I am a newbie in this field of development. I started using Xcode 6 after using Xcode 5.1.1 for a week.
After getting fascinated with newly added features, I installed Xcode 6.
Now, I am not able to find this 3D view of UI in ios.
I am using OSX 10.9.4.
Worth noting for this problem is that if you're running a 64bit device, your target needs to be configured so that arm64 is in both your Architectures and Valid Architectures build settings.
If you don't have that, you can debug your views on a 32 bit device, but not 64.
