Private _UIFlexInteraction that powers all LiquidGlass interactions.
If Xcode autocomplete stops working or takes forever to show up: → Run killall SourceKitService in the terminal. Absolute game changer.
This has the energy of a kid discovering spring animations for the first time 😭
There’s a neat trick you can use on iOS 26 when working with a menu: if you apply a rotation transform to the view that spawns the menu, you’ll get a playful rotation for free!
The Next button is disabled, yet it appears more prominent than the Cancel button (which is enabled). Even more confusing, you can still interact with it, but its action won’t be triggered. Totally misleading 🤦♂️
Our team has been working tirelessly to make this happen. This is about our kids’ future.

Hands off the keyboard, it’s perfect now. Somewhere between webOS and LiquidGlass 🥹

YES! I finally cracked it. If you’ve used CALayer, you know how tricky it is to cast a shadow without visible content. Turns out it’s trivial! You need to set those two private properties:
Another one: CALayer supports inner shadows through a private property. You don’t need a complex setup where you invert a CGPath and create a cut-out. Just set the invertsShadow property to true.
CALayer has a (private) concept called a rim. A rim is similar to a border, except it’s drawn outside the CALayer, whereas a border is drawn inside. There’s even a softRim property that gradually smooths the rim toward the outside. Neat!
