Cannot build iOS app - 'openSettingsURLString' has been renamed to 'UIApplicationOpenSettingsURLString'

[adamayoung]

I cannot build an iOS app with this plugin. I get the following errors:

                                                   ^

Yes, it's an known issue. Change UIApplication.openSettingsURLString to UIApplicationOpenSettingsURLString

[adamayoung]

Are you planning on fixing this in a new release anytime soon? Making the above change isn't going to help when I do a CI build of the app.

[jamesopppp]

Same question

Yes, it's an known issue. Change UIApplication.openSettingsURLString to UIApplicationOpenSettingsURLString

You can workaround this issue by typing next command in the root of the project:
find . -type f -name "*.swift" -print0 | xargs -0 sed -i '' -e 's/UIApplication.openSettingsURLString/UIApplicationOpenSettingsURLString/g'

Yes, there is several pull requests to fix it like 106abbd . We only wait that it is approved, merged and released by creator. You can fork and doing it

I have given up on waiting for this to be fixed. I have created a substitute for the npm package using @markterrill code (Refer #271). If you want to try it run:

npm uninstall cordova-plugin-qrscanner
npm install git+https://git@github.com/danielzen/cordova-plugin-qrscanner

Hope it works for you...

[markterrill]

Cheers @danielzen !

Thanks for the reminder re npm install from git, that'll be very helpful to a lot of folk reading this thread.

Now that I have updated to Swift 5, I understand why @markterrill's code was not accepted. Perhaps it is better to set swift5 in Cordova or Capacitor (as I did)?

In cordova use: https://www.npmjs.com/package/cordova-plugin-add-swift-support

In capacitor set cordovaSwiftVersion: https://capacitor.ionicframework.com/docs/basics/configuring-your-app/

I'm leaving my Swift 3 version at https://github.com/danielzen/cordova-plugin-qrscanner in the meantime, but I no longer recommend it. Hope this helps.

srsly it has been almost a year now !

[terryjiang2020]

Is this closed because it is fixed?

[danielzen]

I recommend looking at:

• https://www.npmjs.com/package/cordova-plugin-qrscanner-11

based on

• https://github.com/v1934/cordova-plugin-qrscanner-11

It has updates that are working for me....

@terryjiang2020 - closed because there is nothing to fix - it is not a bug - your Cordova iOS settings need to use Swift 5 (at least 4.2, but definitely not 3) and the plugin will work fine.
See @danielzen's comment above on May 18, 2020 - also, see my comment from July 2021 on this similar issue for more help/details <-- I believe this holds the answer you are looking for.

I'm assuming you have an older project, so you probably need an older fix - this was the solution nearly 2 years ago.
But @danielzen's recent comment on April 14 may offer something more current (but I suspect he's using Swift 5 now, so hence how it works for him - just guessing). I still maintain that a "fix" to the plugin was never needed - just update your project's Swift version (under Cordova settings for iOS), and the newer qrscanner plugin should just work.
