I’m having the same issue.
Im using Unity 2021.3.17 and using Application.OpenURL(url); to open a webpage.
When I run the project through Xcode 15.4 it works fine.
If I run it through Xcode 16.2, it does work and I get the error message:
BUG IN CLIENT OF UIKIT: The caller of UIApplication.openURL(: ) needs to migrate to the non-deprecated UIApplication.open(:options:completionHandler:). Force returning false (NO).
If Application.OpenURL is depreciated, is there another code I could use instead?
Ideally, I don’t want to update my Unity project because that usually creates more issues than it fixes, especially when I’m on a project deadline.
I updated my MacBook to Sequoia recently so I can’t install Xcode 15.4 on it.
