ios - What consequence does XCode 4.5 not supporting armv6 devices have?

Question

I've been reading about how XCode 4.5 has dropped support for armv6 but have not found a definitive statement about what the consequence of this are in terms of what devices/OSs can be supported when building with XCode 4.5.

I'm targeting my app at 4.n, 5.n and 6.n devices, however on 4.n I'm getting a runtime crash with

dyld: lazy symbol binding failed: Symbol not found: _objc_retainAutoreleasedReturnValue

Might this be related to XCode 4.5 no longer supporting armv6?

Answer 1

Xcode 4.5 と armv6 のサポートがないということは、iOS 4.3 以降しかサポートできないことを意味します。これは、アプリが元の iPhone または iPhone 3G で動作しないことを意味します。第 1 世代または第 2 世代の iPod touch では動作しません。
