The iOS Simulator uses the host machine network so you should be able to just use localhost or your machines IP address, whichever IP your web service is listening on.

In swift 5 just call:

    http://localhost:&lt;port&gt;/file_path 

but you will need to add this part to the project `Info.plist`.

    &lt;key&gt;NSAppTransportSecurity&lt;/key&gt;
    &lt;dict&gt;
        &lt;key&gt;NSAllowsArbitraryLoads&lt;/key&gt;
            &lt;true/&gt;
    &lt;/dict&gt;  

Otherwise this error is going to happen.

`Cannot start load of Task &lt;xx-xx&gt;.&lt;x&gt; since it does not conform to ATS policy.`

How can we convert a JavaScript string variable to decimal?

convert a JavaScript string variable to decimal/money

I am using R to parse a list of strings in the form:

    original_string &lt;- &quot;variable_name=variable_value&quot;

First, I extract the variable name and value from the original string and convert the value to numeric class. 

    parameter_value &lt;- as.numeric(&quot;variable_value&quot;)
    parameter_name &lt;- &quot;variable_name&quot;
    
Then, I would like to assign the value to a variable with the same name as the `parameter_name` string.

    variable_name &lt;- parameter_value

What is/are the function(s) for doing this?

I&#39;m developing an app that connects to a web service for most of it&#39;s operations. As a shortcut, I&#39;d like to run a copy of my development server on my machine. Question is:

How/can I access the host machine&#39;s network (http in this case) from the iPhone simulator?

I&#39;m developing the web service alongside the app, so it would be helpful to have them both on the host machine, and then I can commit changes as needed.

I&#39;m developing an IOS app that creates files on the device, e.g. with `NSKeyedArchiver`.

During Android development it&#39;s possible to browse a device filesystem when it&#39;s connected to your workstation via USB, for instance to help with troubleshooting your app.

However for IOS I don&#39;t see anything similar under the Organizer in Xcode, to help me browse files my app creates from the workstation. Googling &quot;iOO browse device files&quot;, &quot;iPhone view files&quot; etc. reveals solutions for jailbroken devices but not for regular devices provisioned for development.

I have a project (`AQGridView`) that compiles to a static library, but I can&#39;t seem to add it to my project.

Dragging in the project to my project creates a workspace, and if I try to link the `libAQGridView.a` file from the `DerivedData` directory it doesn&#39;t recognize it as a library.  I&#39;m not sure what I&#39;m doing wrong.

This is the `AQGridView` project.  Does anyone know specifically how to use it in an Xcode 4 project?

Given an `NSArray` of `NSDictionary` objects (containing similar objects and keys) is it possible to write perform a map to an array of specified key? For example, in Ruby it can be done with:

    array.map(&amp;:name)

NSArray Equivalent of Map

I&#39;m using this method to copy a file:

    [fileManager copyItemAtPath:sourcePath toPath:targetPath error:&amp;error];

I want to overwrite a file when it exists already. The default behavior of this method is to throw an exception/error &quot;File Exists.&quot; when the file exists. There&#39;s no option to specify that it should overwrite.

So what would be the safest way to do this?

Would I first check if the file exists, then delete it, and then attempt to copy? This has the danger that the app or device goes OFF right in the nanosecond after the file has been deleted but the new file hasn&#39;t been copied to that place. Then there&#39;s nothing.

Maybe I would have to change the name of the new file first, then delete the old, and then re-change the name of the new? Same problem. What if in this nanosecond the app or device goes OFF and renaming doesn&#39;t happen?

I have an attribute of type `BOOL` and I want to perform a search for all managed objects where this attribute is `YES`.

For string attributes it is straightforward. I create a predicate like this:

    NSPredicate *predicate = [NSPredicate predicateWithFormat:@&quot;userName = %@&quot;, userName];

But how do I do this, if I have a bool attribute called *selected* and I want to make a predicate for this? Could I just do something like this?

    NSPredicate *predicate = [NSPredicate predicateWithFormat:@&quot;selected = %@&quot;, yesNumber];

Or do I need other format specifiers and just pass `YES`?
