Reasons to create UI in code rather than storyboard

Avoid Storyboards

Reasons to create UIs in code rather than Storyboards:

Merge conflicts 

Easier to diff revisions and see changes in code

More flexibility to move UI elements on iPad vs iPhone,
portrait vs landscape

Easier theme support

Easier to animate views

Easier to hide/show views

Faster layout at runtime

Interface Builder is a hassle when deleting or moving views
with autolayout, often requiring us to delete and recreate a
bunch of constraints.

Easier to share a source file between projects than a source
file and piece of a storyboard or even a xib

We can write custom view code that runs on Macs and iOS if
we're careful, which is very hard to do with Interface
Builder.

Storyboards have magic values in them that have to match
magic values in code, for example segue identifiers. It's
very easy for typos to result in runtime misfires.

Having said all of that, we do prototype in storyboards at
times and they're certainly useful for simple apps.

I agree with you my friend. Typos that cause NSException.
