Unable to access keychain from Unwanted Communication Extension iOS










1















I am creating Unwanted Communication Extension extension for my app, But when i try to access the keychain for login details, it is not able to access the keychain.



Note: Entitlements with keychain sharing is added and keychain sharing is on for my app.



I tried using this code on my extension view controller and it returns error code -25291 on SecItemCopyMatching



let queryLoad: [String: AnyObject] = [
kSecClass as String: kSecClassGenericPassword,
kSecAttrAccount as String: itemKey as AnyObject,
kSecReturnData as String: kCFBooleanTrue,
kSecMatchLimit as String: kSecMatchLimitOne,
kSecAttrAccessGroup as String: keychainAccessGroupName as AnyObject
]

var result: AnyObject?

let resultCodeLoad = withUnsafeMutablePointer(to: &result)
SecItemCopyMatching(queryLoad as CFDictionary, UnsafeMutablePointer($0))


if resultCodeLoad == noErr
if let result = result as? Data,
let keyValue = NSString(data: result,
encoding: String.Encoding.utf8.rawValue) as? String

// Found successfully
print(keyValue)

else
print("Error loading from Keychain: (resultCodeLoad)")
