Update: This issue has been fixed in Xcode 8.2. Keychain works in the simulator without enabling keychain sharing.
Why am I always receiving error -34018 when calling SecItemAdd function in Xcode 8 / iOS 10 simulator?
Steps to Reproduce
Create a new Single page iOS app project in Xcode 8.
Run the following code in viewDidLoad (or open this Xcode project).
let itemKey = "My key"
let itemValue = "My secretive bee 🐝"
// Remove from Keychain
// ----------------
let queryDelete: [String: AnyObject] = [
kSecClass as String: kSecClassGenericPassword,
kSecAttrAccount as String: itemKey as AnyObject
]
let resultCodeDelete = SecItemDelete(queryDelete as CFDictionary)
if resultCodeDelete != noErr {
print("Error deleting from Keychain: \(resultCodeDelete)")
}
// Add to keychain
// ----------------
guard let valueData = itemValue.data(using: String.Encoding.utf8) else {
print("🐣🐣🐣🐣🐣🐣🐣🐣🐣🐣 Error saving text to Keychain")
return
}
let queryAdd: [String: AnyObject] = [
kSecClass as String: kSecClassGenericPassword,
kSecAttrAccount as String: itemKey as AnyObject,
kSecValueData as String: valueData as AnyObject,
kSecAttrAccessible as String: kSecAttrAccessibleWhenUnlocked
]
let resultCode = SecItemAdd(queryAdd as CFDictionary, nil)
if resultCode != noErr {
print("🐝🐝🐝🐝🐝🐝🐝🐝🐝 Error saving to Keychain: \(resultCode).")
} else {
print("🍀🍀🍀🍀🍀🍀🍀🍀🍀 Saved to keychain successfully.")
}
Expected Results
Item is added to Keychain.
Actual Results
Function SecItemAdd returns the following error code: -34018.
Version
Xcode version 8.1 (8B62), macOS Sierra 10.12.1.
Configuration
Always occurs in Xcode 8 since Beta 2 when testing in an iOS 10 simulator.
Does NOT occur in Xcode 8 when testing in an iOS 9.3 simulator.

This issue is different from the following post because it occurs consistently in Xcode 8. SecItemAdd and SecItemCopyMatching returns error code -34018 (errSecMissingEntitlement)SecItemAdd and SecItemCopyMatching returns error code -34018 (errSecMissingEntitlement)
