PCLCrypto: Problem Import Public Key in IOS 10

My App in Xamarin IOS there is this exception during ImportPublicKey:

Stack:

I ran across this, too. Seems to be an Xcode issue at the root. Finally found a simple workaround with Xamarin tooling:

Ensure Entitlements.plist exists in project.
Enter “Entitlements.plist” in iOS Bundle Signing -> Custom Entitlements.

With that I was able to get @leastprivilege’s iOSClient sample running on iOS 10 simulator.

Just to supplement @gregfiske’s comment - I was getting the same exception, and the issue was appearing on iOS 10 Simulator.

System.InvalidOperationException: SecItemAdd return -34018 ... at PCLCrypto.RsaAsymmetricKeyAlgorithmProvider.ImportPublicKey

By adding entitlements to iOS Bundle Signing as @gregfiske recommended (yes, even for debug & release and for simulator), the issue was resolved. Just ensure you have corresponding signing identity and provisioning profile for your bundle ID.
