I'm working with xcode 6.0.1 and when I add a new file of type SpriteKit Particle and push the button SKNode Inspector to edit the properties, an assertion is produced.
The error is:
ASSERTION FAILURE in /SourceCache/IDEFrameworks/IDEFrameworks-6528/IDEKit/Inspectors/IDEInspectorCategoryController.m:159
Details: **All objects must have type identifiers**, <SKScene> name:'(null)' frame:{{0, 0}, {760, 659}}, represented by <SKDocumentNavigableItem 0x7f8d3d71e0d0: (supports Any SKScene, represents: <SKScene> name:'(null)' frame:{{0, 0}, {760, 659}})> does not.
Function: NSSet *IDETypeIdentifiersForNavigables(NSArray *__strong)
Thread: <NSThread: 0x7f8d39e19c20>{number = 1, name = main}

This error is launched when I push the button in the XCODE IDE SKnode Inspector.
