We’re now releasing our RC version of the Titanium SDK with support for 64-bit builds on iOS.
A reminder that starting February 1st 2015, Apple will require that all new App Store submissions be compiled using the iOS 8 SDK, and support 64-bit architectures.. In an updated move, Apple is now allowing existing applications until June 1st, 2015 to complete the transition.
To test, please download the latest SDK build from the 3.5.0 stream (http://builds.appcelerator.com/#3.5.0). You do not need to download any CLI or Studio updates. You then just need to build your application using this latest version.
This build has no known issues for app deployment, thus the RC label. It does include a functioning debugger with a few remaining issues that will be resolved before the 3.5.0.GA on January 15th, 2015.
If you run into any issues, please file JIRA tickets and let us know ASAP.
