title: IOS RxSwift Create Array of Observable from Observable array
body: <p>I'm building a chain function which the flow is to take result from previous function and loop through each element do some calculation and final return back the original array</p>
  
  <p>I have </p>
  
  <pre><code>func(A) -&gt; Observable&lt;[Object]&gt;
  func(B)(Object) -&gt; Observable&lt;Object&gt;
  </code></pre>
  
  <p>How do we make the chaining like this?</p>
  
  <pre><code>Observable&lt;[Object]&gt; -&gt; [Observable&lt;Object&gt;] -&gt; Observable&lt;[Object]&gt;
  </code></pre>
