iPhone's other languages list from CLDR?

[Don Osborn]

Greetings, Does anyone know if Apple relied on CLDR for its long list of 
"other languages" (~240 by my estimation) on iPhone6c(plus)? Apologies 
that this is off-topic (replies offline probably best).

The list of "other languages" - not the "iPhone languages" fully 
supported in iOS - is impressive, though looking at some of the 74 
African languages* included (by my count) it seems most are not 
supported beyond calendars. Charles Riley suggested offline that some 
aspects of the list make it appear that it lists what's on CLDR.  
However there are some languages one would expect to see that are not 
there (Hausa, Amharic, among others).

Really interested to know more about Apple's thinking and methods on 
this. TIA for any info or leads.

Best wishes to all for the New Year 2016.
