iOS 10 app fails to register

[triceam]

I have an app that works fine on iOS 9, but when running on iOS 10 (beta) in the simulator, I get the following error.

Inside of my DJISDKManagerDelegate instance, the sdkManagerDidRegisterAppWithError fails with the following message:

Attempt to copy metadata from another registered device is not permitted.(code:-4)

This is occurring in the following code (in the error handler):

extension ViewController : DJISDKManagerDelegate
{
    func sdkManagerDidRegisterAppWithError(error: NSError?) {

        guard error == nil  else {
            debug("Error:\(error!.localizedDescription)")
            return
        }

        debug("Registered, awaiting connection...")
        #if arch(i386) || arch(x86_64) ||
            //Simulator
            DJISDKManager.enterDebugModeWithDebugId("192.168.1.15")
        #else
            //Device
            DJISDKManager.startConnectionToProduct()

        #endif

    }

Note: This is on the iOS simulator, using the DJI Bridge app to a Phantom 3. This exact configuration works fine if I target the iOS 9 simulator. I have not tested on-device yet b/c I don't want to upgrade my iPade to iOS 10 yet.

This is happening using Xcode 8 Beta 5.
Aircraft: Phantom 3 Advance
Firmware: The latest - I don't see a way to access the firmware version, but the DJI Go app is not prompting me to update.
SDK: Version 3.2, from this release snapshot: https://github.com/dji-sdk/Mobile-SDK-iOS/releases/tag/v3.2

Hi @triceam, this error is related to the app registration issue, please try the following methods:

1. Delete the apps on you iOS9 and iOS10 simulator and try again.
2. Modify your Xcode project's bundle ID and apply for a new App Key from DJI developer website, then try again.

Try if these two methods work, let me know the result. Thanks!

I tried both of these things, but neither fixed it:

1. I used "Reset Content & Settings" on the simulator to erase everything from it, but the problem did not go away. I received the exact same error message when I launched the app on the freshly cleaned simulator.
2. I'm not able to test this right now... Looks like the DJI developer site is having problems. None of my apps are showing up, and it won't let me create a new one. I opened up the debug console in Chrome, and it looks like someone left a reference to a localhost dev environment (127.0.0.1) in the deployed app code (see screenshot below).

Hi, please try to create a new app key on DJI Developer Website, it should work now. Thanks!

I'm still seeing errors on the DJI Developer website. I emptied the cache and reloaded, but I get the same error mentioned above (references to 127.0.0.1:3000).

Sorry for the inconvenience, please try again, it should work now.

Created a new ID, and changed my bundle identifier, but no luck - I got the same error message. iOS 10 is much more strict on networking & App Transport Security settings... possibly, do we need to add specific DJI domains or IPs to exception domains?

Hi, since we use NSUserDefaults in SDK registration, and Xcode 8 Beta 1 has a bug related to NSUserDefault, please try to reboot your Mac and run iOS 10 simulator directly or upgrade your Xcode 8 to Beta2.

Hope this help, thanks!
