Async of Swim: basic case. Replace route with Ember Concurrency Task

route.js

// In your route...
import Route from '@ember/routing/route';
import { task } from 'ember-concurrency';
export default Route.extend({
  model: function (){
    return {
      blog: this.get('blogTask').perform()
    };
  },
  blogTask: task(function *(){
    let blog = yield this.get('store').queryRecord('blog', {today:true});
    return blog;
  });
});

template.hbs

// In your template...
{{#if model.blog.isRunning}}
    LOADING...
{{else}}
   {{model.blog.value.title}}
{{/if}}
