If you want to create lightning with dynamic fields, retrieve the fieldset fields from server side and use lightning:recordEditForm 
<lightning:recordEditForm objectApiName="Contact">
        <lightning:messages />
        <lightning:inputField fieldName="FirstName" />
        <lightning:inputField fieldName="LastName" />
        <lightning:inputField fieldName="Email" />
        <lightning:inputField fieldName="AccountId" value="0011p00001ZQDGzAAP"/>
        <lightning:button class="slds-m-top_small" variant="brand" type="submit" name="update" label="Update" />
    </lightning:recordEditForm>
This can be changed to 
<aura:attribute name="fieldsAPIList" type="List"/>

<lightning:recordEditForm objectApiName="Contact">
         <aura:iteration items="{!fieldsAPIList}" var="fieldAPIName">
               <lightning:inputField fieldName="{!fieldAPIName}"/>
         </aura:iteration>
</lightning:recordEditForm>
But yes there are few issues with lightning:recordEditForm when used with Master-Detail field (without reparenting)
