"Your Apex code contains field level access checks that are redundant now that you've added 'WITH SECURITY_ENFORCED'. Please check your code again."

Code is:-

@RestResource(urlMapping='/secureApexRest')
global with sharing class SecureApexRest {
    @HttpGet
    global static Contact doGet(){
        Id recordId = RestContext.request.params.get('id');
        Contact result;
        if (recordId == null){
            throw new FunctionalException('Id parameter is required');
        }
        if (Schema.SObjectType.Contact.isAccessible()
            && Schema.SObjectType.Contact.fields.Name.isAccessible()
            && Schema.SObjectType.Contact.fields.Secret_Key__c.isAccessible()){
            List<Contact> results = [SELECT id FROM Contact WHERE Id = :recordId WITH SECURITY_ENFORCED];
            if (!results.isEmpty()) {
                result = results[0];
            }
        } else{
            throw new SecurityException('You don\'t have access to all contact fields required to use this API');
        }
        return result;
    }
    public class FunctionalException extends Exception{}
    public class SecurityException extends Exception{}
}

Kindly suggest me what exactly I need to change in the code.
Thanks inadvance.

I am trying to solve one of the lightning trail heads of creating Camping list.

Here is my component.

<aura:component>
 <!-- PAGE HEADER -->
<aura:attribute name="newItem" type="Camping_Item__c"
    default="{ 'sobjectType': 'Camping_Item__c','Name': '',
             'Quantity__c': 0,
             'Price__c': 0,
             'Packed__c': false }"/>
<aura:attribute name="items" type="Camping_Item__c[]"/>


     
    <!-- PAGE HEADER -->
    <lightning:layout class="slds-page-header slds-page-header--object-home">
        <lightning:layoutItem>
            <lightning:icon iconName="standard:scan_card" alternativeText="Camping List"/>

Developer console is not opening.
It showing page loading since longer time.
So instead of Developer Console is there any other tool where we can write Lightning Component code?

Please help.
