Two hours on a train without WiFi means reverse engineering the Liquid Glass...liquid...effect? Reasonably simple API to work with: CASDFLayer, CASDFElementLayer and a CASDFEffect subclass, in this case CASDFFillEffect. You can wrap up in a UIView subclass, overriding layerClass to play nicely with higher-level UIKit animation abstractions.

Spent some time reverse engineering Apple Music and Podcast's search chips UI 👀 Interestingly, there's no public or private API to achieve this, _and_ both Music and Podcasts have different implementations of the identical interface 🫠 Anyone interested in an article on this?

It's hard not to add fuel to the "is SwiftUI production-ready" fire when this is the state of the "best way to build an app" 6 years after the framework was released... 🙃 ~30 lines of (admittedly sloppy) but simple code, unusable on iOS 26. Oh! And it works just fine on 18 🫠

With a bit of UIKit Jiggery-Pokery™ you can display arbitrary views as the content of a segmented control’s segments. In this case, a _UIHostingView featuring SwiftUI Text with an animated numeric content transition. Although probably doable _with_, no private APIs used here!

Spent some time preparing Duet for iOS 26. Pretty happy with how this interaction turned out! In a shocking turn of events, I ended up using SwiftUI for the two map style buttons because, despite UIButton.Configuration being great, it’s got noting on SUI’s ButtonStyle API.

All of that work for what ended up being a very subtle effect... Happy with it though! Was worth the extra effort getting it working with UIKit's block-based animation APIs. Means I can use UIViewControllerTransitionCoordinator's animate(alongsideTransition:completion:) 🤓

Been a while, but here's your private API of the day... UIKit's fluid slider, as seen in Apple Music, Podcasts, SpringBoard and more. UISlider has private `_sliderStyle` and `sliderConfiguration` properties. Here, the slider has a style of 110, and the configuration is an instance of the private `_UISliderFluidConfiguration` class.

I promised you a zinger, so here's your private API of the day... Meet _UIContextMenuAccessoryView and UIContextMenuInteractionDelegate_Private's _contextMenuInteraction(_:accessoriesForMenuWithConfiguration:) method. This enables iMessage-like accessory views to be displayed alongside a context menu. Quite a lot going on here, so let me know if you're interested in a blog post 👀

Interesting new private property of UINavigationItem added in iOS 18, _preferredNavigationBarVisibility. This is really handy if only your detail view requires a nav bar. No need to set isHidden in viewDidAppear(_:) and viewWillDisappear(_:). Here's an example in Duet...

Ooh here's a fun one! 👀 UISheetPresentationController.Detent has a private _fullDetent method that, when applied to a UISheetPresentationController's detents array, enables switching between a sheet and a full screen modal with a gesture... Super clean interaction!

Spent some time reverse engineering the Apple Maps sheet UI on iPad. This can be achieved with a few private UIKit APIs... 3 private properties of UISheetPresentationController: horizontalAlignment, wantsBottomAttached and marginInRegularWidthRegularHeight. Code below... 👇🏽

Here’s your reminder that, if you’re triggering an animation on -[UIViewController viewDidAppear], you should probably create an ivar that keeps track of whether or not you _need_ to start said animation 🙃

3D, folding map view built with MKMapView and a few well organised _UIPortalViews... Used CATransformLayer and CATransform3D to create the 3D effect. All animatable with UIKit animation APIs too which is a nice bonus - UIViewPropertyAnimator doing the work here.

Custom view controller transition I built at work this week. A few interesting engineering challenges… 1) Presenting the half sheet during the custom transition. 2) Animating the frame/transform of an MKMapView! 3) Ensuring continuity of the activity indicator before/after the transition begins/ends. Details below 👇🏽
