Changing Badge Notification count with Pushy in Capacitor/Cordova on iOS - swift

Question

I have a Capacitor/Cordova app using Pushy (https://pushy.me) to handle push notifications. Sending push notifications to devices seems to work fine, and as part of that transaction I can set the app's notification count on the icon when the app is closed.
However, Pushy only seems to have an JS option to clear the counter Pushy.clearBadge(); rather than change it to a specific number from within the app when it's running. The scenario being if a user has read one message, but leaves two unread and then closes the app, I want the counter to be correct.
Digging through the PushyPlugin.swift code, the function for Pushy.clearBadge(); looks like this:
#objc(clearBadge:)
func clearBadge(command: CDVInvokedUrlCommand) {
// Clear app badge
UIApplication.shared.applicationIconBadgeNumber = 0;
// Always success
self.commandDelegate!.send(
CDVPluginResult(
status: CDVCommandStatus_OK
),
callbackId: command.callbackId
)
}
Which is tantalisingly close to giving me what I need, if only I could pass an integer other than zero in that line UIApplication.shared.applicationIconBadgeNumber = 0;
My knowledge of Swift is zilch, other than recognising familiar programming syntax. I thought I'd have a hack at it and tried adding this to the PushyPlugin.swift file:
#objc(setBadge:)
func setBadge(command: CDVInvokedUrlCommand) {
// Clear app badge
UIApplication.shared.applicationIconBadgeNumber = 100;
// Always success
self.commandDelegate!.send(
CDVPluginResult(
status: CDVCommandStatus_OK
),
callbackId: command.callbackId
)
}
But the app coughed up Pushy.setBadge is not a function when I tried to give that a spin (note, I was testing with 100 just to see what would happen, ideally I'd want to pass an integer to that newly hacked in function).
So what I've learnt so far is I know nothing about Swift.
Am I sort of on the right lines with this, or is there a better way to set the badge counter?

Answer 1

Ok, so I spotted in the pushy-cordova/www folder a Pushy.js file which I needed to add my new function to
{
name: 'setBadge',
noError: true,
noCallback: true,
platforms: ['ios']
},
Then, a bit of trial and error with the PushyPlugin.swift function I added to this:
#objc(setBadge:)
func setBadge(command: CDVInvokedUrlCommand) {
UIApplication.shared.applicationIconBadgeNumber = command.arguments[0] as! Int;
// Always success
self.commandDelegate!.send(
CDVPluginResult(
status: CDVCommandStatus_OK
),
callbackId: command.callbackId
)
}
Then this can be called in my Capacitor project with Pushy.setBadge(X); (X being the int value you want to display on your icon).
