#import <SOAPEngine/SOAPEngine.h>

SOAPEngine *soap = [[SOAPEngine alloc] init];
soap.userAgent = @"SOAPEngine";
soap.delegate = self; // use SOAPEngineDelegate
[soap setValue:@"my-value1" forKey:@"Param1"];
[soap setIntegerValue:1234 forKey:@"Param2"];
[soap requestURL:@"http://www.my-web.com/my-service.asmx" soapAction:@"http://www.my-web.com/My-Method-name"];
#pragma mark - SOAPEngine delegates
- (void)soapEngine:(SOAPEngine *)soapEngine didFinishLoading:(NSString *)stringXML {
        NSDictionary *result = [soapEngine dictionaryValue];
        // read data from a dataset table
        NSArray *list = [result valueForKeyPath:@"NewDataSet.Table"];
}

I'm trying to call a method with "call" SoapAction, so I need to pass an Array forKey "args". Unfortunately soap.setValue( myArray, forKey: "args") does not work
PS: I use Swift language

could someone please help me?
