No signing certificate "iOS Distribution" found
Cause
Xcode can't find a distribution certificate with its private key in your keychain. Common after switching Macs, reinstalling macOS, or when a teammate created the certificate (the private key lives only on the machine that generated the CSR). Also appears when your Apple Developer membership has lapsed.
