                        <View
                            style={{
                                flex: 1,
                                justifyContent: 'center',
                                alignItems: 'center',

                            }}>
                            <ActivityIndicator size={'large'} color={colors.primary}/>

                        </View>
                        :

                        <Swiper
                            showsButtons={false}
                            onIndexChanged={this.onIndexChanged}
                            loop={false}
                            index={this.state.sliderIndex}
                            paginationStyle={{
                                bottom: -25
                            }}
                        >
                            {this.renderControls()}
                        </Swiper>
                    }

Start by reproducing the reported iOS behavior with react-native-swiper v1.5.14 and React Native v0.58.4, focusing on the Swiper index prop and onIndexChanged handler shown in the report. Clarify what “deteriorates” means from the screenshot, then verify that selecting an index leaves the swiper rendering correctly.
