I installed mapbox into my xcode project using cocoapods.

Then I just copied and pasted the example for creating a custom user location annotation into my view controller.

I get the following errors over and over again.

2019-04-20 21:40:17.546153-0600 MapboxExample[17175:6272371] TIC Read Status [3:0x0]: 1:57

They seem to happen when I zoom in and out of the map, or sometimes when I move the map.

Code

The only swift files are ViewController.swift, which copied from the mapbox website exactly

and AppDelegate.swift, which was created automatically(I've remove the comments from the AppDelegate).

import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
    var window: UIWindow?
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {return true}
    func applicationWillResignActive(_ application: UIApplication) {}
    func applicationDidEnterBackground(_ application: UIApplication) {}
    func applicationWillEnterForeground(_ application: UIApplication){}
    func applicationDidBecomeActive(_ application: UIApplication) {}
    func applicationWillTerminate(_ application: UIApplication) {}
}

  • I get these all the time. When I originally encountered them I dug around and (I think) I discovered they were simply download commands that were cancelled by the API during zooming, etc. Say you zoom with a slight bias/movement to the right then tiles being downloaded for the left might get cancelled. That cancellation is being reported in the error code which seems a little verbose to me. I treat it as a return code rather than an error code. Unfortunately when I did a quick search just now for my source I couldn’t find it. I’ll try again later when I have more time. – Magnas Apr 21 '19 at 05:43
  • @Magnas Any luck? What do you mean by return code? Do you actually code something to handle it differently? To me it's just a message that appears in my console so I'm not quite sure how to do that. – Sam Apr 24 '19 at 08:06
  • Hib @Jacob - Sorry for the delay. By return code I simply mean a response from the server that isn't an actual error. For example the familiar 200/201 codes that indicate success. I'd assumed they were all just being supplied under the 'error' banner whether benign or not. Anyway, I did find a couple of related things for the -999 code and it seems I was only partially correct. -999 appears to be a URLErrorCancelled code of the URLSessionTask. I'll post the links here so you can read for yourself. I don't handle them in any special way beyond ignoring them. – Magnas Apr 24 '19 at 14:03
  • https://pspdfkit.com/guides/ios/current/pspdfkit-instant/error-999/ and https://stackoverflow.com/questions/16073519/nsurlerrordomain-error-code-999-in-ios/16076142 – Magnas Apr 24 '19 at 14:04
  • @Magnas Do you know a way to squelch the warning at least? I noticed the second link has an objective C answer as the second answer on the question, do you know what that translates to in Swift? – Sam Apr 24 '19 at 21:56
  • @Magnas Also, are the TIC read status and boringSSL 8196 errors part of the same problem or are they something different? Do you know anything about those? – Sam Apr 24 '19 at 21:56
  • There is a good explanation for the TIC message here: https://stackoverflow.com/questions/46352735/what-is-tic-read-status-157-in-ios11-xcode-9 which basically (again) recommends ignoring it. As for the Objective-C answer, I'm sorry I can't help. It looks like something specific to the OC's question about Facebook/Corona. – Magnas Apr 25 '19 at 14:51
  • @Magnas and is the boringSSL error also something to be ignored – Sam Apr 26 '19 at 00:24
