• Sorry, in order to call mocl from swift you must first create wrapper methods in Objective-C that enclose the desired calls. For example:
  
  - (void)formatHello:(NSString *)arg {
    format_hello(arg);
  }
  
  then formatHello can be called from swift. Note: in the future mocl could autogenerate swift bindings, but for now, it is a manual process.

• Thanks for help! It would be awesome if mocl could generate swift bindings.
  Meanwhile here's how I did it:
  
  1. Create new Objective-C file mocl_bridge.m
  2. Open mocl_bridge.m and add following:
  
  #import <Foundation/Foundation.h>
  #import <CoreGraphics/CGBase.h>
  #import "mocl.h"
  
  NSString* formatHello(NSString *arg) {
    return format_hello(arg);
  }
  
  3. Edit Project settings > Swift Compiler - Code Generation > Objective-C Bridging Header, add mocl_bridge.m (include relative path to file if needed)
  
  4. Edit button action method in ViewController.swift:
  
  @IBAction func btnHelloAction(sender: AnyObject) {
    let name = txtField.text
    lblHello.text = formatHello(name);
  }
  
  Now it should successfully compile and run.
