Hi,

i added a podspec File to use your Library with Cocoapods (only if you use the swift-branch of Cocoapods like described here http://swiftwala.com/cocoapods-is-ready-for-swift/) But its not workin, i can install your Library with "bundle exec pod install" if defined in my Podfile, but i cant use it because a framework class/module called "KeychainWrapper" allready exists.

Hey,

So I have done some more testing with your updated version and its not saving data anymore.

It returns a successful bool on the set method but on next launch all data is gone again. So ...object(forKey: ...) doesnt work anymore.

Have you made any changes because when I upgraded the project to swift 3 myself I did not have that problem.

Whats going on?

Flexibility could be provided by supporting the other possible values (internet password, certificate, key, identity). An enum could be used to wrap the CFString constant values and the KeychainWrapper public methods could either be overloaded or take an optional parameter.

To take this even further, an "options" type could be used as a parameter to wrap the SecClass and any other useful options, such as whether the device must be unlocked for access and whether TouchID is needed to retrieve the item.

I've begun implementation of these features in my own fork and can provide samples (or a pull request) if you're open to these ideas.

Hi there,

My code has been working fine until now, suddenly these lines returns false:

let ops: Bool = KeychainWrapper.defaultKeychainWrapper.set(ops, forKey: "ops")
let jop: Bool = KeychainWrapper.defaultKeychainWrapper.set(jop, forKey: "jop")

I use cocoapods, and this in the Podfile:

pod 'SwiftKeychainWrapper', :git => 'https://github.com/jrendel/SwiftKeychainWrapper.git', :branch => 'master'

Any ideas?

The current version (2.2.0) has not been updated on cocoapods (https://cocoapods.org/pods/SwiftKeychainWrapper) and cannot be installed using pods for now. Please update the version from 2.0 to 2.2 over there.

Haven't fully investigated but there is a rather odd bug with this Wrapper. Some phones will save to keychain using SwiftKeychainWrapper, others will not. There is no correlation between phones or versions, some iPhones 5s's the wrapper works, other it does not. This applies to all devices - 6, 6 plus, 4s.

To further describe - Saving to keychain in our test group worked for an iPhone 5s on 8.1.3 - on another 5s on 8.1.3 it did not. One iPhone 6 it did not work for (also on 8.1.3), on an iPhone 5 on 8.1.2 it did work.

Bug is also not related to settings or anything related to settings within said app, it is isolated to SwiftKeychainWrapper.

When packaging up a release IPA (IE: for testflight) KeychainWrapper.stringForKey() returns a nil value. It passes without error, but the value is blank.

For instance:

KeychainWrapper.setString("APPLE", forKey: "FRUIT")
var fruit = KeychainWrapper.stringForKey("FRUIT")
var alert:UIAlertView = UIAlertView(title: "FRUIT", message: "\(fruit)", delegate: self, cancelButtonTitle: "Ok")
alert.show()

Took a lot of searching, but I stumbled across: http://stackoverflow.com/questions/26355630/swift-keychain-and-provisioning-profiles

Disabling the optimizations for the release target remedied the problem, but I am wondering if there is something that can be done to fix whatever is breaking when optimized away. (Might just have to wait for an apple fix?)

Hi @jrendel , I have a problem with saving values to Keychain, below is the line I'm using, and it always returns false in xCode8 and Swift2.3 (I can't use Swift 3 at the moment because some other frameworks are not updated) Just to mention, it all worked with xCode7 and Swift2.2 on iOS9.3 simulator, but now I'm using iOS10 simulator, maybe this could be the issue? (downloading 9.3 simulators at the moment)

let isSaveSuccessfulToken: Bool = KeychainWrapper.defaultKeychainWrapper().setString(token, forKey: "token")

I'm using Carthage and I tried with the following
github "jrendel/SwiftKeychainWrapper" github "jrendel/SwiftKeychainWrapper" "master" github "jrendel/SwiftKeychainWrapper" == 2.1.0 github "jrendel/SwiftKeychainWrapper" "Swift2.3"

all compiled to Swift2.3 using carthage update --platform iOS --toolchain com.apple.dt.toolchain.Swift_2_3 SwiftKeychainWrapper which builds successfully (also used with some other frameworks that work now)

Tnx

I'm getting some strange behavior when accessing data. I have a static method that I use to retrieve a stored auth token for an API call. This static method is called a couple times and returns the data I expect. From one of my view controllers though it's returning nil.

I make the exact same call for the exact same keys. Two calls return data and the last one does not. I'm getting a return status of -34018. I'm not sure what that error code is.

First, congrats for the wrapper. Simple and efficient.

I just missed out one function: a removeAllKeys() function that would erase all Keychain items. That is very useful to clean the Keychain on the app first run.

How can this be a Swift rewrite when you're still using the main ObjC method inside of it. return KeychainObjcWrapper.dataForDictionary(keychainQueryDictionary)

The query dict passed to SecItemDelete in removeAllKeys does not contain any value for the synchronizable attribute, so it actually defaults to false, deleting only those items that are false, and leaving out items that were saved with true. The same also applies with the wipeKeychain method. We should add a value for sync to specify any.

From the documentation on the sync attribute:

If the key is not supplied, or has a value of kCFBooleanFalse, then no synchronizable items are added or returned. Use kSecAttrSynchronizableAny to query for both synchronizable and non-synchronizable results.

I had saved apple identifier and its hidden email in Keychain using other utility. Now while trying to fetch using this library, I am able to get apple identifier, but that email address is not retrieving. Used data and string format to fetch and data is also 0 bytes.

I am testing my app on my phone via Xcode 13.3.1.

I removeAllKeys upon launch, then set a new integer value for a consumable product.

KeychainWrapper.standard.integer(forKey: productIdentifier) ?? 0

1. This value is zero (0) when I first read it.
2. I read it, increment it by one and save it. Then read it again. It reads 2 instead of 1.
3. If I repeat step 2, I still get 2.

Rebooting the phone changed nothing.

Does anybody experience something similar?

Hi, I try save string data on keychain, however, the function set return False.

Any idea ?

I post the code:

    public static var tokenSession: String {
        set {
            KeychainWrapper.standard.set(
                newValue,
                forKey: "sm_token_session_key",
                withAccessibility: .always,
                isSynchronizable: true
            )
        }
        get {
            KeychainWrapper.standard.string(
                forKey: "sm_token_session_key",
                withAccessibility: .always,
                isSynchronizable: true
            ) ?? .empty
        }
    }

I've noticed, that if i store something and immediately retrieve from other function, it not manage to return appropriate value.

Hi! Thanks a lot for such a great library!

I would like to see if there could be an integration with Swift Combine which would allow getting updates to the Keychain reactively as a stream of changes when they happen. What is the feasibility of that?

Any other way to expose callback when a change happens like KVO, Notification or delegate would also be a great start.
