OK so after more testing, turns out you just have to set:

    searchController.active = false
    // or swift 4+
    searchController.isActive = false


This is the first thing I tried but I called it in one of the UISearchControllerDelegate methods which didn&#39;t work (probably should have called it with dispatch_async (halbano&#39;s answer seems to confirm that)).

Anyway, since I couldn&#39;t find that answer online, I&#39;m answering my own question, I hope that it&#39;ll help someone.

Did you have this problem when you try to dismiss search controller after segueing to another view? I have encountered this problem too. I think you might want to use 

    self.definesPresentationContext = true 
in the view controller that presents the UISearchController as per this post &lt;https://stackoverflow.com/questions/29610873/uisearchcontroller-not-dismissed-when-view-is-pushed&gt;. It works for me.

I was presenting the mine embed on a navigation bar. The code that works for me was:

    - (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar{
        dispatch_async(dispatch_get_main_queue(), ^{
            [self.searchController setActive:NO];
            self.navigationController.navigationBar.topItem.title = @&quot;MYTITLE&quot;.uppercaseString;
            self.navigationItem.titleView = nil;
        });
    }

Hope it helps someone.

SWIFT 4+

    searchController.isActive = false

I had this problem using the search and interactionController, solved after just include the line: 
    self.dismissViewControllerAnimated(false, completion: nil)

Open the interaction and clear the search without changes in the delegate.

I am making an API with `Laravel 5` and I&#39;m testing it with `PHPUnit`. I need to test legacy functionality for compatibility, which is an XML POST. As of right now, my first test looks like:

    public function testPostMessages()
	{
		$response = $this-&gt;call(&#39;POST&#39;, &#39;xml&#39;);

		$this-&gt;assertEquals(200, $response-&gt;getStatusCode());
	}

This is passing just fine. Next on my list is actually sending the XML data with the POST. So for my second test, I have:

    public function testPostMessagesContent()
	{
		$response = $this-&gt;call(&#39;POST&#39;, &#39;xml&#39;);

		$this-&gt;assertTrue(is_valid_xml($response-&gt;getContent()));
	}

This test fails. However, I am not sending my XML data. &lt;strong&gt;How do I send my XML?&lt;/strong&gt;&lt;br /&gt;
Now, after that I need to add in the functionality to get the content from the request. I know there is a `Request` object that I can interact with but I don&#39;t exactly know which method to call on it. &lt;strong&gt;How do I get my XML from inside my controller?&lt;/strong&gt;&lt;br /&gt;
&lt;hr /&gt;
&lt;h3&gt;Update #1&lt;/h3&gt;
I was able to get some results in the meantime. My current test looks like this:

    public function testPostMessagesContent()
	{
		$response = $this-&gt;call(&#39;POST&#39;, &#39;xml&#39;, array(&#39;key&#39; =&gt; &#39;value&#39;), array(), array(), array(&#39;content&#39; =&gt; &#39;content&#39;));
		$this-&gt;assertContains(&#39;~&#39;, $response-&gt;getContent());
	}

I only have the tilde there because I know it won&#39;t match so that I can see the whole response. In `XmlController.php` I have:

    class XmlController extends Controller {
	public function index(Request $request)
	{
		return $request;
    	}
    }

My output from `PHPUnit` is as follows:

    1) XmlTest::testPostMessagesContent
    Failed asserting that &#39;POST xml HTTP/1.1
    Accept:          text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
    Accept-Charset:  ISO-8859-1,utf-8;q=0.7,*;q=0.7
    Accept-Language: en-us,en;q=0.5
    Content-Type:    application/x-www-form-urlencoded
    Host:            localhost
    User-Agent:      Symfony/2.X
    &#39; contains &quot;~&quot;.

Where are my parameters and my content? I feel like I am simply just using `call()` incorrectly.
&lt;hr /&gt;
&lt;h3&gt;Update #2&lt;/h3&gt;
I updated my controller to use `Request:all()` like so:

    class XmlController extends Controller
    {
        public function index()
       {
            $content = Request::all();
            return $content;
        }
    }

This returned my key-value pair, but not the content.

    1) XmlTest::testPostMessagesContent
    Failed asserting that &#39;{&quot;key&quot;:&quot;value&quot;}&#39; contains &quot;~&quot;.

Key-value pairs are good; it&#39;s progress. However, what I really need is the content since I&#39;ll be receiving that data in the content portion of the request. If I use `Request::getContent()` I get back a blank string. Here&#39;s my call in the test:

    $response = $this-&gt;call(&#39;POST&#39;, &#39;xml&#39;, array(&#39;key&#39; =&gt; &#39;value&#39;), array(), array(), array(&#39;content&#39; =&gt; &#39;content&#39;));

Here&#39;s my test results:

    1) XmlTest::testPostMessagesContent
    Failed asserting that &#39;&#39; contains &quot;~&quot;.
&lt;hr /&gt;
&lt;h3&gt;Update #3&lt;/h3&gt;
I am not able to get the content body of an HTTP Request at all. Since XML wasn&#39;t working, I moved forward with the REST part of my API, which uses JSON. Here&#39;s one of my tests:

    public function testPostMessagesContent()
	{
		$response = $this-&gt;call(&#39;POST&#39;, &#39;messages&#39;, [&#39;content&#39; =&gt; &#39;content&#39;]);

		$this-&gt;assertEquals(&#39;saved!&#39;, $response-&gt;getContent());
	}

This test passes. If I use curl, I get a successful call as well:

    curl -X POST -d &quot;content=my_new_content&quot; &quot;http://localhost:8000/messages&quot;

This returns `&#39;saved!&#39;` That&#39;s awesome, but if I try to use curl in a standalone PHP script (to simulate a client), this is what is returned:

    Array ( [url] =&gt; http://localhost:8000/messages [content_type] =&gt; text/html; charset=UTF-8 [http_code] =&gt; 302 [header_size] =&gt; 603 [request_size] =&gt; 118 [filetime] =&gt; -1 [ssl_verify_result] =&gt; 0 [redirect_count] =&gt; 0 [total_time] =&gt; 0.063977 [namelookup_time] =&gt; 0.000738 [connect_time] =&gt; 0.000866 [pretransfer_time] =&gt; 0.000943 [size_upload] =&gt; 12 [size_download] =&gt; 328 [speed_download] =&gt; 5126 [speed_upload] =&gt; 187 [download_content_length] =&gt; -1 [upload_content_length] =&gt; 12 [starttransfer_time] =&gt; 0.057606 [redirect_time] =&gt; 0 [certinfo] =&gt; Array ( ) [primary_ip] =&gt; ::1 [primary_port] =&gt; 8000 [local_ip] =&gt; ::1 [local_port] =&gt; 63248 [redirect_url] =&gt; http://localhost:8000 [request_header] =&gt; POST /messages HTTP/1.1 Host: localhost:8000 Accept: */* Content-type: text/xml Content-length: 12 ) Redirecting to http://localhost:8000. 

This is my curl command adding the POST fields:

    curl_setopt($ch, CURLOPT_POSTFIELDS, &#39;content=test&#39;);

It seems to me that POSTFIELDS is getting added to the body of the request. In this case, I still have the same problem. I am not able to get body content of my HTTP headers. After commenting out my validation, I get:

    Array ( [url] =&gt; http://localhost:8000/messages [content_type] =&gt; text/html; charset=UTF-8 [http_code] =&gt; 200 [header_size] =&gt; 565 [request_size] =&gt; 118 [filetime] =&gt; -1 [ssl_verify_result] =&gt; 0 [redirect_count] =&gt; 0 [total_time] =&gt; 0.070225 [namelookup_time] =&gt; 0.000867 [connect_time] =&gt; 0.00099 [pretransfer_time] =&gt; 0.001141 [size_upload] =&gt; 12 [size_download] =&gt; 6 [speed_download] =&gt; 85 [speed_upload] =&gt; 170 [download_content_length] =&gt; -1 [upload_content_length] =&gt; 12 [starttransfer_time] =&gt; 0.065204 [redirect_time] =&gt; 0 [certinfo] =&gt; Array ( ) [primary_ip] =&gt; ::1 [primary_port] =&gt; 8000 [local_ip] =&gt; ::1 [local_port] =&gt; 63257 [redirect_url] =&gt; [request_header] =&gt; POST /messages HTTP/1.1 Host: localhost:8000 Accept: */* Content-type: text/xml Content-length: 12 ) saved!

So I have my `&#39;saved!&#39;` message. Great! But, in my database now I have a blank row. Not great. It is still not seeing the body content, just the headers.&lt;br /&gt;
&lt;hr /&gt;
&lt;h3&gt;Answer Criteria&lt;/h3&gt;
I&#39;m looking for the answers to these questions:
&lt;ol&gt;
&lt;li&gt;Why can&#39;t I get the body content of my request?&lt;/li&gt;
&lt;li&gt;How do I get the body content of my request?&lt;/li&gt;
&lt;/ol&gt;

This must be trivial, but I can&#39;t find how you&#39;re supposed to dismiss a UISearchController programmatically?

Note that it&#39;s the new UISearchController (introduced in 2014 with iOS 8), not the UISearchDisplayController.

So far here&#39;s what I&#39;ve got

    // Dismiss the search tableview
    searchController.dismissViewControllerAnimated()
    // Clear the Search bar text
    searchController.active = false

But I still have the cancel button and can&#39;t get rid of it.

I want to delete the first character from a string. So far, the most succinct thing I&#39;ve come up with is:

    display.text = display.text!.substringFromIndex(advance(display.text!.startIndex, 1))

I know we can&#39;t index into a string with an `Int` because of Unicode, but this solution seems awfully verbose. Is there another way that I&#39;m overlooking?

What is the most succinct way to remove the first character from a string in Swift?

I need to check if a double-defined variable is convertible to Int without losing its value. This doesn&#39;t work because they are of different types:
   
    if self.value == Int(self.value)
where `self.value` is a double.

I have a string like this

    var str = &quot;@text1 this is good @text1&quot;
Now replace `text1` with another string, say `t 1`. I am able to replace the text, but i am not able to bold it. I want to bold the new string `t 1`, so that the final output will be:

**@t 1** this is good **@t 1**

_How can I do it?_ 

All the examples I am seeing are in Objective-C, but I want to do it in Swift.

Thanks in advance.

Making text bold using attributed string in swift

I have this problem with `po` in the console where trying to output a function works in itself, but outputting a variable or constant doesn&#39;t.

![first result is for `po bar.boy()`, second says `unresolved`][1]


  [1]: http://i.stack.imgur.com/G8qC1.png
As you can see here, although you&#39;d think the var/let holds the content of `bar.boy()`, Swift somehow can&#39;t find it...

`po` gives `error: &lt;EXPR&gt;:1:1: error: use of unresolved identifier`

I have code that creates a `UISearchController&#39; in my UIVIew&#39;s `viewDidLoad`.

            controller.searchResultsUpdater = self
            controller.searchBar.delegate = self
            controller.dimsBackgroundDuringPresentation = false
            controller.searchBar.sizeToFit()
            controller.hidesNavigationBarDuringPresentation = false //prevent search bar from moving
            controller.searchBar.placeholder = &quot;Search for song&quot;
            
            self.myTableView.tableHeaderView = controller.searchBar
            
            return controller
            
        })()

Attempting to load the view of a view controller while it is deallocating... UISearchController

The structure:

View1 (click a button) -&gt; present modally (MyModalView: UITableViewController)

MyModalView has UISearchController embedded. The searchBar of UISearchController is placed in MyModalView.tableView.tableHeaderView.

It&#39;s been working fine since iOS 8.0. However on iOS 9, the searchBar disappear when the UISearchController is active. Please take a look at theses pictures below

The modal view:[![modal view][1]][1]

UISearchController active on iOS 8:[![search bar in iOS 8][2]][2]

UISearchController active on iOS 9:[![search bar in iOS 9][3]][3]

The very standard code:

    override func viewDidLoad() {
        super.viewDidLoad()

        // Dynamically create a search controller using anonymous function
        self.resultSearchController = ({
            let controller = UISearchController(searchResultsController: nil)
            controller.searchResultsUpdater = self
            controller.dimsBackgroundDuringPresentation = false

            controller.searchBar.sizeToFit()
            controller.searchBar.delegate = self

            self.tableView.tableHeaderView = controller.searchBar

            return controller
        })()

        // Auto sizing row &amp; cell height
        self.tableView.estimatedRowHeight = 130
        self.tableView.rowHeight = UITableViewAutomaticDimension
        self.definesPresentationContext = true

        // No footer for better presentation
        self.tableView.tableFooterView = UIView.init(frame: CGRectZero)
    }

This issue also happens in iOS 9.1 beta... 

Any idea / pointer would be deeply appreciated

Cheers.

iOS 9 searchBar disappears from table header view when UISearchController is active

I had been using the following code prior to iOS 11 to customize the appearance of the `UISearchController` search bar:

    var searchController = UISearchController(searchResultsController: nil)
    searchController.searchBar.setDefaultSearchBar()
    searchController.searchResultsUpdater = self

    if #available(iOS 11.0, *) {
        navigationItem.searchController = searchController
    } else {
        tableView.tableHeaderView = searchController.searchBar
    }

    extension UISearchBar {
        func setDefaultSearchBar() {
            self.tintColor = UIColor.blue
            self.searchBarStyle = .minimal
            self.backgroundImage = UIImage(color: UIColor.clear)
            let searchBarTextField = self.value(forKey: &quot;searchField&quot;) as! UITextField
            searchBarTextField.textColor = UIColor.white
            searchBarTextField.tintColor = UIColor.blue
            searchBarTextField = .dark
        }
    }

However, the appearance of the search bar fails to update when running the same code on iOS 11.

Much of the attention to this question so far has focused on the text color of the search bar. I am looking at more than this - the background color, tint color, the search indicator, clear button color, etc.

UISearchController iOS 11 Customization

I’m attaching a UISearchController to the `navigationItem.searchController` property of a UITableViewController on iOS 11. This works fine: I can use the nice iOS 11-style search bar.

However, I’d like to make the search bar visible on launch. By default, the user has to scroll up in the table view to see the search bar. Does anyone know how is this is possible?

[![enter image description here](https://i.stack.imgur.com/6I4uKm.png)](https://i.stack.imgur.com/6I4uK.png)
[![enter image description here](https://i.stack.imgur.com/6ApdIm.png)](https://i.stack.imgur.com/6ApdI.png)

*Left: default situation after launch. Right: search bar made visible (by scrolling up). I’d like to have the search bar visible after launch, as in the right screenshot.*

I already found that the search bar can be made visible by setting the property `hidesSearchBarWhenScrolling` of my navigation item to false. However, this causes the search bar to always be visible — even when scrolling down —, which is not what I want.

Show search bar in navigation bar without scrolling on iOS 11

I implemented Dark Mode with the current beta version of Xcode in a relatively old&#160;app. I uploaded these to TestFlight for my&#160;testers. However, this crashes immediately for anyone who has the public beta of iOS&#160;13.

I&#39;ve integrated Crashlytics into the app, and the cause of these crashes is as&#160;follows:

&gt; `UISearchDisplayController` is no longer supported when using this version of&#160;iOS. Please migrate your application to&#160;`UISearchController`.

All `UISearchDisplayController` instances have already been replaced by the&#160;`UISearchController`. The app doesn&#39;t use the `UISearchDisplayController` anymore. There is no longer any links to the `UISearchDisplayController`. Nevertheless, these crashes continue to occur, but only from the installations of&#160;TestFlight.

If the app is installed directly with Xcode as a &quot;Debug&quot; or &quot;Release&quot; on an iPhone with the public beta, the crash does not&#160;occur.

Does anyone have a solution for this problem?
