// The trick is to link the DeviceSupport folder from the beta to the stable version.
// sudo needed if you run the Mac App Store version. Always download the dmg instead... you'll thank me later :)

// Xcode 10.2 to Xcode 11 Beta
sudo ln -s /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/13.0 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

// Then restart Xcode and reconnect your devices. You will need to do that for every beta of future iOS versions

JavaScriptCore is a built-in iOS library that enables you to use JavaScript in apps alongside Objective-C and Swift. It lets developers read JavaScript from a string, execute it from Objective-C or Swift, and share data structures and functions across languages. We JavaScriptCore to share code between Web and iOS.

Sharing code helped us produce a high-quality, consistent experience across devices while iterating rapidly.

This post is about why we chose to use JavaScriptCore and what we learned. The biggest challenges to using JavaScriptCore in a production app were performance optimization for older devices and getting the build process right. Luckily, these problems have simple solutions that just weren't documented.

Why did we use JavaScriptCore?

A killer feature of one of our apps is search that is optimized for finding guests by name. Our goals included:
