<p dir="auto">I have viewed the guide <a href="https://github.com/flutter/flutter/wiki/Add-Flutter-to-existing-apps">https://github.com/flutter/flutter/wiki/Add-Flutter-to-existing-apps</a>, it works.</p>
<p dir="auto">And so I want to use the output file (framework&amp; asset )to integrate to existing iOS APP. It seems simulator not support AOT ant it run in debug model with a VM.</p>
<p dir="auto">Current documentation (<a href="https://github.com/flutter/flutter/wiki/Flutter%27s-modes">https://github.com/flutter/flutter/wiki/Flutter%27s-modes</a>) states that Flutter release mode builds cannot be run on the Simulator. For many applications, the iOS Simulators are sufficiently high fidelity to do 99% of development work without going through the additional friction of deploying to devices regularly. It's unfortunate that, unlike in native application development, you can't get an accurate understanding of your release mode behaviors with Flutter.</p>
