Picker iOS errror

[mbs8]

I had this issue when tried to use the picker field, I think the error is in:
picker/index.js#L27
on line 57

      <View
        style={Object.assign(styles.pickerMainIOS, {
          backgroundColor: theme.pickerBgColor,
          borderBottomColor: theme.inputBorderColor,
          borderBottomWidth: theme.borderWidth,
        })}
     >

It works fine like this:

      <View
        style={{...styles.pickerMainIOS, ...{
          backgroundColor: theme.pickerBgColor,
          borderBottomColor: theme.inputBorderColor,
          borderBottomWidth: theme.borderWidth,
        }}}
      >

I also got the same issue, and making the changes suggested above on Line 57 /src/fields/picker/index.js fixed it. Thank you @mbs8 !
