The latest iOS version is here, and it is here with various eye-catching features that will take the iPhone mobiles to the next level. There has been a big update on the safari browser in which people are going crazy for. If you do not know about it, read this article as it will tell you about the link between Safari and the latest iOS 15 operating system.

The iOS 15 has added a toggle that will reverse the Safari design back to the iOS 14 design. When Apple initially announced and showed the coming iOS and macOS operating systems at WWDC, they showed a major redesign for Safari across the platforms. Apple has taken a step back regarding the controversial design with tweaks and user-accessible toggles.

Current Ios Safari Version Update

Though Apple creates products for its own operating system, it's also responsible for Safari, which is a web browser that works on Windows devices. Though previous versions suffered from a number of glitches and bugs, the latest version runs almost as smoothly as other browsers like Firefox.

The latest beta version shows that the newest iOS version has a toggle to Safari settings that will let you switch back to the old design language. With this version, you will be able to navigate through the Settings App, then go to Safari, and you will be given two options first on the top and second on the bottom. Both options will let you choose the design you prefer for Safari.

Pull to Reload

You can now go to the webpage set by simply tapping in the Aa, or you can just reload the page by tapping on the reload button. With the help of this interface, when a user scrolls through the webpage, the Tab Bar will collapse down so that the user can see more of the website.

The latest iOS 15 will now let you refresh the webpage with a downward swipe. It is a great alternative to having to tap on the reload icon. iOS 15 also has various other exciting features that we will all get to see.

What's new, what's missing, new challenges and new capabilities for iPhone and iPad

Not every minor iOS version update includes changes in the Web platform, but iOS 14.5 is an exception. It has a new version of the WebKit engine, changes in WKWebView, Safari 14.1 as the browser, and an updated engine for PWAs. It's also the first update in 2021 for Web and PWA developers since the release of iOS 14. And, as usual, as of today, there are no Safari release notes for this version.

This version's research reminded me of the first article of this series 10 years ago: a feeling with a mix between excitement and frustration after finding something new but completely undocumented. How should I call the series of iOS articles I've been doing so far? Some options: 'Safari on iOS: The missing documentation', 'The inflammatory* guide to Safari for Web professionals', 'Eternal sunshine of the documentation-less platform' 🤔

Anyway, iOS 14.5 is packed with new things you should know if you are a web developer, including some changes on the PWA platform.

Progressive Web Apps on iOS 14.5 #

After defining the idea in 2007 and supporting all the specs in 2018, Apple finally acknowledged the name 'Progressive Web App' and the platform as an alternative to the App Store. It's not how we all were expecting this to happen, but at least it's a start. No one from the WebKit and Safari teams is talking about PWAs; Apple's lawyers defined PWAs and their compatibility on iOS and iPadOS as evidence against App Store monopoly to the Australian Competition and Consumer Commission (ACCC) (see full PDF document). This declaration supports what I said earlier this year about why Apple kept the PWA platform as a minimal viable product.

Status Bar Change #

The first change that I've discovered for PWAs in 14.5 is the status bar. The status bar stopped rendering a white status bar as in 14.4. So I started researching the meta with the name apple-mobile-web-app-status-bar-style, and I've found something interesting. There are new values for this meta tag, never documented by Apple. But they are doing the trick on iOS 14.5, so if you are expecting a white status bar, you need to make a change.

The Apple documentation about this meta tag was last updated in 2014 and it's outdated. It's currently under the Documentation Archive) and there is no other document replacing it.

These are the current values accepted by the meta tag: light-content, dark-content, hidden, default, and it still takes two old values now marked as deprecated: black, and black-translucent. For some years, white was also accepted, but it was never documented. Now it's officially out.

If you want a white status bar, then you need to use the new value:

The value black-translucent is still the only way to simulate something similar to a display: fullscreen in the Web Manifest on iOS and iPadOS. It's marked as deprecated, but Apple never documented what's the replacement. Now that I've found the hidden value, I think that is the one that should be replacing it. However, it's not working, and while I can confirm the value is set in the Web Clip (the icon on the home screen), nothing happens differently than the default.

A white static status bar is not possible if the user has a dark appearance enabled unless you use black-translucent and a white document's background color.

Based on the appearance of the device (Light or Dark) and the value of the meta tag, the status bar of your PWA will follow the following pattern

B/W=Black over White, W/B=White over Black, W/T=White over Transparent (viewport takes fullscreen)

The new values make non-sense, and it seems they are shipping a half-baked implementation.

We have:

• A deprecated value black-translucent with no alternative value
• Three values with the same result (default, dark-content, hidden)
• One value light-content equivalent to the deprecated black value
• One value dark-content equivalent to the removed and never documented white value
• A hidden value that hides nothing
• If you don't provide a meta tag, the results are different than using default as a value

For some reason, the iOS simulator exposes different status bar colors than the ones I see on real devices

Nothing seems to make sense, but it is what it is 🤷‍♂️

What Is The Most Current Safari Version

I'm not sure if these new values appeared now or they've been hidden there for a while, but from iOS 14.5, the deprecated black value and the default values are changing, so the new undocumented but actual values appear as the only solution

What about theme-color? #

The Web App Manifest spec and the HTML Living Standard support the theme color, which is used by Android and desktop PWAs to tint the browser, the status bar, or the title bar. Safari was ignoring this value in the past. It's still missing it on Safari 14.1. However, there is good news: WebKit has added support for it, it's now part of the Manifest data structure, and WKWebView will have a themeColor property.

It's still unclear if Apple will use that property parsed by WebKit to style the PWAs and stop using the meta tag in the future; we'll need to wait some months until iOS 15 maybe or wait for the miracle of hearing something from the Safari team before that.

Background Audio #

After Web Push and a better installation prompt, background audio for PWAs is the following typical complaint. Well, still no luck. Background audio from a PWA continues playing in the iOS Simulator, but that's not the situation on an actual device. I presume it's because the process is suspended not matter if you are playing audio.

But there is one hope: the Media Session API is now available as an experiment (disabled by default). When your PWA was playing audio (or even video), the user can control the media playing from the Control Center and the notifications area. That means, shortly, this can be how Safari will allow PWAs to play audio in the background. We'll see!

Bugs and Missing Features #

Some old bugs are still there, such as seeing 'Untitled' in the status bar's back button when you open a link from a PWA. Another bug that I saw without consistency is that sometimes the service worker is not available when you are offline and open the app from the home screen.

Also, the missing features that a lot of people are waiting for are still pending, such as:
*PWAs in the App Library
*Web Push
*Background Sync
*Better Installation Flow (beforeinstallprompt or an App Banner)
*Ability for other browsers to install PWAs

Speech Recognition API #

Safari has supported Web Speech API partially for years (only the Speech Synthesis part). But now, the team has decided for some reason that eight years after Google Chrome started to support the Speech Recognition part of the spec, it was time for Safari to do the same.

From iOS and iPadOS 14.5, Safari and PWAs can recognize speech from the user using the microphone and an Apple cloud-based service. It works only after the user has started an interaction (such as a click handler), and it can recognize multiple languages.

Update 27/4: Unfortunately, the Speech Recognition API does NOT work inside a standalone PWA. The API is available, so a feature detection algorithm detects it, but nothing happens. My guess is that it has to do with the speech or microphone permission that is not working while in a PWA. Also, it has to do with Apple folks not testing within standalone apps, as usual.

Safari Newest Version

The Model HTML Element experiment #

WebKit now supports a new HTML element as an experimental feature that was never proposed or discussed in any standard or spec as far as I know.

The feature is disabled by default, and it represents a 3D Model that can potentially be rendered in virtual reality or augmented reality. The model element needs one or more <source> elements, presumably in different formats. However, it's available in the DOM but not working yet:

The code to render a 3D or AR model will look like

Right now, enabling the experiment does not render any model on the screen. The element is in the DOM using the new constructor HTMLModelElement, and the currentSrc property works, but nothing is rendered on the screen, so this seems like an experiment in the early stages

The model element will support a ready promise to know if the model could be loaded or not:

We need to remember the ability to render 3D/AR model was added to Safari 12 in 2018, but it is using a weird <a> element with a rel='ar'.

It's interesting to see Apple innovating again with the Web; it's also odd to see them implementing something that was not discussed anywhere before when they always complain that Chrome implements features that are not yet standardized.

Contact Picker API #

The Contact Picker API is now an official experiment (disabled by default) in Safari and PWAs. It let web apps pick a contact from a selector and get the value(s) as a JavaScript object. This API has been in Chrome for a year and a half, being one of the shortest periods between Chrome and Safari implementations in several years.

The properties available for query in this version of iOS/iPadOS:

• name
• email
• tel

The similar native component CNContactPickerViewController has more properties available, such as givenName, familyName, jobTitle, organizationName, postalAddress, socialProfiles that are not available from the Web platform at this time.

Android since version 83 also supports address and icon as available properties to query. The spec makes the list of properties dynamic so that every platform can pick the exposed properties. Do not query for unsupported properties, or you will get a TypeError exception.

Privacy-Preserving Ad Click Attribution #

Private Click Measurement (PCM), a new ability available in Safari from iOS 14.5, to track click conversion and link attribution for seven days is available. It's also the first time WebKit documented something new when shipping it in a beta version of iOS.

If you read the spec, the WebKit blog, the Safari settings, you will see different names for the same feature: 'Privacy Preserving Ad Click Attribution,' 'Private Click Measurement,' 'Privacy Preserving Ad Measurement.'

To use this feature, each link must include new attributes, and attribution will be sent over a well-known URLs. Two hundred fifty-six source IDs can be tracked with 16 different conversion events. Attribution data will be stored client-side for seven days and can be deleted or turned off by the user.

Read more about this spec in the WebKit blog.

The solution also includes a way for native apps on iOS to send click attribution for websites. (Not sure how that part can become standard as it is, though)

There is an experiment that can be enabled to help to debug the usage of this API: Private Click Measurement Debug Mode

Paint Timing API #

The Paint Timing API is out of the experiment, and it's now enabled by default. It let us query about only one web performance metric: First Contentful Paint (name equals to first-contentful-paint).
