One day there will hopefully be a house on this land Over the last year, I admittedly haven’t used my Vision Pro a ton, but fairly recently I discovered a super handy use that it’s absolutely incredible at, provided you have the right tools.

Hard to believe, but it’s been over 9 months since the current crop of iPhones came out, and I elected to grab the (apparently not super popular) iPhone Air, a new model of iPhone introduced for the first time.

The Apple Watch is one of the most fascinating pieces of modern technology for me.

After 7 years with a Tesla Model 3, we picked up a gen 2 Rivian R1S in April of 2025.

I didn't know what to put as a header so here are some iClouds (interesting clouds) in Maine I’ve had a lot of fun working with CKSyncEngine over the last month or so.

One trick doctors hate that will make your iPhone… Sorry.

Okay, I have to be doing something astronomically stupid, right?

While the GIF format is a little on the older side, it’s still a really handy format in 2025 for sharing short clips where an actual video file might have some compatibility issues.

My favorite memory of my M1 Pro MacBook Pro was the whole sensation of “holy crap, you never hear the fans in this thing”, which was very novel in 2021.

I upload YouTube videos from time to time, and a fun comment I often get is “Whoa, this is 8K!”.

Recently there’s been very exciting developments in the Godot game engine, that have allowed really easy and powerful integration into an existing normal iOS or Mac app.

Spoiler: 3D printed!

Hey I'm a developer not an artist Following my last blog post about difficulties surrounding UserDefaults and edge cases that lead to data loss (give it a read if you haven’t, it’s an important precursor to this post!)

Excuse the alarmist title, but I think it’s justified, as it’s an issue that’s caused me a ton of pain in both support emails and actually tracking it down, so I want to make others aware of it so they don’t similarly burned.

For those not aware, a few months ago after reaching out to me, YouTube contacted the App Store stating that Juno does not adhere to YouTube guidelines and modifies the website in a way they don’t approve of, and alludes to their trademarks and iconograph…

iOS 17.2 gained the capability to start Live Activities from a server, which is pretty cool and handy!

I designed my own keyboard and it’s freely available!

Juno is an app I built for watching YouTube on the Apple Vision Pro, and it’s been such a fun project to build.

I love the “carry-on only” traveling style, it’s cheaper and you don’t have to worry about airlines losing your stuff.

People were really kind and seemed to enjoy my 3D printable Apple Vision Pro stand, a stand I designed in Fusion 360 with the goal of being visually appealing and compact as it stored the headset vertically so it wouldn’t take up too much space on your de…

Using MagSafe for portable battery packs has so many niceties versus Qi1: Increased communication with the device, allowing for better efficiency due to better thermal management and charging Easily view the charge percentage of the external battery when…

Disclosure: Waterfield sent this in exchange for a review.

Many of Apple’s own visionOS apps, like Music, Safari, and Apple TV, have a handy search bar front and center on the window so you can easily search through your content.

In building Juno, a visionOS app for YouTube, a question that’s come up from users a few times is whether it supports 360° and 180° videos (for the unfamiliar, it’s an immersive video format that fully surrounds you).

I want somewhere to put my Vision Pro when not in use.

If you’re new, Juno is a visionOS app for YouTube!

YouTube is probably one of the parts of the internet I consume the most, so I was more than a little sad when YouTube announced that they don’t have plans to build a visionOS app, and disabled the option to load the iPad app.

Autonomous was nice enough to send me one of both their Smart Desk Pro standing desks and ErgoChair Pro chairs in exchange for posting about them on Twitter, and I wanted to cover them in more detail on my blog as well so I could give my full thoughts on…

If you’re like me, you often have multiple versions of Xcode installed.

Apple has a really awesome WWDC 2018 video called Designing Fluid Interfaces, and one of the key takeaways from the videos that one of the presenters, Chan Karunamuni, said is “Look for delays everywhere.

Converted the blog over to a new Hugo theme!

Theming apps (the ability to change up the color scheme for an app from say, a white background with blue links to a light green background with green links) is a pretty common feature across a lot of apps.

I wrote a new little view for a future version of Apollo that makes some changes to the default iOS version (that seems to be a weird trend in my recent programming, despite me loving built-in components).

Skip to the ‘Juicy Code 🧃’ section if you just want the code and don’t care about the preamble of why you might want this!

I think it’s safe to say while the iOS custom view controller transition API is a very powerful one, with that power comes a great deal of complexity.

Lately users have been emailing me with a few odd things happening with their Apollo iOS 14 home screen widgets, and some well-placed logs can really help with identifying what’s going wrong. iOS has a sophisticated built in logging mechanism, os_log, and…

PHPickerViewController is (in my opinion) one of the more exciting parts of iOS 14.

Apollo 1.9’s a massive update to Apollo that’s taken months and months to complete, but I’m really happy with the result, and it brings together a ton of ideas from the community to make Apollo even nicer to use.

I tweeted today about how I think TestFlight review should become a thing of the past and many developers seemed to agree, but some had questions so I wanted to expand on my thoughts a little.

I’m really excited to unveil a project I’ve been working on for the last year or so.
