Note that the video was created in 2015. As of May, 2018, Xcode is up to version 9.3, so yes, you are correct, the appearance of Xcode has changed a little.

Similarly, the current version of iOS is 11.3, whereas in 2015 it was 9.

The major difference (to my eye) is that working with constraints is a little different (easier) now. You don’t have to uncheck anything to switch to a constraint-based layout.

The code that moves over when I attempt to perform the assignment is not the same as the example. How am I supposed to know what the correct syntax is? All I get are a bunch of errors and I have run out of time.
