I can't understand why this if statement doesn't work in Swift

I hope this helps you . The code you put in viewDidLoad is executed once, when the view is loaded - it isn't triggered every time numbers is updated.
To implement what you need, you should make number an instance property, and add a didSet observer:
code :
class ViewController: UIViewController {
    var numbers: Int = 0 {
        didSet {
            if numbers == 5 {
                labelStatus.text = "Numbers variable is equal to 5! Hurray!"
            }
        }
    }
    ...
}

With these it helps If the code you want to run after the if conditional is only one line you can omit the brackets. I find it confusing, so I don't do it but it is valid PHP.
So, what your code does works:
code :
if(empty($paged)) $paged = 1;
if(empty($paged)) 
    $paged = 1; // semi-colon marks the end of the line
if(empty($paged)) $paged = 1; $othervar = 2;
if(empty($paged)) 
   $paged = 1; 
   $othervar = 2;

it should still fix some issue The order of if and foreach in first case are wrong. See fixed and optimized variant:
code :
<?php $strRendersettings = ($this->settings)? 'settings' : 'view'; ?>
<?php if (count($this->data)): ?>
    <ul>
        <?php
        $match = "";
        switch($_SERVER['HTTP_HOST'])
        {
            case "dev.domain.de":
                $match = "Deutsch";
                break;

            case "dev.domain.com":
                $match = "Englisch";
                break;

            case "dev.domain.fr":
                $match = "Franzoesisch";
                break;

        }

        foreach ($this->data as $arrItem) {
            if ($arrItem['text']['new_docs_auswahl'] == $match){
                ?>
                <li class="new_doc_home"><a href="" ><strong><?=$arrItem['text']['new_docs_titel']?>:</strong><br></a>
                        <p><a href="" ><?=$arrItem['text']['new_docs_Text']?></a></p>
                    <?=$arrItem['text']['new_docs_auswahl']?>
                </li>
                <?
            }
        }
        ?>
    </ul>
<?php endif; ?>

I wish did fix the issue. Strings are compared using .equals rather than ==.
So replace if (StaffActivity.art == "F") with if (StaffActivity.art.equals("F")).
