IOS React Native fetch() POST : Network Request Failed - react-native

Question

1) The following code give me an error on IOS but work on Android.
2) On IOS i Can make fetch with "get" but "post" fails
so this don't work on 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: "" };
});
i try to fix the info.plist on IOS according to other post (like React Native fetch() Network Request Failed) but the error still there

iOS does not allow insecure HTTP requests. In order to do so, you have to add your domain as an exception inside your info.plist.
Add the following:
<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>
