Ask HN: React Native or Swift for iOS app?

[ud0]

So I'm building a mobile app whose core feature is scanning QRcodes. I notice how effective the WhatsApp on iPhone scans QRcode even in low light conditions. I want that kind of efficiency in my app because it's the most important feature. Can ReactNative provide this or do I have to go with Swift?

Either way, if you're adventure enough, try SCADE beta release that will run on Android and iOS natively using Swift langauge. To check SCADE out, http://scade.io and they are working with PerfectlySoft who doing Server-side Swift Perfect.ly

You don't have to do this in Swift necessarily, you can go with ReactNative. Please look at this: https://github.com/moaazsidat/react-native-qrcode-scanner
