URL sharing doesn't work on iOS 18

[darix795]

Describe the bug Yesterday I upgraded Xcode to version 16 and try to run my app on iOS 18, but seems that when I share urls to my app controller is showed but app isn't opened. When I try on simulator with iOS 17 everything works fine.

To Reproduce Try on iOS 18 and that's it

:/ any error in console or xcode logs ?

This is likely due to this function: https://github.com/achorein/expo-share-intent/blob/1c41e641bc1e6c91999d10ba63477ab9f254430f/plugin/src/ios/ShareExtensionViewController.swift#L251-L269

In line 254, you're using an openURL selector on UIResponder. This has been deprecated for quite a while (past iOS 10) and has now been completely disabled in the iOS 18 SDK:

• https://developer.apple.com/documentation/uikit/uiapplication/1622961-openurl
• https://developer.apple.com/documentation/ios-ipados-release-notes/ios-ipados-18-release-notes#UIApplication

However, it's not as simple as changing the selector in line 254 to i.e. open:options:completionHandler:. Here's a write-up on a similar issue in the KeyboardKit SwiftUI SDK (unrelated package, but the issue is effectively the same).

Unfortunately, I currently don't have the time to propose a fix, but just wanted to leave this here in case it helps. For now, you'll need to build with the iOS 17 SDK / Xcode 15. If you do, the share extension will work fine in iOS 18, too. Currently, the Expo EAS cloud still uses Xcode 15, therefore it works fine if you build the app using EAS Cloud (once they switch to Xcode 16 / iOS 18 SDK, you might be able to force the old Xcode / SDK by using the macos-sonoma-14.5-xcode-15.4 server image).

getting this same error when sharing an image, probably related.

I will check xcode16 and ios18 issues next week.

Ok, i tried to reproduce error in this repo and I solved by replacing SLComposeServiceViewController extension to UIViewController and application.perform(selectorOpenURL, with: url) with application.open(url) in according with Apple's offical docs.

- class ShareViewController: SLComposeServiceViewController
+ class ShareViewController: UIViewController

- let selectorOpenURL = sel_registerName("openURL:")

- application.perform(selectorOpenURL, with: url) 
+ application.open(url)

After this changes it seems to works fine on Xcode 16 and iOS 18. I was tested with links, files and images. Unfortunately, i haven't permission to open new pull requests.
