This applies to the iOS5-only development branch, don't know if the master branch has the same issue. MR fails to compile unless the MR_SHORTHAND feature is enabled (i.e., the macro is defined). Without it, the following errors ensue:
Automatic Reference Counting Issue - No known class method for selector 'findFirstByAttribute:withValue:inContext:'
Automatic Reference Counting Issue - No known class method for selector 'createInContext:'
Has this been address in a newer release of MagicalRecord?
Given the age of this issue, and the volume of issues we have to work through, I've decided to close this.
If the issue described is still relevant, please feel free to re-open and one of @magicalpanda/team-magicalrecord will take another look. Thanks!
