To Reproduce
This is my configuration:

render() {
    let styleShadow = {}
    if (this.props.shadow) {
      styleShadow = {
        shadowColor: config.colors.black,
        shadowOffset: { width: 0, height: 3 },
        shadowOpacity: 0.15
      }
    }

    const style = [{
      paddingLeft: this.props.icon ? 40 : 15,
      paddingRight: 15,
      paddingTop: 10,
      paddingBottom: 10,
      backgroundColor: config.colors.white,
      borderColor: this.state.borderColor,
      borderWidth: 1,
      fontFamily: config.fonts.poppins,
      borderRadius: 10,
    }, styleShadow]

    return (
      <View style={[{
        marginBottom: 15,
        position: 'relative'
      }]}>
        <PickerSelect
          style={{
            inputAndroid: style,
            inputIOS: style,
            done: { color: config.colors.red },
            placeholder: { color: config.colors.black }
          }}
          items={this.props.items}
          onValueChange={this.props.onChangeText}
          placeholder={this.props.placeholder}
          value={this.props.value}
          useNativeAndroidPickerStyle={false}
          doneText="Confirm"
        />
      </View>
    )
  }

@gregogalante, noticed you closed this issue. Did you find a resolution to this? We’re getting the exact same error whenever we pass an empty array of items to the picker. Same details / env as you.

Right now we’re working around it by populating optimistically and then loading in the data from the API so the items are never empty.

My problem was related to the placeholder props. I pass a string as props insthead of an object with same keys like an option object.

I was also experiencing the same crash. Similar solution to above. I was already passing in a placeholder object like so -

placeholder={{label: someLabel, value: someValue}}

BUT, I discovered someLabel and someValue were undefined. So I had to ensure that those values were getting thru, and then it worked.
