Here we go. Apple does not make it as easy as it seems.
Setting up Development Environment
Installed Yosemite and downloaded xCode.
From the Swift Resources page downloaded and loaded eBooks, but this browser link is better.
eBook recommended to download GuidedTour.playground.zip which I did and loaded up xCode by double-click.
Now it gets stupidly hard because I use a regular account and this is not well documented to explain what exactly I need to do,
Developer Tools Access needs to take control of another process for debugging to continue. Type the name and password of a user in the "Developer Tools" group to allow this.
Research on above message shows sample command which I read through man files to verify,
su - setup.admin # account I use for administration sudo dscl . merge /Groups/_developer GroupMembership tin.pham # merge first checks if you are already have the group versus append exit groups # result of this command should now show _developer
Loaded playground but it did not load any other windows.
Rebooted Mac OS X and still same thing.
Went through this video tutorial which kinda worked except for the rectangle draw line.
Also found this tutorial.
