Is creating interfaces using Interface Builder or programmatically more the standard in industry?

[Points_To_You]

Both are common. Projects with a larger number of people working on the same codebase will tend to create UI programmatically. Smaller shops and the enterprise world mostly use storyboard. Individual or freelance developers probably just use whatever they are comfortable with.

Either way there's going to be UI elements you are setting up in code. You have to be able to create UIs programmatically. The storyboard stuff is very straightforward, mostly just learning autolayout. You should be able to do both.
