it's not working. can anyone help me to how to access object inside object in laravel blade ?

Solution:

First check if $university->course is not empty:

{{ $university->course ? $university->course->course_name : 'Course Not Found' }}

Solution:

You can access like below if you are passing model object

 @foreach ($applicant_infos->universities as $university)
             <li>{{ $university->course->course_name }}</li>
          @endforeach

Updated.

you have to pass data to markdown like below

 return $this->markdown('emails.application_email',['app_body'=>$this->app_body,'applicant_infos'=>$this->applicant_infos]);
