6 and v10.7 (64-bit applications) and for iOS 4 and iOS 5. Weak references are not supported in Mac OS X v10.6 and iOS 4.

Source: Apple Docs

From this you can gather arc can work and target iOS 4.3 as long as it does not use any weak references. Therefore you should be able to use XCode 4.3/ Or the latest 4.5 to compile and target iOS 4.3.
