Hi I have iMac with OS X Yosemite version 10.10.3 and I've installed the last Xcode 6.3 beta 2 with Swift 1.2 and when I try to Run the App I receive: Check dependencies Unable to determine compiler to use - the abstract compiler specification is missing from this Xcode installation.
and everytime when I open my project with Xcode I receive a warning: warning: no rule to process file '/Users/Bogdan-iMac/Desktop/My App/My App/My_App.xcdatamodel' of type wrapper for architecture x86_64 and I have to open Build Phases in Compile Sources I have to remove My_App.xcdatamodel and add it again to prevent the warning

I had the same problem here. The error disappeared after upgrading Yosemite to version 10.10.3 (14D87h) from today.
