The easiest way is to use:  <lightning:inputField fieldName="{!myfield}"/> inside a <lightning:recordEditForm> with an <aura:iteration>

The fields 'Name', 'Industry' and 'Website' of Account are displayed dynamically without a complex component creation (a list is sufficient). 
 
<aura:component implements="force:lightningQuickAction,force:appHostable,flexipage:availableForRecordHome,force:hasRecordId"> 
    <aura:attribute name="showSpinner" type="Boolean" default="false" />   
    <aura:handler name="init" value="{!this}" action="{!c.doInit}"/>
    <aura:attribute name="myfields" type="List" default="[]"/>
    
    <aura:if isTrue="{!v.showSpinner}">
        <lightning:spinner />
    </aura:if>
    
    <lightning:notificationsLibrary aura:id="notifLib1" />       
    
    <lightning:card>    
        <lightning:recordEditForm 
                                  recordId="{!v.recordId}"
                                  objectApiName="Account"
                                  onload="{!c.handleLoad}"
                                  onsuccess="{!c.handleSuccess}"
                                  onerror="{!c.handleError}">
            <lightning:messages />
            <aura:iteration items="{!v.myfields}" var="myfield">
                <lightning:inputField fieldName="{!myfield}"/><br/> 
            </aura:iteration>         
            <lightning:button class="slds-m-top_small" type="submit" variant="brand" label="Save" onclick="{!c.handleSave}" />
        </lightning:recordEditForm>
    </lightning:card>
    
</aura:component>
 
({
     doInit: function(cmp) {
         cmp.set('v.myfields', [ 'Name', 'Industry', 'Website' ]);
    },
    handleSuccess: function (cmp, event, helper) {
        cmp.find('notifLib1').showToast({
            "title": "Record updated!",
            "message": "The record has been updated successfully.",
            "variant": "success"
        });
        cmp.set("v.showSpinner", false);
    },
    handleError: function (cmp, event, helper) {
        cmp.find('notifLib1').showToast({
            "title": "Something has gone wrong!",
            "message": event.getParam("message"),
            "variant": "error"
        });
    },    
    handleLoad : function(cmp, event, helper) {
        cmp.set("v.showSpinner", false);
    },   
    handleSave : function(cmp, event, helper) {
        cmp.set("v.showSpinner", true);
    },
})
