Designing Dark Mode App Icons

Apple’s announcement of “dark mode” icons has me thinking about how I would approach adapting “light mode” icons for dark mode. I grabbed 12 icons we made at Parakeet for our clients to illustrate some ways of going about it.

Before that though, let’s take some inventory. Of the 28 icons in Apple’s preview image of this feature, only nine have white backgrounds in light mode. However, all icons in dark mode have black backgrounds.

Actually, it’s worth noting that five “light mode” icons have black backgrounds, which Apple slightly adjusted to have a consistent subtle black gradient found on all of their new dark mode icons. Four of these—Stocks, Wallet, TV, and Watch—all seem to be the same in both modes. However, no other (visible) icons are.

Fantastic showcase by Louie Mantia of how designers should approach the creation of dark mode Home Screen icons in iOS 18. In all the examples, I prefer Mantia’s take to the standard black background version.

Apple Details Its AI Foundation Models and Applebot Web Scraping

From Apple’s Machine Learning Research1 blog:

Our foundation models are trained on Apple’s AXLearn framework, an open-source project we released in 2023. It builds on top of JAX and XLA, and allows us to train the models with high efficiency and scalability on various training hardware and cloud platforms, including TPUs and both cloud and on-premise GPUs. We used a combination of data parallelism, tensor parallelism, sequence parallelism, and Fully Sharded Data Parallel (FSDP) to scale training along multiple dimensions such as data, model, and sequence length.

We train our foundation models on licensed data, including data selected to enhance specific features, as well as publicly available data collected by our web-crawler, AppleBot. Web publishers have the option to opt out of the use of their web content for Apple Intelligence training with a data usage control.

We never use our users’ private personal data or user interactions when training our foundation models, and we apply filters to remove personally identifiable information like social security and credit card numbers that are publicly available on the Internet. We also filter profanity and other low-quality content to prevent its inclusion in the training corpus. In addition to filtering, we perform data extraction, deduplication, and the application of a model-based classifier to identify high quality documents.

It’s a very technical read, but it shows how Apple approached building AI features in their products and how their on-device and server models compare to others in the industry (on servers, Apple claims their model is essentially neck and neck with GPT-4-Turbo, OpenAI’s older model).

This blog post, however, pretty much parallels my reaction to the WWDC keynote. Everything was fun and cool until they showed generative image creation that spits out slop “resembling” (strong word) other people; and in this post, everything was cool until they mentioned how – surprise! – Applebot had already indexed web content to train their model without publishers’ consent, who can only opt out now. (This was also confirmed by Apple executives elsewhere.)

As a creator and website owner, I guess that these things will never sit right with me. Why should we accept that certain data sets require a licensing fee but anything that is found “on the open web” can be mindlessly scraped, parsed, and regurgitated by an AI? Web publishers (and especially indie web publishers these days, who cannot afford lawsuits or hiring law firms to strike expensive deals) deserve better.

It’s disappointing to see Apple muddy an otherwise compelling set of features (some of which I really want to try) with practices that are no better than the rest of the industry.

iOS and iPadOS 18: The MacStories Overview

Image: Apple.

At its WWDC 2024 keynote held earlier today online and with an in-person event at Apple Park in Cupertino, California, Apple officially announced the next versions of the operating systems for iPhone and iPad – iOS and iPadOS 18.

As widely speculated in the lead up to the event, Apple’s focus for both OSes largely revolves around artificial intelligence, or as the company likes to refer to the AI acronym now, “Apple Intelligence”. The new AI features in iOS and iPadOS promise to make both operating systems, well, more intelligent than before thanks to a completely revamped Siri and proactive functionalities that learn from users’ habits and apps. Presented as a fast, private, and personal set of features that draws from the user’s context and combines it with generative models, Apple Intelligence – which will debut in U.S. English only later this year, with a beta expected later this summer – will power a variety of new system features and experiences, starting from a revamped Siri and text analysis features to image creation, performing actions inside apps, and more.

But AI-related improvements aren’t the only new features Apple announced today. From a renewed focus on Home Screen customization and redesigned Control Center to a new design for tab bars on iPad and expanded Tapbacks in Messages, Apple has showed that, while they can follow the rest of the tech industry in rethinking how AI can enhance how we use our devices, they can continue shipping other functionalities for iPhone and iPad, too. Or, at the very least, they certainly can for the iPhone and iOS.

We’ll have in-depth overviews for both iOS and iPadOS 18 when the public betas for each OS come out next month, and, of course, we’ll continue diving into the announcements later this week on MacStories via our WWDC 2024 hub as well as AppStories. We’ll also have a dedicated story about Apple Intelligence coming later on MacStories with the highlights of all the AI-infused features announced by Apple today.

In the meantime, here’s a recap of everything else that Apple showed today for iOS and iPadOS 18.

Apple Announces Vision Pro Launching in More Countries Later This Month

During its WWDC 2024 keynote earlier today, Apple announced that the Vision Pro will be launching in more countries and regions later this month.

Specifically, the Vision Pro will become available for pre-order in China mainland, Hong Kong, Japan, and Singapore on June 13, with availability starting on Friday, June 28. On the same day, pre-orders will go live for customers in Australia, Canada, France, Germany, and the United Kingdom, with availability starting on Friday, July 12.

From Apple’s announcement:

“The enthusiasm for Apple Vision Pro has been extraordinary, and we are thrilled to introduce the magic of spatial computing to more customers around the world,” said Tim Cook, Apple’s CEO. “We can’t wait for more people to see the impossible become possible, whether working and collaborating with an infinite canvas for apps, reliving treasured memories in three dimensions, watching TV shows and movies in a one-of-a-kind personal cinema, or enjoying brand-new spatial experiences that defy imagination.”

In addition to announcing availability in more countries and regions, Apple also showcased visionOS 2, the next major update to the Vision Pro’s operating system. Highlights from visionOS 2 include new gestures to invoke the Home Screen and Control Center, train Travel Mode, mouse support, and more. We’ll cover all the changes in visionOS 2 in a more detailed overview later today.

Josh King Built the iPhone Game Controller No One Wants to Make

I love this story that I first saw mentioned on Brendon’s blog a few weeks ago about a Redditor who designed the iPhone game controller of my (our?) dreams.

Picture this: it’s a PSP Go/Xperia Play-styled, slide-out controller that attaches via MagSafe to any iPhone, has Bluetooth, a USB-C port for charging, and therefore works with any modern iOS game or emulator regardless of whether the iPhone is mounted on it or not. The controller has a built-in kickstand that supports landscape and portrait gaming (the latter is essential for DS emulation in Delta) and is much more portable than other snap-on solutions available for iOS devices.

The best part: the creator of this controller, called the M-Con, has announced plans to make this a real product that you can buy in the future. You can watch the announcement video below:

As Jonathan’s story in last Saturday’s issue of MacStories Weekly showed, the dream for many of us right now is a compact, MagSafe-enabled game controller for iPhone that doesn’t use USB-C and allows the iPhone to be rotated. No official product that is not a 3D-printed adapter or DIY hack that does all that exists right now.

I wish Josh all the best in this adventure, and I hope to be able to purchase an M-Con game controller in the near future.

I Turned the New 13” iPad Pro Into a MacPad and Portable Gaming Display

The updated MacPad.

The updated MacPad.

As I hinted in my story on the issues of iPadOS last week, I upgraded from an 11” iPad Pro to a 13” iPad Pro (1 TB, Wi-Fi-only model). While I was very happy with the 11” form factor, I decided to return to the larger model for two reasons:

  • I wanted to have maximum thinness with the ultimate iPad Pro model Apple makes.
  • I sacrificed the physical comfort of the 11” iPad Pro to get a larger display for my MacPad as well as portable gaming.

Today, I will explain how I was able to immediately turn the brand-new 13” iPad Pro into a convertible MacPad using a combination of accessories and some new techniques I’ve been exploring. I’ll also share my experience with using the iPad’s glorious Tandem OLED display in a variety of gaming setups ranging from streaming to emulators.

Let’s dive in.

The One Where Quinn Nelson Tries to Create a Window with iPadOS’ Stage Manager

I’ve published my fair share of criticism regarding the iPadOS version of Stage Manager over the years. I wrote about it again last week, but most of its underlying issues date back to the original release in late 2022, which I documented here.

But let’s say you don’t want to read my articles and would prefer to have a more practical example of the issues I described. In that case, go check out this three-minute video by Quinn Nelson, in which he tries to have a Freeform window on the iPad and another Freeform window on an external display:

Post by @snazzyq
View on Threads

This video has everything:

  • It shows the confusing lack of Mission Control/Exposé to see all active windows for an app in Stage Manager.
  • It highlights the lack of a window picker in Stage Manager. Quinn points out that he can see a window picker on the iPad’s display, but that’s because the iPad is running in traditional Split View mode, which does come with the shelf.
  • Quinn is (rightfully) perplexed by what ‘Add Another Window’ means.
  • The video shows the inconsistencies of Spotlight as an app launcher.
  • It also showcases the inconsistent implementation of keyboard shortcuts for multitasking.
  • The video shows how downright unintuitive the solution is. An alternative solution mentioned in Quinn’s replies is equally non-discoverable.

I’m sure someone at Apple may argue that this is the kind of feature people buy another computer for. But it’s always the same story: if Stage Manager for iPad exists, what’s the point of leaving it in this state for two years?

The iPad Pro 2024 Manifesto

There are so many parts of Steve’s iPad Pro manifesto I would quote here on MacStories, but I’m going to limit myself to just a couple of excerpts.

What I like about this story is that it’s a balanced take on the limitations of iPadOS from the perspective of a developer, laid out in a comprehensive roundup. It serves as a great companion piece to my story, but from a more technical angle.

Here, for instance, is a well-reasoned assessment of why Stage Manager isn’t ideal for developers of iPad apps:

Stage Manager was such a missed opportunity: it tried to bolt-on a windowing model onto iPadOS without providing developers any way to optimize for it, and has had virtually no meaningful improvements in two years. What I really want to see are APIs. APIs to know when an app is running in Stage Manager and give it an opportunity to enable extra functionality to accommodate that — like having an ‘open in New Window’ context menu option that it would otherwise hide. APIs to set window size/shape, minimum and maximum size. APIs to open a window in split view if possible, with a preferred screen side. APIs to drag a window on mouse-down. Auxiliary views or inspector panels that can be floated on/near a primary window, like visionOS’ ornaments.

Many of these features are available as APIs to apps using the iOS SDK… on macOS and visionOS. Which is why it boggles the mind that iPad’s own Stage Manager spec completely shunned them, and ignored the explicit intent provided by developers as to how they want their apps to work. Stage Manager wasn’t provided as an opportunity to make our apps better, it was inflicted on developers in a way that harmed the developer, and user, experience. Which is why today you can very quickly stumble upon apps that don’t quite resize correctly, or have important parts of the UI covered by the virtual keyboard, or toolbars floating in strange places.

To this day, developers have no way to fine-tune their apps so that they behave differently (and better!) when Stage Manager is active. This part about JIT is also worth calling out:

Just-in-time compilation is essential to power things like web browsers, console and PC emulators, and language-based virtual machines. It is used by Apple’s own apps, like Playgrounds, to empower key functionality that no third party app can match. And it is provided in a very limited way (with a ton of asterisks) to Alternative Web Browsers in the EU under the DMA, so they can implement their own JavaScript engines. The DolphiniOS project, which emulates Nintendo’s GameCube, recently posted a video that perfectly encapsulates the problem and demonstrates why emulators for newer consoles just can’t come to iPadOS. Other app stores, like Microsoft’s Windows Store, offer a JIT entitlement as standard, and I think Apple should, too.

It’s not like JIT cannot exist on iPadOS; it’s that Apple has chosen not to offer it as an entitlement for third-party developers.

I also want to point out two more aspects of Steve’s manifesto. It’s almost a 1:1 match of a story he wrote for us in 2019, which is quite sad as it tells you a lot about iPadOS’ state of affairs. Five years later, and we’re still asking for the same changes. Additionally, it should be noted that Steve is not asking for Apple to call it a day and put macOS on iPad. Claiming that someone who criticizes iPadOS does so because “they just want the iPad to turn into a Mac” has become the de rigueur dismissal for some reply guys these days, and it completely misses the point.

I highly recommend reading Steve’s full story here.
