Answer 1

This is an older question, and I'm sure you already found a solution that works for you...but there's actually really good documentation for how to implement select with tcomb-form-native. The stuff on the github page is just a starting point. Check out the extended documentation here

The github page also has additional documentation about Select if you scroll down toward the bottom under Select component: https://github.com/gcanti/tcomb-form-native

I have created a project that supports select (PickerIOS) and has a native look and feel. With my library (accessible at this link https://github.com/MichaelCereda/react-native-form-generator) you can do something like this.

import { Form, 
        PickerField
      } from 'react-native-form-generator';

 export class MyCoolComponent extends React.Component{
  handleFormChange(formData){
    /*
    formData will contain all the values of the form,
    in this example.

    formData = {
      gender: '',
    }
     */

   }
   render(){
      <Form
        ref='registrationForm'
        onChange={this.handleFormChange.bind(this)}
        name="Personal Information">
        
        <PickerField ref='gender' placeholder='Gender'
          options={{
            male: 'Male',
            female: 'Female'
          }}/>
        
      </Form>);
  }
}
