Finally!
As a developer, I often need my IDE/Sublime open as I look up syntax. The lack of splitscreen support on Mac infuriated and confused me for such a long time but now I can finally look at two applications without taking the time to resize windows. My only complaint would be that I had to pay money for access to an easy to implement feature that all other OS’s have for free. However, if you need a mac for Xcode or Swift, this is a must have.
