Q:

Wikitude - @synthesize of 'weak' property is only allowed in ARC or GC mode

I'm using wikitude, xcode5 and phonegap for my mobile app project. I got this error when I try to build the project.
/Applications/MAMP/htdocs/rmbp/apps/rmbp/iphone/native/WikitudeSDK/WTARViewController.m:19:1: @synthesize of 'weak' property is only allowed in ARC or GC mode

Why?

A:

Which PhoneGap version are you using?
Since PhoneGap version 2.1.0, ARC is enabled by default and you shouldn't have any problems. 
You might check your PhoneGap version and update to 2.1.0+ (current release is 3.3).
