Utilizing new `AppDelegate.swift` format in React Native 0.77

[MikeLikesCode]

Hey!

My team is upgrading to React Native 0.77 and we are migrating over to the new AppDelegate.swift file that the RN team shows in their template code. With that we had to migrate over from C to Swift for RN-Key-Command and came up with the following code.

class AppDelegate: ExAppDelegateWrapper {
...

  override var keyCommands: [UIKeyCommand]? {
    return HardwareShortcuts.sharedInstance().keyCommands() as? [UIKeyCommand]
  }

  func handleKeyCommand(_ keyCommand: UIKeyCommand) {
    HardwareShortcuts.sharedInstance().handleKeyCommand(keyCommand)
  }

}

After building this doesn't work and I was wondering if someone has come across this or if my implementation is wrong. Thanks!

The fix for using this in Swift involves a couple of steps. Create a bridging header file as outlined here:

https://developer.apple.com/documentation/swift/importing-objective-c-into-swift

In the bridging header file, add the import for HardwareShortcuts:

//  my-application-Bridging-Header.h
#import "HardwareShortcuts.h"

Then, in your AppDelegate.swift, add the following code:

  override var keyCommands: [UIKeyCommand]? {
    return HardwareShortcuts.sharedInstance().keyCommands() as? [UIKeyCommand]
  }

  @objc func handleKeyCommand(_ keyCommand: UIKeyCommand) {
    HardwareShortcuts.sharedInstance().handleKeyCommand(keyCommand)
  }
