I'm using Xamarin.Auth (https://components.xamarin.com/view/xamarin.auth/) to store my credentials, as I've always done.
var accountStore = AccountStore.Create (); foreach (var account in accountStore.FindAccountsForService("myAppName")) accountStore.Delete (account, "myAppName"); AccountStore.Create().Save(acc, "myAppName");
After the upgrade to iOS 10 I get this error storing credentials:
"Could not save account to KeyChain: -34018" at Xamarin.Auth.KeyChainAccountStore.Save (Xamarin.Auth.Account account,System.String serviceId) [0x000b2] in <402cf9b3716845b3bdddef581cb33a3e>:0
Latest version installed 1.2.3.1 The problem seems to persist only on the SIMULATOR
I was digging through the link Pat sent in the comment: bugzilla.xamarin.com/show_bug.cgi?id=43514
And found a helpfull comment by Pavel Sich, he said:
Just make sure you enable the keychain access in Entitlements and select the entitlements for Simulator (Debug) builds too. By default this is not set.
In my xamarin solution, I double clicked the .IOS project to open the options pane, selected IOS Bundle Signing and changed the Platform select box from "iPhone" to "iPhoneSimulator", then set the field Custom Entitlements to my Entitlements.plist. Now it's working fine for me.
Just a note, this is after editing the Entitlement.plist as suggested by Thibault D. in the previous answer.
Hope this helps.
According to this thread it's enough that you add an empty entitlements file in you bundle singing configuration:
<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|iPhoneSimulator' "> ... <CodesignEntitlements>Entitlements.plist</CodesignEntitlements> </PropertyGroup>
Empty Entitlements.plist
file:
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> </dict> </plist>
