A terrible, but functioning workaround is to copy the web-app to the resource directory *after* Alloy and the Titanium CLI are done with compiling, but before packaging:

   exports.cliVersion = '>=3.2';
   
   var path = require("path"),
     wrench = require('wrench');
   
   exports.init = function(logger, config, cli, appc) {
   
     if (cli.argv.platform !== 'android') {
   
       cli.addHook('build.post.compile', function(build, finished) {
   
         logger.log("======= COPYING 'WWWW' =======");
   
         var source = path.join(build.projectDir, "www");
         var destination = path.join(build.xcodeAppDir, "www");
   
         wrench.copyDirSyncRecursive(source, destination, {
           forceDelete: true,
           preserveFiles: false
         });
   
         finished();
       });
   
     } else {
   
       cli.addHook('build.android.writeAndroidManifest', function(opts, finished) {
   
         logger.log("======= COPYING 'WWWW' =======");
   
         var source = path.join(opts.ctx.projectDir, "www");
         var destination = path.join(opts.ctx.buildDir, "bin", "assets", "Resources", "www");
   
         wrench.copyDirSyncRecursive(source, destination, {
           forceDelete: true,
           preserveFiles: false
         });
   
         finished();
       });
   
     }
   };

Moving this ticket to engineering as I can reproduce the issue with the provided test case.

A better workaround we just came across is using *Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory).getNativePath()* when building the webView url instead of using only *Ti.Filesystem.applicationDataDirectory* It works but still, a proper fix would be nice.

I used the approach of Fokke and it works for development and app store builds for iOS, but fails when doing an ad-hoc build as you get the error: Failed to verify code signature of /some/path/myapp.app : 0xe8008017 (A signed resource has been added, modified, or deleted.) I guess it is because you add something to the build after some signing has been done. If someone knows a workaround for this, I'll be glad to hear!
