I have a NSURLconnection implementation and am trying to migrate to NSURlsession for IOS-9.
NSURLconnection implementation:
@property (nonatomic, strong, readwrite) NSURLConnection * connection;
Custom delegate methods:
-(BOOL)connection:(NSURLConnection *)connection ---canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace*)protectionSpace
-(void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
- (void)connection:(NSURLConnection *)conn didReceiveResponse:(NSURLResponse *)aresponse
-(void)connection:(NSURLConnection *)conn didReceiveData:(NSData *)data
- (void)connectionDidFinishLoading:(NSURLConnection *)conn
- (void)connection:(NSURLConnection *)theConnection didFailWithError:(NSError*)error
self.connection = [NSURLConnection connectionWithRequest:request delegate:self];
Now when i modified the above impl to NSURLsession based impl, i now have
@property (nonatomic, strong, readwrite) NSURLSession *session;
Custom delegate Method :
- (BOOL)URLSession:(NSURLSession *)session task:(NSURLSessionTask *)task canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace*)protectionSpace
- (void)URLSession:(NSURLSession *)session task:(NSURLSessionTask *)task didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
- (void)URLSession:(NSURLSession *)session task:(NSURLSessionTask *)task didReceiveResponse:(NSURLResponse *)aresponse
- (void)URLSession:(NSURLSession *)session task:(NSURLSessionTask *)task didReceiveData:(NSData *)data
- (void)URLSession:(NSURLSession *)session task:(NSURLSessionTask *)task connectionDidFinishLoading:(NSURLConnection *)conn
- (void)URLSession:(NSURLSession *)session task:(NSURLSessionTask *)task didFailWithError:(NSError *)error
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
self.session = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue: nil];
NSURLSessionDataTask *task = [self.session dataTaskWithRequest:request];
[task resume];
After this , i am getting compilation error as below:
./../source/smmacosx/smplt.m:663:33: error: sending 'SmHttpsAuthenticationHandler *' to parameter of incompatible type 'id<NSURLSessionDelegate> _Nullable' [-Werror]

I am not able to understand why delegate=self in NSURLSession Impl is throwing such an error? SmHttpsAuthenticationHandler is an interface defined as
@interface SmHttpsAuthenticationHandler: NSObject{....} and then @implementation SmHttpsAuthenticationHandler
Please help.Please give any pointers on NSURLSession implementation. Thanks a lot.
