• I saw this a few times and found that clicking repeatedly on the project name in Titanium would sometimes fix the issue.

• If you run this in a Terminal window, do you get an output?

  /Developer/usr/bin/xcodebuild -showsdks
  

  Also, please be more specific: "iOS latest build SDK"

  Is it XCode 3.2.4? XCode4 Preview?

  BTW - If you only have the XCode4 Preview installed Titanium will not be happy because it searches for the iOS SDK in /Developer and the XCode4 Preview is in /XCode4.

• Hi,

  .DMG file downloaded from Apple today was 'xcode_3.2.4_and_ios_sdk_4.1.dmg' and the output from the console was:

  Mac OS X SDKs:
      Mac OS X 10.5                     -sdk macosx10.5
      Mac OS X 10.6                     -sdk macosx10.6
  
  iOS Device SDKs:
      Device - iPhone OS 3.2            -sdk iphoneos3.2
      Device - iOS 4.1                  -sdk iphoneos4.1
  
  iOS Simulator SDKs:
      Simulator - iOS 3.2               -sdk iphonesimulator3.2
      Simulator - iOS 4.0               -sdk iphonesimulator4.0
      Simulator - iOS 4.1               -sdk iphonesimulator4.1
  

  Any further help would be great.

  To others that have had this issue, as per other threads download the latest build of the Mobile SDK from : Appcelerator Builds.

  At the time of writing this is was 4.2.0, extract the folder in osx to /Library/Application Support/Titanium/mobilesdk/osx/

  This is where it differs for most people, mine didn't just come alive after this and make the drop down work, I had to delete all projects and then reimport them for the selector to work again.

  Hope this helps other people in the same situation.

• If you updated from previous version, you must change SDK to use in your project. This solved my "loading" issue in Mac OS X.
