By day I lead mobile developers in collaborative, high performing teams.

By night I make my own apps and put them in the App Store!

I podcast fortnightly on a show called Waiting For Review with my friend Daniel Jilg.

Interested in all things tech📱

Cutting down lavender.. trimming and potting the cuttings

#Gardening #GardeningNZ
Lavender stems and flowers in a big red plant pot Lavender flower heads chopped off in a big red pot 6 pots with around 40 stems cut and planted on them. I put rooting compound on and used a mix of sand and potting compost

Further progress on my immediate mode Swift GUI today, toggles are working! 😅

Not pictured here but also today:
Multitouch

A type safe debug printer so I can mute different parts of the stack (at 60fps it gets spammy)

And a whole bunch of logic in the drag system

Sure yup, it looks a bit like this -
A screenshot from Xcode, showing my DSL, with code that looks pretty familiar to SwiftUI devs as it's very similar primitives. The naming convention is the same, just prefixed with VX (so VStack is VXVStack), so I can tell the difference when I'm developing

“Hello World”

ImGUI on iOS, running on top of ANGLE for the rendering engine. I’ve a lot more to do yet to make this useful for me but the bones are looking good 😀

The mental rabbit hole I've been prodding. Could I use ImGui via a C bridging layer, from Swift?

It's an idea that won't quit, which means I'll likely FAFO soon 🫠

Projector in my office, GoVJ running on an iPad with the camera facing to the output.

All it takes is a hand moving across and the ripples flow 🥰

I put a PaperLike screen protector on my iPad, to give it more feedback when drawing.

I had a bit of a noodle with Procreate. First time drawing anything in a while.

Lemon Jelly’s “Lost Horizons” art work. In a black frame on my wall. It depicts a gray city landscape on the left flowing into countryside in full vibrant colour on the right hand side. Above the city is “you are here” with an arrow. Above the countryside and sea on the right is “you should be here” with an arrow.

As always, coding-cat Stevie is along for the ride regardless as long as she gets scritches when desired.

Progress so far

A view of the app so far, with no video loaded. It has a black and CRT green accent to its UI. A view of the app with a video loaded. An effect preset is selected, "Vintage film", it is colouring the video a sepia-ish brown. There are effect parameters sliders on the screen

A couple of random loops + some blending and effects in GoVJ = having visuals fun 😀
