Question

How do I bail out of creating an object with ARC?

I’m looking for the ARC equivalent of this (from memory):

- (id)init
{
     if (( self = [super init] )) {
         if (!condition) {
             [self release];
             self = nil;
             return self;
         }
     }
     return self;
 }

Just get rid of the call to release and you’ll be fine. Since you nil self, there will be no more references to the old self so it will be deallocated.

- (id)init;
{
     if ((self = [super init])) {
         if (!condition) {
             return nil;
         }
     }
     return self;
 }
