If you were watching the WWDC keynote and felt like your screen was suddenly made of expensive, frosted glass, you weren't hallucinating. Apple finally pulled the curtain back on its "Solarium" project. It’s the kind of thing that makes your current iPhone feel like a relic from 2013. Honestly, we’ve been staring at the same flat, "Retina-optimized" icons for so long that any change feels like a shock to the system. But this isn't just a fresh coat of paint.
The Solarium interface is basically Apple’s way of saying "the iPhone is now a cousin of the Vision Pro."
For years, we’ve heard rumors of a design overhaul. Mark Gurman at Bloomberg was banging the drum about a "visionOS-inspired" look for months. He was right. Except, in typical Apple fashion, they didn't call it Solarium on stage. They branded it Liquid Glass.

Why the Solarium interface actually matters for your thumb
The tech world loves to argue about "skeuomorphism" versus "flat design." It's a nerdy debate that usually ends in a stalemate. But Solarium—or Liquid Glass—ends the argument by picking a third option: depth.
Think about how a window looks when the sun hits it at an angle. There’s a shimmer, a bit of refraction, and a sense of weight. That is exactly what Apple is doing with the Solarium interface. Buttons don't just sit on the screen; they float. They cast shadows that change based on how you tilt the phone.
It’s subtle.
You might not even notice it until you switch back to an older device and realize everything looks "dead" and static. The interface uses real-time ray tracing—yes, the stuff from high-end gaming—to calculate how light should pass through a "glass" button.

The death of the bottom navigation bar?
One of the biggest shocks at WWDC was the floating tab bar.
Historically, Apple has been obsessed with that row of icons at the bottom of your screen. In the new Solarium interface, that bar is gone. Or rather, it’s evolved. Now, you get a pill-shaped "floating" menu that sits just above the content.
It’s translucent. It’s tiny. And it moves.
When you scroll down a long article, the bar shrinks into a small dot. Flick your thumb back up, and it expands with a fluid animation that feels more like water than pixels. This isn't just for the iPhone, either. Apple is pushing this "consistency and unification" theme hard. Your Mac, your iPad, and even your Apple Watch are all getting the same "glassy" DNA.
What most people get wrong about the design
People keep saying Apple is "going back to 3D." That’s wrong.
Skeuomorphism was about making things look like leather, wood, or felt. Solarium isn't trying to trick you into thinking your phone is a physical notebook. Instead, it’s using transparency to give you a sense of hierarchy.
- Layering: High-priority alerts look "closer" to your eyes because they are more opaque and cast deeper shadows.
- Context: Background colors bleed through menus, so you never feel "lost" in a sub-menu.
- Adaptability: The "Liquid Glass" material actually changes color based on the time of day and your wallpaper.
It’s actually quite smart. By making the interface translucent, Apple is preparing us for a future where we might be wearing AR glasses. If your UI is already "see-through," it’s much easier to overlay it onto the real world without it feeling clunky.
The controversy: Accessibility and "The Blur"
Not everyone is happy.
If you go on Reddit or tech forums, there’s already a vocal group of users worried about legibility. "I survived the iOS 7 redesign," one user wrote, "I'll manage whatever this is." But the concern is real. Translucency can be a nightmare for people with visual impairments.
Apple’s solution is a new "High Contrast Glass" setting. It basically strips away the fancy light refraction and gives you solid, high-visibility borders. It’s a necessary trade-off. They are also leaning heavily on "Clear Mode," which is a middle ground between Light and Dark modes. It’s airy, minimalist, and—honestly—a bit distracting if you have a busy wallpaper.

How to get the Solarium interface look today
You don’t actually have to wait for the final public release in September to see how this feels. If you’re a developer (or just someone with a developer profile), the beta is already live.
- Check Compatibility: You’ll need an iPhone 15 or newer to get the full "Liquid Glass" effect. Older chips just can't handle the real-time light physics without turning your phone into a pocket heater.
- Update to the Beta: Go to Settings > General > Software Update > Beta Updates.
- Toggle the "Vibrancy" Settings: Under Accessibility > Display & Text Size, you can find the new toggles to increase or decrease the "Solarium" intensity.
The most important thing to remember is that this is the biggest shift since 2013. It changes how you tap, how you scroll, and how you perceive the "depth" of your screen. It’s a big bet on a spatial future.
Whether you love the "glass" look or hate the floating bars, the Solarium interface is here to stay. It’s the new language of Apple. You’ll probably spend the next week trying to figure out why your icons look like they’re made of sea glass, but eventually, the old "flat" look will just seem boring.
Actionable Next Steps
To prepare for the full rollout, start by cleaning up your Home Screen. The new interface relies heavily on "breathing room" and minimalism. High-density folders and cluttered widget stacks tend to break the "floating" illusion that the new UI is trying to create. If you use custom icons, be aware that many third-party packs won't support the new dynamic transparency effects until developers update them for the Liquid Glass framework later this year.
