Xcode Compile Flag to Suppress Nullability Warnings not Working?
<p>For a limited time I want to suppress these kind of warnings the compiler is showing me in Xcode 7.3.1:</p>

<p><code>&lt;File&gt;: Pointer is missing a nullability type specifier (_Nonnull, _Nullable, or _Null_unspecified)</code></p>

<p>I have added this compiler flag to all classes under My Target/Build Phases/Compile Sources:
<code>-Wnullability-completeness</code></p>

<p>But it's not working - the warnings are still shown. How can I get rid of the warnings?</p>
