WatchOS 5 adds support for web content rendering

Apple recently announced updates to the core software on all of their hardware platforms with various interesting new features.

One feature that jumped out when looking through it all was support for displaying web content in watchOS 5, it’s important to clarify that they haven’t added a standalone Safari app to watchOS but instead it enables any links sent via Mail or Messages to be accessed and then displayed right on the watch.

To get a quick overview it is worth taking a few minutes to watch the “Designing Web Content for watchOS” video on the WWDC2018 videos site as it gives a good overview.

Here’s a few thoughts and info about key aspects that I picked up from watching the video:

User navigation / interaction

  • You can scroll using the Apple Watch’s digital crown or via pan gestures
  • Double-tap to zoom in / out on the page content
  • Back/Forward navigation is controlled either via an overlay UI brought up via a  firm press on the screen or by swiping back and forward from the edges of the screen.

Web browser feature support

Content is optimised for display on the Apple Watch so certain features are not supported in watchOS 5:

  • Video playback
  • Service workers
  • Web fonts

If the web content being accessed is responsive then it treats the content as being 320px wide, the same width as if on an iPhone SE (iPhone 5 or older width). So text may be smaller but at least it will basically render the smallest breakpoint content, so it doesn’t require any new even smaller breakpoint to be catered for.

This is done by overriding the “initial-scale” value and provides a viewport with the dimensions 320px by 357px and reports a media query size of 320px. So existing responsive content will render on the Apple Watch without requiring any changes – at least from a layout perspective, worth noting the lack of support for Web fonts as this will likely have some rendering impact as it falls back to alternative fonts in the font stack do display.

Optimising content for Apple Watch

Even though responsive content will be rendered quite well by default it is possible to optimise content for display on Apple Watch.

The above image shows the standard responsive content being displayed on the Apple Watch, basically just the same as it would be on an iPhone SE (minus any web fonts of course!).

Responsive Layout on Apple Watch

Using a media query it is possible to modify this layout to display as a single column. There is an example given in the video which obviously won’t apply for all uses, but basically it uses “min-width: 320px” as the baseline for showing the content as two columns, so any content below that would render as a single column. Again, how this works specifically for your layouts will vary, but there will be some methods to use for frameworks like Foundation or Bootstrap etc.

“Disabled-adaptations” meta tag

The important addition to using a media query though is a new meta tag which disables the default adaptations that the Apple Watch makes when rendering content by default:

<meta name=”disabled-adaptations” content=”watch”>

With this meta tag in place the device width will be treated as the real width of Apple Watch’s screen. This again has similarities to how content was handled when the iPhone originally came out, existing content is displayed as best as possible but there are ways to optimise for the device if you want to.

Form controls on watchOS

Making use of HTML5 form control types is really important on watchOS, setting the type attribute to “email”, “tel” etc will bring up a specific, full screen UI to allow interaction.

Additionally making use of labels, placeholder or aria-label attributes enhance the context given when interacting with these controls. Hopefully you’re using these already but here’s another reason to do so.

Safari Reader on watchOS

This is a feature found on iOS and macOS which basically formats pages to show a more readable version of web page content. It’s a little unclear from the video but it sounds like pages that are “text heavy” will get displayed using Reader, although I’m not 100% sure how that would be determined exactly if so. Perhaps this is a way to handle big pages that might have a lot of adverts on it? Reader view is an option that users can choose by firmly pressing on any page to bring up the navigation overlay, so even if content is displayed normally a more readable version can be accessed.

Semantic markup in Reader view on watchOS

Reader view makes good use of semantic markup, using the “article” tag helps the display of content, and attributes like “item-prop” and other semantic tags like “strong”, “em”, “blockquote” etc enhances the display of content in Reader on watchOS.

Open Graph meta tags

Using Open Graph meta tags is something that makes sharing content around the web such as into Facebook, Twitter etc look better by providing specific preview content such as images, titles etc. watchOS makes use of these Open Graph meta tags to make the previews for any shared links look as good as possible.


That’s a quick overview of some aspects of watchOS 5’s support for web content, there’s definitely a few things to consider in there but if you’re building pages using responsive layouts and using semantic HTML then things should work fairly well without having to do anything.

The biggest issue I see initially is the lack of support for web fonts, that seems like it could cause some display issues due to the fallback to alternative fonts in the stack or if web fonts have been used for icons etc.

I’m also interested to know what the impact on battery life on the watch is like when loading and rendering multi-megabyte web pages which are not uncommon these days, I think Reader view is going to be an essential feature for viewing web content on Apple Watch.

GDPR, Privacy and WordPress

Over the last few weeks and months if you’ve been on any kind of email subscription list you have undoubtedly had at least one email (likely with a pleading tone!) asking you to re-confirm your permission to receive emails. These emails have all been prompted by the new General Data Protection Regulations, or more commonly by the acronym GDPR which is in force under EU Law as of May 25th 2018.

These impending regulations coupled with the fallout from the high profile Facebook / Cambridge Analytica data mis-use has brought the whole issue of data protection, privacy and handling of user data to the forefront of people’s minds. The consequences of mis-use of personal data provided to websites have been shown to be potentially far reaching.

Personal Data and Privacy

In the light of both GDPR and Facebook’s privacy issues the development community around WordPress has been quick to respond with enhancements to increase its compliance with the requirements of GDPR. WordPress 4.9.6 was released 17th May was a minor update in version numbering but added a few new settings and controls in the WordPress backend to help with compliance, the following is quick overview of what has been added and what the intentions are behind them.

After updating to 4.9.6 you will see a popup highlighting the new “Personal Data Export and Erasure” features that have been added to the Tools menu, along with a new Privacy feature in the Settings menu.

Privacy Policy

Accessing the new Privacy feature in the Settings menu will show a general overview of why you may need to add a Privacy Policy page to your website. Whilst GDPR is currently the most prominent regulation which may affect the legal need for a privacy policy page there are also other regulations in place around the world.

You can then select an existing Privacy Policy page if you have one or you can click the “Create New Page” option which will add a new page to your site with suggested privacy policy content, which you can then edit. Some of this content is more broad generic privacy information but some such as the “Comments” section details information that may be held when users comment on your WordPress site. So even if you do not have users logging in to your website it is important to note that the process of simply leaving a comment on your website involves the person doing so to provide some personal information in this process and the saving of cookies in the user’s browser. Subsequently there is a new permission checkbox on comment forms to allow users to explicitly consent to this.

Export Personal Data

In the Tools menu there are two new features added to provide a way to manage the personal data of specific users’ data on your website. Regulations like GDPR require that users are able to request to see all of the data that your website may hold about that user, the new “Export Personal Data” function allows you to enter the email address of a user which will then email a link to a zip file of all of the data held relating to that email address.

Erase Personal Data

The second new addition to the Tools menu is the “Erase Personal Data” function. This provides a way for any identifying information related to a user to be erased from the site. It’s worth noting that this doesn’t delete actual comments from the site but it does remove any way for these to be identified either on the front-end or back-end of the website.

You enter the email address of the user requesting erasure of their personal data into the field and then this will send out an email to the user asking them to confirm the erasure of their data, so it puts the ultimate control of this data in the user’s hands.

Are you a plugin developer?

If you are a WordPress plugin developer then hopefully you haven’t been oblivious to these changes that have been happening in WordPress core, but if not then it’s worth taking a look at the update guide for WordPress 4.9.6 as there is some impact on plugin developers. Particularly if your plugin handles any personal user data then this may be extremely important for you to get up to speed on: https://make.wordpress.org/core/2018/05/17/4-9-6-update-guide/

You should also have a good read through the Privacy section of the Plugin handbook: https://developer.wordpress.org/plugins/privacy/

What next?

These tools in WordPress core are just the start of an increased focus on user privacy and data security within WordPress and the many plugins in the WordPress ecosystem. You can expect some further additions in future releases and in particular new features added to third-party plugins in the interest of data protection and privacy.

Instagram-api-ocalypse

If you use the standard “Instagram Platform API” for anything then it’s worth noting that planned deprecations have just been brought forward as of 5th April 2018. It seems like this is going to cause quite a few apps to break and result in a lot of unhappy developers:

To continuously improve Instagram users’ privacy and security, we are accelerating the deprecation of Instagram API Platform, making the following changes effective immediately. We understand that this may affect your business or services, and we appreciate your support in keeping our platform secure.

These capabilities will be disabled immediately (previously set for July 31, 2018 or December 11, 2018 deprecation). The following will be deprecated according to the timeline we shared previously:

Preston Watson – Dundee’s aviation pioneer

I was watching a documentary about the 100th centenary of the UK’s Royal Air Force today and in particular it looked at the early aircraft used in World War 1.

I was reminded that Dundee has a history of innovation in the early days of flight. Preston Albert Watson built and flew aircraft in and around Dundee, at times from a makeshift runway in Errol. There’s a lot of debate as to when he first flew, some records point to it happening prior to the Wright Brothers first powered flight, however this is largely held to be inaccurate.

Regardless though, Preston Watson is definitely another innovator from Dundee who should perhaps be a bit more widely known.

You can read a lot more about him on Wikipedia: https://en.m.wikipedia.org/wiki/Preston_Watson
