            guard let settingsUrl = URL(string: UIApplication.openSettingsURLString) else {
                                                              ^~~~~~~~~~~~~~~~~~~~~

Changing UIApplication.openSettingsURLString to UIApplicationOpenSettingsURLString will fix your error.

Change it in /platforms/ios/AppName/Plugings/cordova-plugin-qrscanner/QRScanner.swift on line 471 and line 484.

Also, I needed to replace it in/cordova/plugins/cordova-plugin-qrscanner/src/ios, also on line 471 and line 484.

I've also had this issue. Changing the swift version of the project to 5 worked for me. Try https://www.npmjs.com/package/cordova-plugin-add-swift-support

I've added the plugin and put <preference name="UseSwiftLanguageVersion" value="5" /> into the ios section of my config.xml

The line did get copied to the config.xml inside the ios platform folder ... so it should be configured correctly. Unfortunatelly the error message remains the same. The setting somehow seems to be ignored.

Same problem of @chrsi , Error in Xcode :

testBarcode[41952:3157079] Error is [object Object]
Message from debugger: Terminated due to signal 15

Any Help

I could fix it this way:

In Xcode go to Build Settings -> "Swift Compiler - Lanuage" -> "Swift Lanuage Version" Set it to at least 4.2, then it works.

I am using Cordova 9 and cordova-ios 5.0.1

The right way to write the preference is:

<preference name="SwiftVersion" value="5" />`

otherwise it was not working for me. If you are using Cordova 9, try that :)
