# `noir_swift`: Swift-based zkSNARK Proving&Verifying tool for noir-lang
Welcome to Swift-Bridge, a seamless connector between the Swift programming ecosystem and the `noir_rs` Rust library. This bridge is designed to provide Swift developers with easy and efficient access to `noir_rs`'s zkSNARK proving functionalities, making it highly applicable in iOS, macOS, WatchOS, and other platforms that support Swift.
- 
## Key Highlights:
- **Swift Integration**: Custom-built for Swift developers, enabling native access to zkSNARK tools within the Swift environment.
- **Rust-Swift Bridge**: Offers a fluid connection between Swift and Rust, providing a smooth and efficient integration.
- **Security Focused**: Ensures top-notch security with advanced zkSNARK proof generation and verification capabilities, integral for privacy and scalability in computing.
## Building & Testing Instructions:
### Building Rust Components:
```bash
cargo build
```
### Testing Rust Components:
For high confidence in the bridge's reliability, utilize the included test suites:
```bash
cargo test
```
### Building Swift Components:
```bash
# Transfer noir_swift library to Swift directory
cp target/debug/libnoir_swift.a swift/
cd swift
# Compile Swift project
./build
# Execute the program
./main.run
```
## Usage:
Swift-Bridge mainly provides two crucial functions:
1. **Prove in Swift**: Create a zkSNARK proof using provided circuit bytecode and initial witness.
2. **Verify in Swift**: Authenticate a zkSNARK proof against its respective circuit and verification key.
```rust
struct Proof {
proof: Vec,
verification_key: Vec,
}
fn prove_swift(circuit_bytecode: String, initial_witness_vec_raw: Vec) -> Option;
fn verify_swift(circuit_bytecode: String, proof: Proof) -> Option;
```
## Example:
Here's an example using a noir circuit to verify if x is different from y:
```swift
let BYTECODE = ""
let witness = RustVec()
witness.push(value: 1) // x value
witness.push(value: 2) // y value
guard let proof = prove_swift(BYTECODE, witness) else {
return false
}
let verdict = verify_swift(BYTECODE, proof) ?? false
print(verdict) // Outputs true if successful verification
```
## Future Developments:
We are constantly working to improve the Swift-Bridge, focusing on enhancing its compatibility with a broader range of Swift-supported platforms and streamlining its integration into Swift-based projects.
Stay tuned for more updates and advancements in bridging Swift with the world of zkSNARKs!
