Apple has confirmed that it is aware of an issue causing web links to crash in multiple iOS apps like Safari, Mail, and Messages, reports TechCrunch. Following multiple complaints about the bug over the past few days, Apple says it is working on a fix that will be released "soon" via a software update.
Shortly after the release of iOS 9.3, iPhone and iPad users began complaining about a bug that causes multiple built-in and third-party apps to crash or freeze after a web link is tapped or pressed using a long press. The issue does not affect all users, but based on threads in the MacRumors forums and the Apple Support Communities, it is impacting a wide range of iOS users and a long list of iOS devices including the iPhone 5, 5s, 6, 6 Plus, 6s, 6s Plus, iPad Air 2, and iPad min
The specific cause for the issue is still unconfirmed, but there is speculation that it is related to Apple's Universal Links feature. According to mobile specialist Ben Collier, the Shared Web Credentials daemon, which allows apps and websites to share login credentials for Universal Linking purposes, may be a factor.
Apps with large deep linking files for use with Universal Linking could also be causing the problem, as many users who had installed the Booking.com app have experienced crashing and freezing issues. The Booking.com app, though now fixed, was originally using an overly large 2.3MB deep linking file.
The web links fix may be bundled into iOS 9.3.1, which Apple is already working on. Over the last few days, we've seen an increasing number of visits from devices running iOS 9.3.1, suggesting Apple has sped up testing on the update.
The web linking bug is the second major bug to affect iOS 9.3 users. The first rendered some older devices unusable due to a problem with Activation Lock, which required customers to enter the information originally used to set up their iPhone or iPad. Apple issued a new version of iOS 9.3 on Monday to fix the issue.
