Touch Input Offset and Unresponsive Elements in iOS 18.6 (Xcode 16.4)

PLATFORM AND VERSION iOS Development environment: Xcode 16.4, macOS 15.6 Run-time configuration: iOS 18.6

DESCRIPTION OF PROBLEM Hi,

We recently noticed some issues when running our existing app, even after applying updates, on iOS 18.6. The problem occurs both on the Xcode simulator and on clients’ mobile devices running iOS 18.5 or later. However, devices running versions below 18.5, such as iOS 18.4 (including iPads), do not experience this issue.

The issue we are experiencing is that when we touch certain elements, they do not respond unless we tap slightly higher than the intended point. Please see the video in the link below. I believe others are also experiencing similar touch-related issues, though not identical to ours.

On iOS 18.4: Works as expected.

On iOS 18.6: The range bar cannot be moved unless we tap slightly above it, and once the map is displayed, the toggle button becomes non-functional.

This behaviour is not present in any earlier iOS version.

I suspect something may have changed in the OS that is causing this issue, possibly related to plugins, or perhaps something in Xcode that needs to be updated. We would greatly appreciate your guidance in resolving this matter.

STEPS TO REPRODUCE Please see the following videos 18.4, performing as expected.

18.6, with issues https://screenrec.com/share/MR4VpyIBks 18.6 with the issue

In addition to this. I have created a case on Code-level support, but i have not heard anything back

Have you raised a Feedback report? If not, please do so at https://feedbackassistant.apple.com/ then post the FB number here.

@darkpaw What is the purpose of the feedback report?

You have posted a bug report to the Developer Forums. The Developer Forums are for developers from all over the world to ask for hints and tips on coding their apps for Apple platforms. They are not a direct link to Apple's developer employees.

the usual way to report an issue to Apple is via the Feedback Assistant, so that they're aware of it. Posting a thread on these forums is not going to get your issue logged, triaged, and ultimately fixed unless you make Apple aware of the issue via the Feedback Assistant.

That's the purpose.
