Ionic emulate ios install an old version of the app

I’m trying the web version of the app: ionic serve and i did some changes, add new features, but when i run: ionic emulate ios, it install an old version of the app with out the new changes.

The transpiler is updateing the code, because if i introduce an error it detects it, also the tslints suggestions. But for some reason, xcode, or ionic emulate ios give and old version.

I already try removing www and platforms directories, and the app from the emulator
