Can't even run an empty C++ Project on iOS device

I am just starting out and trying to run Unreal Engine 4.5.1 on Mac. The Mac builds seem to run okay but when trying to build for iOS the app starts to run on iOS then crashes on an assertion related to “ICU data directory was not discovered:” A screenshot of the assertion is below.

I understand that I cannot build for iOS, on a Mac, using Blueprints but any suggestions on how to fix this error using Xcode?

Mac is 2010 MBP running Mavericks, and the iPhone is an iPhone 6 plus running iOS 8.1.

Thanks in advance!

Hi,

The reason that is failing is none of the data for iOS has been cooked. You will need to build the editor for your project, run it and open your project, and then utilize either Launch On or File/Package/iOS and that will then cook all of the data and stage it for use. Then running from within Xcode so you can debug the program should get past that particular error.

Ah perfect thanks I missed this information somewhere.

This was the solution for me as well. Was having this exact problem. Thanks Pete!
