WWDC and Apple Doc

You can find so many blogs from online and a lot of related answers from the StackOver, but I will check WWDC and Apple managed documentations first to understand the latest technology and the story behide the scene.


Playground Practice

Personally I just like the Playground with Xcode very much. It can save the time on coding and debugging, plus verifying any idea immediately.


Thanks to the XCTest, we don't have to write the test cases in the code directly and managed two versions of the source as I did before. I checked the WWDC and wrote an easy test cases for a function to resize the NSImage in playground.
