When using the newest API for iOS 10.1.1 in my application and XCode for ios 6 the build has an issue when running on ios 5.0 even though this is the lowest version to be supported via the release notes. I do not see the problem in 5.1+. On the crash reports it is erring on setting the Units property of the AGSMapServiceInfo class. This is happening within the framework and outside my control.
-[AGSMapServiceInfo setUnits:] (in MyApp) (AGSMapServiceInfo.m:53)
Any ideas people? This method should be fine.
