title: -[__NSCFString setLineWidth:]: unrecognized selector sent to instance
body: <p>When I am running my application I am getting the following exception:</p>
  
  <blockquote>
    <p>[__NSCFString setLineWidth:]: unrecognized selector sent to instance 0x15b1ae00</p>
  </blockquote>
  
  <p>and the app is crashing.
  If I create a <code>UIBezierPath</code>, it works, but when I have the same <code>UIBezierPath</code> shared from other user, it crashes.</p>
  
  <pre><code>&lt;UIBezierPath: 0x175005a0; &lt;MoveTo {250, 466}&gt;,
  &lt;CurveTo {268, 344} {246, 453} {247, 440}&gt;,
  &lt;MoveTo {268, 344}&gt;,
  &lt;CurveTo {271, 327} {271, 332} {271, 323}&gt;,
  &lt;MoveTo {271, 327}&gt;,
  &lt;CurveTo {273, 360} {271, 336} {272, 346}&gt;,
  &lt;MoveTo {273, 360}&gt;,
  &lt;CurveTo {295, 379} {282, 381} {287, 383}&gt;,
  &lt;MoveTo {295, 379}&gt;,
  &lt;CurveTo {312, 337} {302, 363} {308, 347}&gt;,
  &lt;MoveTo {312, 337}&gt;,
  &lt;CurveTo {324, 316} {317, 323} {320, 320}&gt;,
  &lt;MoveTo {324, 316}&gt;,
  &lt;CurveTo {343, 295} {330, 311} {336, 303}&gt;,
  &lt;MoveTo {343, 295}&gt;,
  &lt;CurveTo {356, 276} {348, 289} {355, 278}&gt;
  </code></pre>
  
  <p>The only difference is 0x175005a0. How Can I solve it?</p>
