maybe I find the answer about "Unable to send SI offer; the recipient doesn't have the required features"

[pengwj]

problem:Error Domain=XMPPOutgoingFileTransferErrorDomain Code=-1 "Unable to send SI offer; the recipient doesn't have the required features." UserInfo=0x15e59910 {NSLocalizedDescription=Unable to send SI offer; the recipient doesn't have the required features.}

I find the query will be null after [iq elementForName:@"query"] which in the method [- (void)handleRecipientDiscoInfoQueryIQ: withInfo:] .

Then I found in the method elementForName: (NSXMLElement+XMPP.m),robbiehanson write as so.

    // There is a bug in the NSXMLElement elementsForName: method.
    // Consider the following XML fragment:
    // 
    // <query xmlns="jabber:iq:private">
    //   <x xmlns="some:other:namespace"></x>
    // </query>
    // 
    // Calling [query elementsForName:@"x"] results in an empty array!
    // 
    // However, it will work properly if you use the following:
    // [query elementsForLocalName:@"x" URI:@"some:other:namespace"]
    // 
    // The trouble with this is that we may not always know the xmlns in advance,
    // so in this particular case there is no way to access the element without looping through the children.
    // 
    // This bug was submitted to apple on June 1st, 2007 and was classified as "serious".
    // 
    // --!!-- This bug does NOT exist in DDXML --!!--

so I replace the "NSXMLElement *query = [iq elementForName:@"query"]; " by

      NSXMLElement *query;
      NSArray *queryArray = [iq elementsForLocalName:@"query" URI:@"http://jabber.org/protocol/disco#info"];
      if (queryArray.count == 0) {
          query = nil;
      }
      else
      {
          query = queryArray[0];
      }

in XMPPOutgoingFileTransfer.m.

What is your target JID? is it full or bare?

[pengwj]

fullJID,with a resource

[yasiriqbal]

Try this! (This is in swift)

    self.xmppOutgoingFileTransfer.disableDirectTransfers = false
    self.xmppOutgoingFileTransfer.disableIBB = false
    self.xmppOutgoingFileTransfer.disableSOCKS5 = false

    self.xmppIncomingFileTransfer.disableDirectTransfers = false
    self.xmppIncomingFileTransfer.disableIBB = false
    self.xmppIncomingFileTransfer.disableSOCKS5 = false

i also met it,
i find the features need to contain some namespase like "http://jabber.org/protocol/si/profile/file-transfer", but there is nothing match it.
see my IQ:

<iq xmlns="jabber:client" type="result" to="c2@come.in/comein" id="A3EE5CF4-0758-438D-906C-0FA5908F02A6" from="c5@come.in/comein">
  <query xmlns="http://jabber.org/protocol/disco#info">
    <feature var="http://jabber.org/protocol/disco#info"/>
    <feature var="http://jabber.org/protocol/caps"/>
  </query>
</iq>

see method - (void)handleRecipientDiscoInfoQueryIQ: withInfo:
