Example Implementation

https://github.com/tinfoilanalytics/verifier-swift-example

Installation

Using Swift Package Manager

1. In Xcode, select File > Add Package Dependencies
2. Enter the package repository URL:

   https://github.com/tinfoilanalytics/verifier-swift
   

3. Select the version you want to use
4. Click "Add Package"

Alternatively, you can add it directly to your Package.swift file:

dependencies: [
    .package(url: "https://github.com/tinfoilanalytics/verifier-swift", exact: "0.0.2")
]

Basic Usage

Importing the Package

First, import the TinfoilVerifier package in your Swift file:

import TinfoilVerifier

Creating a Verifier Client

To create a new verifier client:

let client = TinfoilVerifier.ClientNewSecureClient(
    "inference-enclave.tinfoil.sh",               // Enclave hostname
    "tinfoilanalytics/nitro-enclave-build-demo"   // Repository path
)

Performing Verification

To verify an enclave:

do {
    let enclaveState = try client?.verify()

    // Access EIF hash and TLS certificate fingerprint
    let eifHash = enclaveState?.eifHash
    let certFingerprint = enclaveState?.certFingerprint
} catch {
    print("Verification failed: \(error)")
}
