KeychainItemWrapper 'Couldn't add the Keychain Item.'

Question

I want to store access token to keychain. But i got the error: Couldn't add the Keychain Item.'

I checked some posts on stackoverflow like: Storing email in keychain impossible (KeychainItemWrapper)

MyCode:

let a = NSKeyedArchiver.archivedData(withRootObject: "980a872c17a075367357e25e88c1c0476417092a")
let keyWrapper = KeychainItemWrapper.init(identifier: "23123123", accessGroup: nil)
keyWrapper?.setObject(a, forKey: kSecValueData)

I tried add this

keyWrapper?.setObject(kSecAttrAccessible, forKey: kSecAttrAccessible)

Change kSecValueData to kSecAttrGeneric

I am running Xcode 8 with swift 3.0. Any hints thank you!

I have recently face this issue with Xcode 8.

To solve the issue You have to add the "Share keychain entitlement" to Xcode capabilities.

There are many users who faced this issue.

Hi Viruss, it's interesting. This just work for me once. I enabled it. And still same error now. I tried to add KeyChain Groups string into accessGroup parameter, still no help. Any idea?

I only see this error in my simulator, on iOS 10 devices it runs fine. I'm very confused.

The other answer about the Entitlements should really be the accepted answer.

Hi @KennyWyland i knew Viruss did provide a good solution, but it doesn't really solve my problem. I have up voted for this answer. Thank you!

It didn't solve your problem, but was the reason for it, from the answers provided, was the best one
