IOS React natif fetch() POST: Échec de la demande réseau

Question

1) Le code suivant me donne une erreur sur IOS mais fonctionne sur Android.

2) On peut faire IOS i avec chercher "obtenir", mais "post" échoue

donc ce ne fonctionne pas sur ios:

var data = new FormData(); 
    data.append("fileUpload", { uri: imageUri, name: filename, type: "image/jpeg" }); 
    data.append("filename", filename); 
    data.append("name", "uploadedFile"); 
    const config = { 
     method: "POST", 
     headers: { 
      Accept: "application/json", 
      "Content-Type": "multipart/form-data;" 
     }, 
     body: data 
    }; 

    return fetch(url, config).then((response) => response.json()) 
     .then(res => { return res ;}) 
     .catch(error => { 
      console.error(error); 
      return { name: "network error", description: "" }; 
     }); 

je tente de fixer le info.plist sur IOS selon un autre poste (comme React Native fetch() Network Request Failed) mais l'erreur toujours là

iOS n'autorise pas les requêtes HTTP non sécurisées. Pour ce faire, vous devez ajouter votre domaine comme une exception dans votre info.plist.

Ajouter les éléments suivants:

<key>NSAppTransportSecurity</key> 
<dict> 
    <key>NSExceptionDomains</key> 
    <dict> 
    <key>yourserver.com</key> 
    <dict> 
     <!--Include to allow subdomains--> 
     <key>NSIncludesSubdomains</key> 
     <true/> 
     <!--Include to allow HTTP requests--> 
     <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key> 
     <true/> 
     <!--Include to specify minimum TLS version--> 
     <key>NSTemporaryExceptionMinimumTLSVersion</key> 
     <string>TLSv1.1</string> 
    </dict> 
    </dict> 
</dict>
