swiper stope. It's not moving

I use react-native-swiper in my home screen, fist time I installed it basically: npm i --save react-native-swiper then I got an error with viewpagerandroid and the new version of RN: 0.61.2. I got that I have to install another version of swiper : npm i --save react-native-swiper@nightly and then no error but my swiper dont work: buttons are clockable but images don't swipe and i can't swipe it manually. this is my code:

<Swiper
    index={this.state.firstSlide}
    autoplay={true}
    autoplayTimeout= {2}
    loop={true}
    style={Styles.slider}
    showsButtons={true}
    showsPagination={true}
    buttonTextStyle={{color:'#9e9e9e', fontSize:24}}
  >



{this.state.slides.map((item, key) => {
      return(
          <ImageBackground
            key={key}
            style={Styles.slide1}
            source={{uri: 'https://www.website.com/folder1/api/../' + item.path}}
            resizeMode={'cover'}
            blurRadius={2}
            opacity= {0.7}
            >
              <Image
                source={{uri: 'https://www.website.com/folder1/api/../' + item.path}}
                style={Styles.imageStyle}
                resizeMode={'contain'}
              />
          </ImageBackground>
      );
  })}

  </Swiper>

ps. this code work for me in other project with other version of RN: 0.59.1 and R-N-Swiper when I try to use juste an easy example:

<Swiper style={styles.wrapper} showsButtons={true}>
    <View style={styles.slide1}>
      <Text style={styles.text}>Hello Swiper</Text>
    </View>
    <View style={styles.slide2}>
      <Text style={styles.text}>Beautiful</Text>
    </View>
    <View style={styles.slide3}>
      <Text style={styles.text}>And simple</Text>
    </View>
  </Swiper>

button are clickable but this time pagination works to but only the last view is shown!
