I'm trying to complete the "Build a Mobile Insurance App with Swift and the Salesforce Mobile SDK for iOS" trailhead but I'm stuck. I've installed the package in my Trailhead Playground, and created the XCode project from the repository link. I refactored the NewClaimViewController+Uploading.swift file like they say to to call uploadPhotos and uploadAudio asynchronously (code pasted in comment) and added my playground domain to the app login. When I log into the app from the simulator, i get the message "Server Error Can't connect to the server: An SSL error has occurred and a secure connection to the server cannot be made." If I click OK, it moves forward with the sign in but the Claims landing screen loader spins endlessly. I can click the plus sign to make a claim, but again when I hit submit, again I get an endless spinner and the record is not created in the playground.

Hello All,
I am trying to Create a Hello World Lightning Web Component as mentioned in the URL below.
Hello World Lightning Web Component (https://trailhead.salesforce.com/content/learn/projects/quick-start-lightning-web-components/create-a-hello-world-lightning-web-component?trail_id=build-lightning-web-components)
But in VS code I am getting below output and did some analysis but unable to risolve it please help me how can I proceed further.

VS code output:
Starting SFDX: Authorize an Org

09:42:18.175 sfdx force:auth:web:login --setalias vscodeOrg --instanceurl https://login.salesforce.com --setdefaultusername
ERROR running force:auth:web:login:  Cannot start the OAuth redirect server on port PortInUseAction. 

Try this: 
Kill the process running on port 1717 or use a custom connected app and update OauthLocalPort in the sfdx-project.json file.
09:42:23.367 sfdx force:auth:web:login --setalias vscodeOrg --instanceurl https://login.salesforce.com --setdefaultusername ended with exit code 1
------------------------------Sometimes below error is coming-------------------
use a custom connected app and update OauthLocalPort in the sfdx-project.json file

Thanks in Advance :)

I'm stuck on step #2 of Einstein Analytics and Discovery Insights Specialist superbadge.  I'm getting this warning while checking the challenge:

The step "Churn Tenure' is in compact form, so the filter values need to be specifed as a minimum and maximum
The static step that feeds has the following the value:
 

"Tenure_Length": {
                "broadcastFacet": false,
                "label": "Tenure Length",
                "selectMode": "single",
                "type": "staticflex",
                "values": [
                    {
                        "display": "High Risk",
                        "value": "1 to 12 months",
                        "min": 1,
                        "max": 12
                    },
                    ...
                ]
            }

I'm using selection binding for min and max values.  The dashboard is correctly filtering:


Any ideas? 
I've tried a non-compact form step where I inject a saql fragment into the query, as well as where I inject min/max values using a range filter serialization...All these efforts end in the same challenge failure message.

Any help/suggesitions are welcome!

I can't progress pass the first stage on this project.  I get the error: Could not authenticate with the IBM Bluemix service. Please validate your credentials (also below).  Please can anyone help?
