Hi guys,

Little question for iOS 18 to open setting we need to use
https://developer.apple.com/documentation/uikit/uiapplication/1648685-open
UIApplication.sharedApplication().open(_:options:completionHandler:) instead of UIApplication.sharedApplication().openURL(nsUrl)

Does anyone encounter that issue? Not sure to understand how Platform is updated… Quite a blocking point

[Dmitry Stakhov]

Is this related to Compose?

[Sofiane Abbar]

I guess so @Dmitry Stakhov, I am using in it in Platform.ios.kt
UIApplication.sharedApplication().openURL(nsUrl) in a kotlin file, but it is not compatible with ios 18.

You know for the bridge with actual/expect.

internal actual fun navigateToDeviceFeatures() {
val nsUrl = NSURL.URLWithString(UIApplicationOpenSettingsURLString)

val success = UIApplication.sharedApplication().openURL(nsUrl)
    if (!success) {
        println("Failed to open URL: $nsUrl")
    }
}

This is related to compose, my question is who is responsible of that import Platform.UIApplication
UIApplication.sharedApplication().open(_optionscompletionHandler:) can’t be found

[Dmitry Stakhov]

Could you please mention the Compose API you try to use?
UIApplication is a native component and a part of UIKit

[Sofiane Abbar]

Yes but the UIApplication from the import Platform.UIApplication is a “binding` from Kotlin right?
.open() is missing while openUrl() is available

[Dmitry Stakhov]

> import Platform.UIApplication is a “binding` from Kotlin right
No, It's built from ObjectiveC using Cinterop tool that supports calling ObjectiveC code from Kotlin.
So basically Kotlin just provides you the API that Apple has added to their iOS SDK

[Sofiane Abbar]

Thanks a lot for this precious information @Dmitry Stakhov
Is there a way to re-run that Cinterop tool to have the API updated from iOS SDK?

[Dmitry Stakhov]

I guess just sync the project. Do you have the XCode 16 installed and xcode build tools set up correctly?
To confirm you have the correct Xcode setup you can run the xcodeVersion Gradle task from your KMP project to check Kotlin has detected to Xcode build tools with the right version.
If everything is ok run commonizeNativeDistribution Gradle task to regenerate Kotlin functions to call iOS SDK.

Also for similar questions please reach to the #C3PQML5NU or #C3SGXARS6 channel

[Sofiane Abbar]

Yes I have xCode 16 and trying on the newest iphone got some imcompatibilty, I will search about that commonizeNativeDistribution that i dont really have in Gradle.
Thanks for the advices

I also use same as u before ios18. so what should we do? need if else to check up if ok or not?

[Vaizin Nikita]

The function name is not the same in objC and swift. The swift is named open() but you should use the openURL() function. The change you must do is add a completionHandler parameter that is now required in ios18

[Sofiane Abbar]

Oh thanks @Vaizin Nikita I will check it out! And let you know… didn’t know function name are different between objectiveC and Swift…

[Sofiane Abbar]

Yes that works, thanks a lot @Vaizin Nikita
