iOS Game · On the App Store

A 2.5D neon stacking game for iOS, and a case study in hardware-backed API security.

Time a sliding disc and stack it; miss the centre and the overhang is sliced away. Two coupled difficulty dials produce 25 distinct modes, each keeping its own personal best, with a global leaderboard that weights every setting by how hard it genuinely plays.

• Apple App Attest verified end-to-end — the Cloudflare Worker decodes the CBOR attestation, walks the X.509 chain to Apple's pinned root CA, and checks a single-use server challenge
• Keys are generated inside the Secure Enclave, so no secret ships in the binary
• Config responses are AES-256-GCM encrypted; requests carry an HMAC-SHA256 signature with a freshness window
• Remote configuration and release gating operated from a Cloudflare Worker

Swift Package · Apple-platform networking

A batteries-included Swift package for building Xray-powered VPNs on iOS and macOS.

Building a VPN on Apple platforms normally means gluing together a static Go library, an NEPacketTunnelProvider, a hand-rolled packet bridge, geo-file management and a fragile memory budget — then discovering the Network Extension gets killed under load. MXray packages all of that into one dependency.

• XrayPacketTunnelProvider — a ready NEPacketTunnelProvider base class to subclass
• XrayBridge — the low-level NEPacketTunnelFlow ↔ gVisor tun engine, batched packet I/O
• Tuning presets with a Go heap ceiling matched to the Network Extension memory limit
• Share-link parsing (vless, vmess, trojan, ss), async geo-file loading, latency ping
• Companion repository libXray-apple provides the memory-tuned xcframework build

Swift Package · Device security

Prove your requests come from your real app — with a key that cannot be extracted.

The usual way a server recognises its own app is a secret compiled into the binary, and that does not survive a disassembler. App Attest answers it properly with a key generated inside the Secure Enclave. The flow is fiddly, and this package handles it — including the failure modes that only surface in production.

• Zero dependencies, Swift Package Manager compatible
• Secure Enclave request signing with one-time challenges and per-request assertions
• Handles key regeneration after restore or reinstall, assertion counter drift and attestation rejection
• Continuous integration running on every push

iOS App · SwiftUI

A SwiftUI exam-score calculator that handles negative marking and charts progress over time.

Enter the number of correct, incorrect and unanswered questions, choose whether the exam applies a negative penalty, and get a percentage, a plain-language verdict and a chart of how results have moved.

• Both marking schemes, with and without the negative penalty
• Score history rendered with Swift Charts
• Interface built entirely in SwiftUI, laid out right-to-left
• Appearance and preferences persisted with @AppStorage
