Dave, You want to apply the type annotation to the innermost pointer of theErrorPtr. My guess is you want something like this:
-(nullable LTWNodeInfo*) getNodeAtIndexPath:(nonnull NSIndexPath*) theIndexPath error:(NSError**_Nullable) theErrorPtr; this will allow you to do something like: NSError *err; LTWNodeInfo *nodeInfo = [self getNodeAtIndexPath:somePath error:&err]; whereas, annotating theErrorPtr like this: -(nullable LTWNodeInfo*) getNodeAtIndexPath:(nonnull NSIndexPath*) theIndexPath error:(NSError**_Nonnull) theErrorPtr; would give you a warning at the call site for the above example.
