after updating my NS app to latest version.. I am now suffering to run it on my iOS device..app simply does not open even though its installed. I was trying to run from xcode and got this msg on log :

**Class TKDataSource is implemented in both /System/Library/Frameworks/CryptoTokenKit.framework/CryptoTokenKit (0x1fdff00d8) and /private/var/containers/Bundle/Application/A97BDBFB-56E2-4303-A817-F582CEF25550/MYDOC.app/Frameworks/TNSListView.framework/TNSListView (0x104966e70). One of the two will be used. Which one is undefined.**

**ns run ios** shows this error :

**unable to apply changes on device: 7BE6C620-A73C-42DF-81AD-65A0083CB13E. Error is: ENOENT: no such file or directory, scandir '/Users/timmrichter/Library/Developer/CoreSimulator/Devices/7BE6C620-A73C-42DF-81AD-65A0083CB13E/data/Applications'.**

Any Idea?

Thanks
