Titanium 3.4.0 doesn't recognize iOS 8 SDK

Why doesn't find Titanium my iOS 8 SDKs ? (see below Xcode 6.0.1, "iOS SDKs = none")

I followed the Appcelerator blog to use iOS 8. These are the steps I have taken:

1. I renamed Xcode 5.1.1 to /Xcode5.app in Applications folder

2. I downloaded and installed Xcode 6.0.1, and renamed it to /Xcode6.app in Applications folder

3. I downloaded the Simulators via Xcode->Preferences->Download

4. I upgraded Titanium Studio to Version 3.4.0.201409261227 and executed "sudo xcode-select -s /Applications/Xcode6.app/Contents/Developer", and refreshed the Titanium Studio->Preferences...->Studio->Platforms->iOS -> iOS SDK Home

5. I downloaded and installed Titanium SDK 3.4.0.RC2 and executed "ti sdk select 3.4.0.RC2"

6. I installed the NPM packages by executing

• sudo npm remove -g alloy

• sudo npm remove -g titanium

• sudo npm install -g alloy@1.5.0-rc3

• sudo npm install -g titanium@3.4.0-rc4

Now I get the following results:

a) ti info -t ios
