Secure Enclave Swift

This project shows you how to

• create a keypair where as the private key is stored in the secure enclave
• sign a string / some data with the private key
• use the security functions like SecKeyRawVerify, SecKeyGeneratePair and SecItemCopyMatching in Swift 3
• store the public key in the keychain

The keypair uses Elliptic curve algorithm (secp256r1) with PKCS1 padding.

It was a bit tricky to find out how to do all this in Swift 3, so here it is :)
