Submitting apps to the App Store using Xcode
If you’re an Apple Developer Program member, Xcode provides an integrated workflow to prepare and submit apps to App Store. You should use the latest version of Xcode available on the Mac App Store to submit your apps, or when available, the latest GM seed release from the Downloads page.
Do not submit apps built using beta software, as beta versions of Xcode, Operating Systems, and SDKs are for development and testing only.

Providing feedback and reporting bugs
Your feedback goes a long way towards making Xcode even better. With Feedback Assistant, you can report issues or request enhancements to APIs and tools.

Invalid private key and certificate pairing
If you received an error message saying, 'Xcode could not find a valid private-key/certificate pair for this profile in your keychain.' This error message indicates that the Keychain Access application on your Mac is missing either the public or private key for the certificate you are using to sign your app.
Mac Preview User Manual
This often happens when you are trying to sign and build your app from a different Mac than the one you originally used to request your code signing certificate. It can also happen if your certificate has expired or has been revoked. Ensure that your app’s provisioning profile contains a valid code signing certificate, and that the Keychain Access application on your Mac contains that certificate, the private key originally used to generate that certificate, and the WWDR Intermediate Certificate.
For instructions on how to resolve this and other code signing errors, review the Code Signing Support page.

Hello everyone,
Mac Preview User Manual Download
I have a huge problem with Mac preview in combination with a Network Attached Storage NAS system. Everytime my NAS is offline or I'm not at home and I start Mac preview it crashes totally. Reason for this is that the Preview program tries to look for something (not sure what it is) on the NAS ... but the file is not online .... and sadly then preview crashes.
Mac Preview User Manual Pdf
I'm quiet sure that I just have to bring the preview program back to its default setting. There must be some folder that I have to delete (and these are then automatically renewed on next start of preview) and then everything will work fine again (it worked fine for more than one year with the NAS already)
I really need help on this topic.
Thanks for helpful answers guys.
Best Regards,
