title: Unable to load standard library for target arm64 error in XCode on Macbook Air M1
body: <p>On new Mac with M1 chip get the error after the build of React Native app in XCode 12.4:</p>
  <pre><code>unable to load standard library for target 'arm64-apple-ios8.0' 
  </code></pre>
  <blockquote>
  <p>failed to build module 'SciChart' from its module interface; the compiler that produced it, 'Apple Swift version 5.1.3 (swiftlang-1100.0.282.1 clang-1100.0.33.15)', may have used features that aren't supported by this compiler, 'Apple Swift version 5.3.2 (swiftlang-1200.0.45 clang-1200.0.32.28)'</p>
  </blockquote>
  <p>What I already tried:</p>
  <ol>
  <li>Reinstall XCode;</li>
  <li>Changed Swift Language Version;</li>
  <li>Deleted VALID_ARCHS reference according <a href="https://stackoverflow.com/questions/63029093/xcode-12-beta-2-unable-to-load-standard-library-for-target-arm64-apple-ios14">Xcode 12 Beta 2 - unable to load standard library for target &#39;arm64-apple-ios14.0-simulator&#39;</a></li>
  </ol>
  <p>On Macbook with intel chip there are no errors with the same app. And both of my Macbook have the same swift version:</p>
  <pre><code>Apple Swift version 5.3.2 (swiftlang-1200.0.45 clang-1200.0.32.28)
  Target: x86_64-apple-darwin20.3.0
  </code></pre>
  <p>Can you help me please!</p>
