title: Objective C When running tests: Class defined without specifying a base class
body: <p>I have no idea what is going on as I am fairly new to objective c and IOS dev.</p>
  
  <p>When i try to run my tests, using the default testing framework i get the following error:</p>
  
  <pre><code>        ..../Pods/Expecta/src/matchers/EXPMatchers+beCloseTo.m:4:1: 
  Class 'EXPFixCategoriesBugEXPMatcher_beCloseToWithinMatcher' 
      defined without specifying a base class
  </code></pre>
  
  <p>The following peice of code generates the issue (however it is not mine, I believe it is a peice from one of the libraries I am using through pods):</p>
  
  <pre><code>#import "EXPMatchers+beCloseTo.h"
  #import "EXPMatcherHelpers.h"
  
  EXPMatcherImplementationBegin(_beCloseToWithin, (id expected, id within)) {
    prerequisite(^BOOL{
      return [actual isKindOfClass:[NSNumber class]] &amp;&amp;
          [expected isKindOfClass:[NSNumber class]] &amp;&amp;
          ([within isKindOfClass:[NSNumber class]] || (within == nil));
    });
  
    match(^BOOL{
          double actualValue = [actual doubleValue];
          double expectedValue = [expected doubleValue];
  
          if (within != nil) {
              double withinValue = [within doubleValue];
              double lowerBound = expectedValue - withinValue;
              double upperBound = expectedValue + withinValue;
              return (actualValue &gt;= lowerBound) &amp;&amp; (actualValue &lt;= upperBound);
          } else {
              double diff = fabs(actualValue - expectedValue);
              actualValue = fabs(actualValue);
              expectedValue = fabs(expectedValue);
              double largest = (expectedValue &gt; actualValue) ? expectedValue : actualValue;
              return (diff &lt;= largest * FLT_EPSILON);
          }
    });
  
    failureMessageForTo(^NSString *{
      if (within) {
        return [NSString stringWithFormat:@"expected %@ to be close to %@ within %@",
                EXPDescribeObject(actual), EXPDescribeObject(expected), EXPDescribeObject(within)];
      } else {
        return [NSString stringWithFormat:@"expected %@ to be close to %@",
                EXPDescribeObject(actual), EXPDescribeObject(expected)];
      }
    });
  
    failureMessageForNotTo(^NSString *{
