Can we download a file directly into a connected external storage like a pendrive without downloading it into App Sandbox environment first and then copying the file to external storage, in case of larger files.

I need to programatically connect to a Enterprise Network with security type EAP-PEAP. NEHotspotEAPSettings *eapSettings = [[NEHotspotEAPSettings alloc] init]; eapSettings.username = username; eapSettings.password = password; eapSettings.supportedEAPTypes = [NSArray arrayWithObjects:[NSNumber numberWithInteger:NEHotspotConfigurationEAPTypeEAPPEAP], nil]; //Inner authentication eapSettings.ttlsInnerAuthenticationType = NEHotspotConfigurationEAPTTLSInnerAuthenticationMSCHAPv2; eapSettings.outerIdentity = @""; //Server name of the network eapSettings.trustedServerNames = @[@"servername"]; if (@available(iOS 11.0, *)) { // Create Hotspot Configuration NEHotspotConfiguration *configuration = [[NEHotspotConfiguration alloc] initWithSSID:ssid eapSettings:eapSettings]; NSLog(@"WIFIManager, NEHotspotConfiguration initialized"); [[NEHotspotConfigurationManager sharedManager] applyConfiguration:configuration completionHandler:^(NSError * _Nullable error) { NSLog(@"WIFIManager, NEHotspotConfiguration Configured"); if (error != nil) { NSLog(@"WIFIManager, NEHotspotConfiguration Error: %@", error); if (error.code == NEHotspotConfigurationErrorAlreadyAssociated) { resolve(@(YES)); } else { reject(@"connection_error", @"Failed to connect to Wi-Fi", error); } } else { resolve(@(YES)); NSLog(@"WIFIManager, NEHotspotConfiguration Success"); } }]; }else { reject(@"ios_error", @"Not supported in iOS<11.0", nil); } } This is the code I have tried to connect to the network. It is always giving a true-negative result. As the documentation states, does NEHotspotConfigurationManager supports EAP-PEAP with MSCHAPv2 inner authentication? If it does, is it the correct way of implementing it? Is there any other way to connect to EAP-PEAP networks using Swift or Objective C?
