It’s presented as a historical artifact rather than as a living
project. It’s definitely not an example of how to write apps
these days — and it’s not even an example of how to write apps
in 2013. […]
It was written while iOS 6 was current, and it still looks like an
iOS 6 app under the hood. But, at the same time, we were
anticipating iOS 7, and so Vesper was an art project — we wanted
Vesper to join Letterpress and Twitterrific and a few others as
one of the first Modernist apps.
But we hadn’t actually seen iOS 7, and so we invented Vesper’s
look and feel from scratch, though with some idea of where the
puck was heading. That — combined with wanting to use Ideal Sans
everywhere, even in standard things like alerts — meant we had to
do a ton of custom UI and animations.
It’s interesting to me that 2013 was about the last time you could
plausibly think that that’s the right thing to do. It’s clearly
too expensive now — and was too expensive then, too, but we
hadn’t realized it yet.
The irony is that we thought Vesper was one of the first apps of a
new era — the era that officially kicked-off with iOS 7 — but,
in the end, it was one of the last apps of the era where it was
not uncommon for developers to spend massive amounts of time in UI
That last point is so true.
