The parameter needs to be of type Timer. I.e.
@objc func pidsUsage(timer : Timer) {
}

In the timer's `.userInfo` property? – Guy Kogus May 15 '18 at 14:27

po sender.userInfo![0] . getting this while reading userinfo.. error:
:3:16: error: type 'Any' has no subscript members sender.userInfo![0] – djt May 15 '18 at 14:51 -
You'd need to cast it. `(timer.userInfo as! [Int])[0]` – Guy Kogus May 15 '18 at 19:14

thanks... I do it this way, let userInfo = sender.userInfo as! Dictionary

The more "Swift" way to write that would be `as! [String: AnyObject]`. And `AnyObject` is usually used for converting between Objective-C and Swift, so even better would be to use `[String: Any]`. – Guy Kogus May 16 '18 at 06:05
