ios - How to detect whether custom keyboard is activated from the keyboard's container app?

Question

I was wondering if there is a method that would allow me to detect from the keyboard container app whether the associated keyboard has been activated in the the device's Settings app.

For example, I am interested in adding a simple "steps" feature inside the container app where step 1 would be "activate the keyboard", and step 2 would be contingent on step 1's completion. As such, I am interested in figuring out whether there is a way to detect whether the keyboard extension is activated?

Thanks!

Here is a method I have used in one of my projects. I think it is what you asked for, hope it helps you.

- (BOOL)isCustomKeyboardEnabled {
    NSString *bundleID = @"com.company.app.customkeyboard"; // Replace this string with your custom keyboard's bundle ID
    NSArray *keyboards = [[[NSUserDefaults standardUserDefaults] dictionaryRepresentation] objectForKey:@"AppleKeyboards"]; // Array of all active keyboards
    for (NSString *keyboard in keyboards) {
        if ([keyboard isEqualToString:bundleID])
            return YES;
    }

    return NO;
}
