Xcode autocomplete crossed out?

Question

Having trouble finding an explanation in the docs, would someone be kind enough to explain to me what the red crossed out coordinate means in the image below?

Answer 1

The crossed out options indicate deprecated methods, though I'm not sure how the compiler has decided what is deprecated given that it has no idea what class the object is. For example, coordinate is deprecated in MKReverseGeocoder as of iOS5, as is the whole class.
