Some people often complain loudly and passionately that Delphi needs a garbage collector and that reference counting is not good enough, but if I read this correctly, in the new OS X release – ‘Lion’ – Apple seem to think that reference counting is an improvement over more sophisticated garbage collection techniques.<\/p>\n

From the details discussed in page 10 of a a very, VERY detailed review of Lion<\/a>, it seems on the face of it that Apple’s brand new “ARC” (A<\/strong>utomatic R<\/strong>eference C<\/strong>ounting) seems to work exactly like Delphi’s own automatic reference counting of interfaces (and strings and dynamic arrays…) !! \u00a0Even if not entirely identical, the similarities are certainly close enough to be worthy of a raised eyebrow or two, and a little puff of pride at Embarcadero (or among former Borland’ers, where-ever they may now be).<\/p>\n

Where Delphi leads, it appears Apple sometimes follows…<\/p>\n

Of this, this perhaps should not be all that surprising … some people may not be aware that Delphi owes a debt of gratitude to Apple for ObjectPascal<\/a> in the first place.<\/p>\n","protected":false},"excerpt":{"rendered":"
