I am trying Google Cloud Messaging sample app for iOS platform. https://developers.google.com/cloud-messaging/ios/start

To generate GoogleServices-Info.plist APNS development and production certificates are needed (PKCS#12 file format). I have created .p12 file in MAC KeyChain Access (bundling both APNS dev certificate and private key).

But when uploading the .p12 file, it says it is not in valid format (The certificate must be a valid PKCS12 file).

Here's my solution, without the terminal !

  • delete your actual certificate ( in Keychain ) : "Apple Development IOS Push Service" & "Apple Production IOS Push Service"

  • Go to Apple Developer, Identifiers, App IDs, Select "YourApp", Edit, Push Notification and download the 2 certificates (dev & prod)

  • import these 2 certificates in Keychain

  • in Keychain, go to "My Certificates", find the "Apple Development IOS Push Service" & "Apple Production IOS Push Service", click on the arrow to expand the Certificate + Key

  • Select both the the Certificate + Key, Right click "Export 2 items", you have your .p12 valid certificate ready for upload to GCM Services
