cocoa - Xcode ARC (automatic reference counting), "release is unavailable"

Question

For my first time using Xcode I was following a tutorial online. I did everything as the tutorial showed me, but I am afraid that it's too outdated.

The error I encounter is:

[font_attributes release]; 

'release' is unavailable: not available in automatic reference counting mode

ARC forbids explicit message send of 'release'

My knowledge on Cocoa and Xcode is limited, but I still wish to expand my learning.

How may I fix the ARC issue?

Answer 1

The two options given by NJones are valid and effective ways of dealing with ARC incompatibility. However, you do have a third option. Disabling ARC for specific files.

Giving the flags -fno-objc-arc to your non ARC compatible compile sources affectively marks them as such upon compilation.

You can find your compile sources under Targets → Your App → Build Phases → Compile Sources.
