[AC-322] iOS SDK Home Not specified!

Appcelerator Studio 4.1.12 can't get my Xcode location info. iOS SDK Home is not specified in Platform's iOS preferences. I've tried every single solution on the web, but in vain. I've tried xcode-select, updating node.js, also the "npm install titanium -g", reinstalling JDK, and still can't setup iOS SDK Home. Refreshing doesn't work of course This is the result of "appc ti info -t ios" in terminal:

No issues detected! Your development environment should be working perfectly!

Also I get Java runtime exceptions when opening the iOS section in Studio/Platform preferences as well as when opening TiApp.xml while getting Appcelerator Platform information.
