Is there a step by step program on Sending Push notifications? I seem to be stuck at load private key. I get this error. SecKeyCreateWithData failed with error: Error Domain=NSOSStatusErrorDomain Code=-50 "EC private key creation from data failed" It is a new p8 file. I tried different format. I read some articles that say that there is a bug I think. I don't know for sure because it was written in jibberish. 90% of the code is dealing with these stupid keys. This should be 1 function setting the pipe and then I can use the pipe. This is ridiculous. If anybody has any ideas. The code is a mess because I tried so many different ideas. Push Notification.txt
