"data" is not used in iOS, remove.

If you want the file to be in the application bundle, use bundle_data target
instead ("git grep bundle_data" for examples).

This should not be necessary, output_dir defaults to target_gen_dir (see
"tools/grit/grit_rule.gni" line 329). target_gen_dir is by default equal to
"$root_gen_dir/ios/web" for that target (for a target defined in
"//foo/bar/BUILD.gn", then target_gen_dir is equal to "$root_gen_dir/foo/bar").

You can confirm this by checking that the output of //ios/web:resources_grit
target are located into //$root_out_dir/gen/ios/web using the following command
without your patch:

$ gn desc out/gn-Debug-iphonesimulator //ios/web:resources_grit outputs
  //out/gn-Debug-iphonesimulator/gen/ios/web/resources_stamp.d.stamp
  //out/gn-Debug-iphonesimulator/gen/ios/web/grit/ios_web_resources.h
  //out/gn-Debug-iphonesimulator/gen/ios/web/ios_web_resources.pak


Remove.
