Runtime 10.2.5 apps crashed in ios11 under device debug mode

[ShengchuanZhou]

Hi,

I updated my device and toolchains to ios11 and xcode 9 recently, and I found a crash issue in device debug mode which means the app can successfully run in simulator and release mode on the device, but will crash when i use debug mode on device.

The app will crash after invoke addMapLayer() method of a AGSMapView class, and there's no valuable information in the debug stack except one line :

Thread 1: EXC_BAD_ACCESS (code=2, address=0x197f5b2a8)

I believe it could be a threading problem in runtime 10.2.5. I tried to make a sample demo that only contains a few lines of code that only load a web map or a local tiled layer in a single-view app, and the crash issue is still there.

It would be good if someone can help me check the problem to make sure if it is a bug in runtime 10.2.5, and I also would like to know if ESRI will release a update to the runtime 10.2.5 to fix it.

Thanks.

Is there a stack trace? If you type "bt" in the console when it crashes, does it give you a stack trace?

thanks

Hi Ryan,

Thanks for your reply. I use xcode 9 and swift 4.0, and here are the stack trace information of my app:

The tested code is quite simple, the application crashed when i connect an 12-inch iPad pro then build and run the application in debug mode. The code of the viewcontroller are listed as follow:

import UIKit

import ArcGIS

class ViewController: UIViewController {

    @IBOutlet weak var mapView: AGSMapView!

    override func viewDidLoad() {

        super.viewDidLoad()

        let url = NSURL(string: "http://services.arcgisonline.com/ArcGIS/rest/services/Canvas/World_Light_Gray_Base/MapServer")

        let tiledLayer = AGSTiledMapServiceLayer(url: url! as URL)

        self.mapView.addMapLayer(tiledLayer, withName: "Basemap Tiled Layer")

    }

    override func didReceiveMemoryWarning() {

        super.didReceiveMemoryWarning()

        // Dispose of any resources that can be recreated.

    }

}

Hello Ryan,

I tested another program which is more complicated, and the crash issue occurs in the same line. The stack information is here:

It would be great if you can test the APIs. The application runs normally in simulator and release mode on the device. And there's no problem when i use ios10. 

Thanks.
