Hello Apple Developer Community,

I'm experiencing an issue with PDF link interaction in WKWebView that appears to be specific to iOS 26.

Problem Description:

I'm loading a PDF in WKWebView.The links may vary widely and are not necessarily DPF, so I need to load them using WKWebView. On iOS versions prior to 26, links within the PDF are clickable and work correctly. On iOS 26, the same links are not clickable (no response when tapped). Expected Behavior:

PDF links should remain clickable and functional across all iOS versions.

What I've Tried:

Tested opening the PDF directly in Safari on iOS 26 - links still not clickable This suggests the issue might be related to changes in the system's PDF rendering engine Reproduction Steps:

Load the PDF URL in WKWebView Navigate to page 12 Attempt to tap the link Environment:

Test Devices: iPhone 15(26.0 ) / iPhone 16 Pro Max(18.0.1 ) Xcode: 16.2

Questions:

Is this an intentional change in iOS 26's PDF handling or WKWebView? If so, is there a new API or configuration to restore link interactivity?

Any guidance or suggestions would be greatly appreciated!

Hello @kirito_song! Could you share which PDF file you are reproducing this with? And, how is your WKWebView configured?

For reference, I just spun up a bare WKWebView and was able to do in-document link navigations on https://help.apple.com/pdf/security/en_US/apple-platform-security-guide.pdf.
