Link to notification settings on iOS

After iOS 16

Use openNotificationSettingsURLString, a constant in Swift for linking to your app's notification settings.

See the relevant Apple Developer documentation

Usage:

if #available(iOS 16.0, *) {
    return UIApplication.openNotificationSettingsURLString
}

After iOS 15.4

Use the deprecated constant UIApplicationOpenNotificationSettingsURLString.

if #available(iOS 15.4, *) {
    return UIApplicationOpenNotificationSettingsURLString
}

See the relevant Apple Developer documentation

Before iOS 15.4

Before iOS 15.4, you cannot link specifically to the notifications settings. Only to your app's settings page.

return UIApplication.openSettingsURLString
