Hi All,

I'm checking out an ArcGIS Runtime license from our ArcGIS Online account using the code below that is copied from ArcGIS Runtime SDK for iOS documentation:

//get the users license info from the portal

portal.fetchLicenseInfo { (licenseInfo,error) in

    guard let error = error {

        print("Error fetching user's licenses... \(error)")

        return

    }

    //set the license using the Named User's licenseInfo

    do {

        let result = try AGSArcGISRuntimeEnvironment.setLicenseInfo(licenseInfo!)

    } catch let error as NSError {

        print("error: \(error.localizedDescription)")

    }

    //The app is now licensed

    // Save the license information so that the app can be started and licensed offline

    // In this example the licenseDictionary is stored in keychain

    var licenseDictionary: NSDictionary?

    do {

        licenseDictionary = try licenseInfo?.toJSON() as! NSDictionary?

    } catch {

        print("LicenseInfo not available")

    }

    let keychainItem = AGSKeychainItem(identifier: "com.your_org.your_app_name", accessGroup: nil, acrossDevices: false)

    keychainItem.writeObject(toKeychain: licenseDictionary!, completion: { (writeError) in

        if let error = writeError {

            print("Error writing to the Keychain... \(error)")

        }

    })

 

The problem is that the completion closure of the portal.fetchLicenseInfo() method never gets invoked and as a result I never get a license or an error...

However, I can get a valid license from the portal property: portal.portalInfo?.licenseInfo, but 'licenseInfo' is deprecated: This property has been replaced by `AGSPortal#fetchLicenseInfoWithCompletion:` from Xcode.

Does anybody have any idea please? I'm using SDK 100.10.

Thanks,

Shimin

Are you holding on to the `portal` instance? If it gets deallocated before the round trip to the server, then the completion handler won't get called. Can you make it an instance variable?

Thanks Nick for your reply. I don't think the portal variable is deallocated because I can get a valid license from portal.portalInfo.licenseInfo. I'll try to make it an instance variable...

Hi Nick,

Making it an instance variable helped. Thank you so much for your help.

Cheers,
