No, the actual limitation is that you can’t implement a JIT compiler. You can’t create executable memory blocks unless you have a special entitlement only Apples Javascript engine has. Even using that engine your app must be self contained, you can’t download extra code, no matter the language. As your link says: > Apps should be self-contained in their bundles, and may not read or write data outside the designated container area, nor may they download, install, or execute code which introduces or changes features or functionality of the app, including other apps.
