I once again was wondering what the correct/best toolbar button placement for sheet close buttons are. So, I’ve inspected how Apple places their close buttons. 🕵️♂️
Unfortunately it’s quite different across the system, so it’s a bit hard to see a strict pattern. Some apps are even inconsistent within themselves like Safari, Wallet, or Weather.

I can highly recommend not using a pure white background to improve the contrast of the toolbar buttons. Just a slight off-white helps a lot.
Now mix in a hint of a color to it and you even add a little bit of character. 😉 That’s what I do with my apps as well.

I wish Apple Mail’s empty view wouldn’t be that boring. I’m doing inbox zero and this is what I see when I reach my goal. 👌

The #GTAVI gameplay will be premiered on Netflix? What a weird choice.

Last week @datawrapper we launched the project I was working on for the last year or so. It’s a new visualization type: waterfall charts. 🌊📊

Cool to see Blender 5.2 – with the Liquid Glass icon I made – going live.
It isn’t anything out of this world, but it’s cool to have contributed to such an important piece of software…
Want to check how your website looks with Safari’s different bars?
I’ve just updated my little @Sketch design kit for liquid glass.

Close aka done:

Settings or confirm:

For me a settings sheet was always a bit of a trickier question, because settings are usually not saved on close, but applied directly. Though, the longer I look at it the more I feel like it makes sense to use a trailing checkmark in this…
A reason for the trailing placement is probably also the “Apple Account” branding or the placement of leading controls like segmented controls, search fields, and so on. Apps like Maps, Numbers, Wallet, Home, and Weather do this.
Though, o…
Feels like most often the close buttons are placed on the trailing position. To me that is probably a remnant of the old placement of the “Done” button of pre iOS 26 aera, which always placed it on the trailing side.

Great analysis of this year’s Liquid Glass design changes. Especially in regards of use of HDR.
