    {
        $contacts = Contact::all();
        return view('contact.index')->with('contacts',$contacts);
    }

View Page

@extends('layout')

@section('content')

<div class="card">
        <div class="card-header">About</div>
        <div class="card-body">  

            @foreach($contacts as $contact)
            <p>{{ $contact->name }}</p>
            <p>{{ $contact->address }}</p>
            <p>{{ $contact->mobile }}</p> 
            @endforeach
        </div>
    </div>

Routes

use App\Http\Controller\ContactController;

    Route::resource('/contact',ContactController::class);

>Solution :

The controllers live in App\Http\Controllers, so edit

use App\Http\Controller\ContactController;

to

use App\Http\Controllers\ContactController;

make sure the file namespace is correct too
