The problem you’ve got is that unless the font has a feature that specifically allows you to change *any* colon (as opposed to a colon between two numerals), you aren’t going to be able to do it by turning on an OpenType feature. Even if you can, there doesn’t appear to be a standard feature code for this, so you’d be reliant on Apple not changing it in the future. What you *could* do instead is get Core Text (or Cocoa Text) to lay out a string e.g. "12:00”, then grab the glyph for the centred colon directly from that string and use it explicitly, e.g. by attaching a kCTGlyphInfoAttributeName attribute to your string with the value set to an appropriately constructed CTGlyphInfoRef.
