You need to parse the first res into json

fetch('https://api.chooin.com/v1/product/index')
    .then(res => res.json())
    .then(data => {
        return this.setState({
            loaded: true,
            products: this.state.products.cloneWithRows(data.subjects)
        });
    })
    .catch(err => console.log(err));

I parse the first res,but also request failed. – Devin Oct 03 '16 at 04:55
So in ios8.3 you get the data but ios 10 not working ? The only way I was thinking was http and not https but your are already using https. – EQuimper Oct 03 '16 at 05:06
