Sharing Links from Twitter for iOS Appends Garbage to the URL→

Last night on Twitter, I noted that the company’s iOS app now appends a query parameter based on an app’s bundle identifier when you share a tweet’s link via the system share sheet.

As some have noted, this appears to be a recent change in Twitter for iOS, which is less than ideal as the resulting link contains a long string of URL-encoded garbage. More than ugly URLs, however, what bothered me was Twitter’s implicit tracking of which apps users invoke to share links with – something that even applies to core iOS features such as Apple’s own Messages extension.

I wondered whether Apple should consider this a violation of App Store guidelines, but it appears that Twitter isn’t breaking any rules by appending app-based query parameters to their shareable URLs. Benjamin Mayo looked into this feature and explained how Twitter is leveraging public iOS APIs to read bundle identifiers from the share sheet – he even posted a proof-of-concept code snippet to show how it’d work in practice.

He writes:

In reality, this is very easily achieved. As part of the activity provider API, the system asks for content to share for each sharing extension the user has installed. The Apple framework openly passes the activity type to the app. Twitter simply takes the base URL it wants to share and appends the ‘garbage’ before returning.

And:

The important thing to note here is that the mechanism is innocuous and uses valid APIs provided by Apple. Twitter is not exploiting private APIs to achieve this. A cursory look at the app review guidelines suggests to me there are no grounds for Apple to scold Twitter (or any other app) for doing it.

My personal stance is that this is annoying but does not violate user privacy. Importantly, Twitter cannot append arbitrary information to its URLs system-wide; it is confined to cases where users share something from inside the Twitter app itself. I don’t really see a justification for Apple to amend the guidelines to disallow it. I just take it as another reason not to use the official Twitter app.

In conclusion, if links to tweets you copied from the Twitter app suddenly look longer and messier than before, this is why. Personally, while Twitter may be taking advantage of a publicly available API, I still think the implementation is, at the very least, in poor taste – especially because it’s coming from the same company that used to scan users’ devices to list installed apps and deliver “tailored content” based on them. Even though I won’t stop using the Twitter app because of this, I wish Twitter would revert to standard, clean URLs when sharing tweets from the app. I also hope Apple is taking a closer look at this.

Aquarelo: A Beautifully-Designed Mac Color Utility

There are a seemingly endless number of ways to represent colors. Whether you’re a professional designer or developer, or someone who just wants to update a website template, you’ve undoubtedly come across several. The trouble with so many different formats is that it guarantees that at some point, the color value you have won’t be the one you require. Aquarelo is a beautifully-designed new Mac app that cuts through the thicket of formats to help you find the colors you want and convert them to the format you need.

Matt Wilkinson Joins Beats 1’s Primetime Lineup→

Serenity Caldwell, reporting for iMore on a major change to Beats 1’s primetime lineup:

Apple’s Beats 1 radio service (part of Apple Music) is shaking up its weekday primetime programming starting January 8, bringing a new DJ to its daily lineup and moving around its primetime shows.

Matt Wilkinson, who formerly hosted Beats 1’s weekly Saturday alternative music show, will now join Zane Lowe, Julie Adenuga, and Ebro Darden as a weekdaily presence on the network — he’ll be broadcasting live from London from 6AM-8AM ET Monday through Friday, and will have Mike D of the Beastie Boys on to celebrate his new show on January 15.

Wilkinson’s deep music knowledge (he’s the former NME New Music Editor) is a solid addition to Beats 1’s regular programming.

Here’s Caldwell again on the significance the announcement:

This is the first time since Beats 1’s launch in 2015 that the primetime lineup has changed significantly: Adding another London voice at the 6-8AM ET slot will nix many of the replays and countdown shows formerly occupying that space; in addition, Julie Adenuga is moving from 3PM ET to 9AM ET, with Ebro Darden bumping up to the 3PM ET slot from the 6-8PM ET evening beat. Beats Creative Director Zane Lowe will continue to hold his flagship 12PM ET slot.

I haven’t listened to Beats 1 much over the past year, but I’m going to check out Wilkinson’s new show (to get an idea of Wilkinson’s style, you can listen to his last show of 2017 – Episode 128 – here.)

Reverse-Engineering the iPhone X Home Indicator Color→

Nathan Gitter:

I noticed an unusual behavior of the iPhone X home indicator while working on my most recent app. The app’s background near the home indicator is purple. When the app launches, the home indicator is very light gray.

But something odd happened when I pressed the app’s “share” button, which opened a default iOS activity view (aka “share sheet”). When I hit the “cancel” button to close the activity view, the home indicator animated to a dark gray color.

Home indicator starts light, then a share sheet passing makes it dark.

Even though the background color was exactly the same, the light-colored activity view passing underneath caused the home indicator to change color. The only way to get the home indicator back to its original color was to leave the app and come back.

I had never seen this before, and it prompted my curiosity.

Fascinating study of the iPhone X’s Home indicator behavior. I had no idea that the indicator adapted to background color changes within the bar itself. Don’t miss the second (and more technical) half of the story with Gitter’s detailed color tests.

Jamf Now: Easily Set Up, Manage and Protect Your Apple Devices [Sponsor]

For some people, IT is a task and not a career. Jamf Now helps you manage and secure your iPad, iPhone and Mac devices at work.

For example, when a business is first starting out, it’s pretty easy to keep track of a couple of Apple devices. But as a company grows and it start to buy more tech for employees, it gets harder to keep track of everyone’s Mac, iPhone, and iPad. Figuring out how to secure an iPad that an employee lost can be tough — especially if they work remotely.

Jamf Now makes that, and much more, easier. You can check real-time inventory, configure Wi-Fi and email settings, deploy applications, protect sensitive company data, and even lock or wipe a device from anywhere. Jamf Now helps manage your devices so you can focus on your business. There’s no IT experience needed.

MacStories readers can start securing their business today — by setting up the first 3 devices for free. Add more, for just $2 a month, per device. Create your free Jamf Now account today.

Panic to Discontinue Development of Transmit iOS→

Panic has announced that it will remove Transmit iOS from the App Store soon. In a blog post today, Cabel Sasser explains that the revenue generated by the paid-up-front app was insufficient to justify its continued development. Sasser doesn’t rule out a return of Transmit to iOS some day, and the move does not affect the company’s other iOS apps or Transmit 5 for the Mac, but adding features to the iOS app to match those debuted in the Mac version last year would make Transmit iOS ‘a guaranteed money-loser.’

This is not Panic’s first pull-back from the App Store. In 2016, Panic pulled the plug on Status Board, its widget-style app for tracking data through web APIs. Why Transmit wasn’t sustainable on iOS is unclear:

Was the use case for this app too edge-casey or advanced? Did we overestimate the amount of file management people want to do on a portable device? Should we have focused more on document viewing capabilities? Maybe all of the above?

Although Transmit will be removed from the App Store soon, Panic updated it with iPhone X support, and existing users will still be able to download it from the App Store and use it until some future change in iOS breaks the app.

I’m sad to see Transmit go. It’s a loss for the platform, but I don’t think it’s a bad omen for ’pro’ iOS productivity apps in general. Transmit failed to get the traction necessary to sustain its further development, but there are still many examples of productivity apps that have found success on the App Store. Hopefully, Panic will find a way to bring Transmit back to iOS one day.

Track Hyper-Local Weather Conditions With the Netatmo Weather Station

For some people, weather apps simply answer questions like ‘Do I need a coat today?’ but their appeal is much broader. Weather apps are also about science and statistics. If you enjoy the geeky data side of tracking the weather, there’s no better way satisfy that interest than by collecting measurements yourself with a weather station like the one made by Netatmo.

Weather stations, like many gadgets, run from the simple to the complex. What I like most about the Netatmo Weather Station is that it’s easy to set up and modular. That means you can start with the core system that tracks basic weather data like temperature, humidity, barometric pressure, and air quality, and later, add wind speed and precipitation gauges if you want to dive deeper into tracking the weather.
