Unable to build apps with Xcode 7

Hi, I upgraded my Xcode to version 7. After that, I cannot build my app with this error message:

--

The following build commands failed:

[ERROR] : Compile Asset Catalog Build/Products/Debug-iphonesimulator/MyApp.app Assets.xcassets

[ERROR] : (1 failure)

--

This occurs in both ios simulator 8.4 and 9.0.

Appcelerator version is 4.3.0.201509151348 and Titanium SDK version is 5.0.0 GA.

Does anyone know how to solve this? Thanks
