Make -[NSData hexString] a public API

Originator:nicolas.bouilleaud
Number:rdar://19324941 Date Originated:2014-12-22
Status:Open Resolved:
Product:iOS SDK Product Version:8.2
Classification:Feature Reproducible:Always
 
Summary:
There’s no Apple-provided NSData-to-hexadecimal conversion API, and developers have been writing their own. In fact, even Apple engineers have rewritten it a dozen times.

Steps to Reproduce:
Search the docs for “-[NSData hexString]”

Expected Results:
Find such a method.

Actual Results:
Nothing :(

Version:
iOS 8.2b2

Notes:
Ideally, “hexString”, “ “lowercaseHexStringWithoutSpaces” and “ uppercaseHexStringWithoutSpaces” would be public.

See attached file for sample duplicates of this behaviour found in Apple-provided frameworks: this isn’t just needed by third-party devs, but also by Apple developers.

Configuration:
iOS Simulator 8.2
