# multiplatform

Hi all, I am currently facing an issue with opening app deeplinks from a Compose Multiplatform app when running on iOS. Maybe someone here has an idea...

The app is written in Compose Multiplatform and compiles for Android and iOS targets. I am trying to open another app on the device via an app scheme (<other-app://test>).

The deeplink opens the other app seamlessly in Android but on iOS opening the app fails without an error. When opening a webpage with the same mechanism, the browser opens, though. And when opening from a native iOS App, this works as well.

This is the file App.ios.kt I am using to implement the native code:

@Composable
actual fun getContextProvider(): ContextProvider {
    return object : ContextProvider {
        override fun launchIntent(url: String) {
            val nsUrl = NSURL.URLWithString(url)
            if (nsUrl == null) {
                println("invalid url: $url")
                return
            }
            val canOpen = UIApplication.sharedApplication.canOpenURL(nsUrl)
            if (canOpen) UIApplication.sharedApplication.openURL(nsUrl, options = emptyMap<Any?, Any>(), completionHandler = null)
            else println("Can not open url")
        }
    }
}

The canOpen check returns true but still the app is not opened...

All hints welcome!

TLDR: App scheme deeplink does not open on CMP for iOS

Check on the Xcode App output logs, sometimes, there is a reason printed

Thanks @François, indeed there was some info in there... The solution is to skip the part where I check for canOpen and just open it directly... 🎉
