What is a good way to open a web url in an external browser for iOS with compose multiplatform?

Tried `UIApplication.sharedApplication.openURL(NSURL(string = url))`but it prints

[Application] 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).

Also got the same result from LocalUrlHandler.current.openUri(url).

I tried what's written in the error message, but that function doesn't seem to be defined. Or I don't know how to write it - I come from an Android compose background..

I also tried directly adding the 1.7.2 version of androidx.compose.ui but gradle sync barfed - looks like a version conflict..

Oh. The error message is wrong too.

I had to call a different overload of the same method name like this:

UIApplication.sharedApplication.openURL(NSURL(string = url), options = mapOf<Any?, Any?>()) {
    if (!it) {
      println("Failed to open URL: $url")
    }
  }

Too bad the LocalUriHandler way is broken. The bug was reported but closed as a duplicate of the other different bug.

have you tried what the error suggests and using UIApplication.shared.open(url, options: [:], completionHandler: nil) rather than openURL?

Why do you think the other bug is different from yours? To me they look indeed identical.

I had this problem last week. While this bug is not solved, I decided to use this library for a while in my project

LocalUrlHandler.current.openUri(url). is calling the deprecated signature of openURL. But the bug linked as a duplicate is that the deprecated version no longer works.- which is not even a bug.

[Paul Wisner]

UIApplication.shared.open doesn't exist in compose multiplatform. (Or I don't know how to make the reference resolve.)

Anyway, it seems to be fixed in 1.7.0-rc01 now. https://github.com/JetBrains/compose-multiplatform/releases/tag/v1.7.0-rc01
