Just upgraded to Xcode 8b2 and launched an app I've been working on and got this erro:

[OSStatus] error:[-34018] Error Domain=NSOSStatusErrorDomain Code=-34018 "client has neither application-identifier nor keychain-access-groups entitlements" UserInfo={NSDescription=client has neither application-identifier nor keychain-access-groups entitlements}

Sounds just like https://forums.developer.apple.com/thread/4743 from last year. Seems like for now my app is unable to access the Keychain at all, at least in the simulator. Works fine when I run it on a device. Anyone else seeing this with iOS 10?

I noticed this myself this morning... The workaround I found is to just enabled Keychain Sharing.

  That does indeed work around the problem, though it's not the "correct solution", of course. Will file a radar.

    Filed rdar://27196346 with this code, which replicates the issue:
    
    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { NSDictionary *query = @{ (__bridge id)kSecClass: (__bridge id)kSecClassGenericPassword, (__bridge id)kSecAttrService: @"SomeAttrService", (__bridge id)kSecAttrAccount: @"SomeAccount", (__bridge id)kSecAttrGeneric: @"SomeGeneric", (__bridge id)kSecValueData: [@"SomeValue" dataUsingEncoding:NSUTF8StringEncoding], (__bridge id)kSecAttrAccessible: (__bridge id)kSecAttrAccessibleAfterFirstUnlock, }; OSStatus status = SecItemAdd((__bridge CFDictionaryRef)query, NULL); if (status != errSecSuccess) { NSLog(@"Error saving key: %i", (int)status); } return YES; }

      Did you get a reply? The issue only seems to happen to me when I run unit tests. Enabling shared keychain and running on actual app is working on fine (on simulator).

      I'm seeing this as well from betas 2 through 6. Enabling keychain sharing entitlement works around the issue. Filed a radar. rdar://27867529

        I've also been seeing this issue in the same set of betas you have and reported it as a bug #27829053 (XCUITest run in Xcode Server Bot hangs when uploading screenshots.). However, I'm trying to test keychain API calls in a Cocoa Touch Framework with unit tests, and probably can't use the "Keychain sharing" workaround that seems to work for others. Any ideas? Thanks!

        We are seeing the same issue in our test targets. We have a Keychain wrapper that we have a bunch of tests around that all pass on macOS and tvOS, but all fail on iOS due to the -38014 error being continuously returned from the `SecItemAdd` API. I just filed rdar://28117856 which I'm assuming will be closed out as a duplicate. I'm really hoping Apple gets this fixed before the GM.

Happening to me too on iOS10 simulator, XCode8 Beta 6. Keychain sharing is enabled, but it didn't help. I couldn't find any way around this, only using actual device helps.

same for me as well. iOS 10 device working nicely, only simulator has problems.

sanityCheck = SecKeyGeneratePair((__bridge CFDictionaryRef)keyPairAttr, &publicKeyRef, &privateKeyRef);

I found something interesting...

As others have reported, my app would always fail on SecItemAdd() with -34018 on the simulator but work fine on a device. I was about to add the 'Share keychain' entitlement as a workaround but noticed that Xcode 8 was prompting me to add the 'Push Notification' entitlement (that entitlement is now required to use push notificaitons on iOS 10 as the permission is taken from the entitlement rather than the provisioning profile in earlier versions). This *created* an entitlements file because the app didn't have one before. And without adding the 'Share keychain' entitlement the app suddenly started working! No more -34018. I've reverted back and forth and it seems pretty deterministic: no entitlements file gives -34018; entitlements file works.

So, my testing seems to show that SecItemAdd fails if there's no entitlement file, and works if there is one! Perhaps all the developers adding 'Share keychain' entitlement never had an entitlement file before and it is the creation of the file rather than the specific entitlement that fixes the problem?

Yesterday I had same problem -34018 error in keyChain class. Xcode Version 8.0 (8A218a), iOS 10.
I solved this problem by downloading iOS 9.3 simulator. Now I simply start simulator with iOS 9.3 and the error disappears. I’ll wait until Apple solves this problem and only then I am going to start using iOS 10 Simulator.

      In my earlier comment I found just adding an entitlements file fixed the problem. it doesn't seem to matter what the entitlement is. I've not tried creating a plist with no actual entitlements, but even an "empty" file might work (it's not literally an empty file because it has the plist xml structure, but it would have no actual entitlements inside).

        be careful of side effects of enabling push notifications. You might get problems submitting the app for review or at runtime in production builds. I was able to add that entitlement for my app because I really do use push notifications.

It don't work with enabling Keychain sharing. Is there anyone encounter problem like me?
