Indicates whether a trust evaluation is permitted to fetch missing intermediate certificates from the network.


func SecTrustGetNetworkFetchAllowed(_ trust: SecTrust, _ allowFetch: UnsafeMutablePointer<DarwinBoolean>) -> OSStatus



The trust evaluation object to query.


A pointer to a Boolean that the function sets to true to indicate that the trust evaluation process is permitted to download missing certificates from the network, or false otherwise.

Return Value


By default, network fetch of missing certificates is enabled if the trust evaluation includes the SSL policy. Otherwise it is disabled.
