Rand-Emonium Software has released version 2.6 of the 8-bit Apple // build pipeline for Xcode. The build pipeline still supports AppleSoft BASIC, Merlin assembly and cc65 based projects. Version 2.6 introduces support for cc65 v2.17 along side the existing support for v2.13.3. Easily installed MacOS packages of both versions of cc65 are available.
Credit to Kris Kennaway for providing patches for cc65 v2.17 to make this update possible.
