title: Security issue in iOS app build: The binary may contain the following banned API(s) _memcpy, _alloca, _gets
body: <p>My iOS app is developed in swift. It contains some cocoa pods and other trusted third party frameworks. Build is stable and in running mode. Now when security official has done a security assessment on the app they have come up with above mentioned issue. The app was shared in installable forms and somehow they have used some tools to analyze the app(though ipa was not shared directly tool raised this issue in app ipa, tool is unknown here).</p>
  
  <p>Now when I search for above mentioned API's as keywords in the whole project , I don't find its usage. Can anyone help on this , on how to trace if our code / other libraries are using these API's or not, if using , how one can rectify its usage?</p>
