visionOS 3D content in SwiftUI | Xcode | Spline

[@seanallen]

Check out Spline at spline.design

[@alejmc]

I’m mind blown by this video and the Spline app (that came out of left field to me!) You guys are making it look so easy… this has been inspiring, motivating and all in between.

[@seanallen]

Hope you have as much fun building with it as I do

[@robotman011]

This is a pretty good resource. I was dealing with this exact issue lol. I like coding, not 3D modeling. So I will be hoping that Spline is my solution!

[@seanallen]

That's exactly what it's aimed to do. Let me know how you like it.

[@brianclear363]

love spline. i think it will be a great bridge between swift devs who cant get reality kit to look great or doo much and unity devs that only make games and unity's lack of interaction between swift/ios and and the unity runtime. It does need more apis to interact with the model. To change variables from swift and trigger events link animations. But their dev team seem to have a great roadmap. I wonder in the meantime can you interact with the model using realitykit hierarchy. Do you need to export it as obj then import it to RealityKit Composer and see if the nodes are named easily.

[@seanallen]

I agree completely. It's a great way for iOS devs to get into 3D design without the need to learn a heavy tool like Unity. Hopefully we'll see Spline get better and better as they progress through their roadmap.

Hey Sean, great video! I just did it all on my AVP, just one small problem... in immersive view, the model shakes, but if I hold my head still it stops shaking. I see a message, sort of... I think it says head-anchored content - Content will be head-anchored while debugging . I'm on the latest VisionOS 2 , so I'm wondering if there may be a code update for this ?

[@lucascouto1809]

Great video Sean! How would I add passthrough to the Immersive view? I added "mixed" to Immersionstyle but my scene is still all black.

[@JasonMitchellAZ]

Super cool! Can't wait to try this out... after I do the several updates I need to do on my current app! 😆😬

[@seanallen]

Get those updates done!

[@JasonMitchellAZ]

@@seanallen working on it 😉

[@tacojohnellenich]

Animation support can't come soon enough!

[@seanallen]

Agreed! visionOS and very new but I'm excited to see how these products evolve. That's why I'm playing around and learning this 3D design stuff now.

[@kyle-roche]

It’ll be great when they release event support

[@seanallen]

Agreed. The roadmap looks promising.

[@splinetool]

Hi! Events are already supported (although not all events are supported yet). We will continue working on it.

[@alexsafayan7684]

Great video! What shortcut did you use to convert the `content` parameter to a closure at 16:02?

[@alexsafayan7684]

For future reference: enter

[@seanallen]

Haha, yup. Glad you figured it out :)

[@nivleckone9106]

I wanted to get started developing for the visionOS but I need to buy a Mac with apple silicon, which one would you recommend?

[@seanallen]

The highest spec you can afford. I know that's vague, but it's the truth.

[@Meekismwisdom]

Hey Sean! What app is that at 3:38 ? great tutorial

[@chuchoonce]

Do you consider a MacBook Pro M3 Pro 18GB RAM / 512 SSD enough for visionOS?

[@harold_davis]

Fire!

[@seanallen]

Glad you liked it!

[@MaksymovaD]

The workflow of Spline looks so much like the workflow in Figma! including mirror, community, browser version, UI... I wonder how the two are related. does anyone here know?

[@ghenaalghaayeeni]

Do I need to have mac os in order to use swift UI?

[@asastudios7782]

You can't run xcode on windows

[@ParthKanani555]

How is the scope of iOS app development in 2025 or future?

[@seanallen]

Here's my philosophy. When you become an iOS developer and learn Swift you are tying your career to Apple. If you think Apple has a future then it's a good bet.

[@obvinpro]

Vision platform will not take off but glasses will with hologram kinda interface not 3D

[@seanallen]

Over the years Apple Vision Pro will get lighter and thinner (maybe even in a glasses form factor). I think the platform is here to stay

[@SchoolBads]

Unfortunately immersive space doesn't work

[@seanallen]

Can you elaborate? I mention in the video some of the pre-existing assets in the library aren't compatible with visionOS (yet... they are working on it). Are you using the same assets I am?

[@SchoolBads]

@@seanallen yes, I literally just copied the url from your video

[@seanallen]

Hmmm... tough to say without seeing your code. I just pulled it up in Xcode and it worked. What error are you getting?
