ios – Including certificates to gadget keychain

I’m attempting to import a certificates to the gadget keychain, which I get my API. I’ve used these references to save lots of acquired information in certificates format. references: (SecPKCS12Import returns totally different outcomes on iOS 11 than on iOS 10)
and Add Certificates to IOS Keychain in Swift
By doing a little modifications so as to add the certificates to the keychain I’ve accomplished under code:

 ` func certificateFromCertificate(certP12: Knowledge, psswd: String) {
        let decodedData =  certP12
        
        let keytmp : NSString = kSecImportExportPassphrase as NSString
        let choices : NSDictionary = [keytmp : psswd]
        
        var certificateRef: SecCertificate? = nil
        
        var gadgets : CFArray?
        
        let securityError: OSStatus = SecPKCS12Import(decodedData as CFData, choices, &gadgets)
        
        let theArray: CFArray = gadgets!
        if securityError == noErr && CFArrayGetCount(theArray) > 0 {
            let newArray = theArray as [AnyObject] as NSArray
            let dictionary = newArray.object(at: 0)
            let secIdentity = (dictionary as AnyObject)[kSecImportItemIdentity as String] as! SecIdentity
            let securityError = SecIdentityCopyCertificate(secIdentity , &certificateRef)
            if securityError != noErr {
                certificateRef = nil
            }
        }
        
                var keychainQueryDictionary = [String : Any]()

                if let tempSecCert = certificateRef {
                    keychainQueryDictionary = [kSecClass as String : kSecClassCertificate, kSecValueRef as String : tempSecCert, kSecAttrLabel as String: "My Certificate"]
                }

                let abstract =  SecCertificateCopySubjectSummary(certificateRef!)!  as String
                print("Cert abstract: (abstract)")

                let standing = SecItemAdd(keychainQueryDictionary as CFDictionary, nil)

            print(SecCopyErrorMessageString(standing, nil))

    }`

I get correct certificates abstract and likewise this print(SecCopyErrorMessageString(standing, nil))
is returning no error. Non-obligatory(No error.)

The doubt I’ve is whether or not this certificates is correctly put in within the gadget keychain or not. How do I confirm that? Please notice I do not wish to belief the certificates forcefully.

I attempted

var keychainQueryDictionary = [String : Any]()
    
if let tempSecCert = certificateRef {
  keychainQueryDictionary = [kSecClass as String : kSecClassCertificate, kSecValueRef as String : tempSecCert, kSecAttrLabel as String: "My Certificate"]
}
    
let abstract =  SecCertificateCopySubjectSummary(certificateRef!)!  as String
print("Cert abstract: (abstract)")
    
let standing = SecItemAdd(keychainQueryDictionary as CFDictionary, nil)

This may import the certificates to the keychain of the gadget. I wish to confirm whether it is put in efficiently.
