RCKit

RoCry's personal Swift 6.2 + SwiftUI helpers for iOS/macOS projects. Tuist-first.

Swift 6.2 Approachable Concurrency

This project uses Swift 6.2's Approachable Concurrency features:

• SWIFT_APPROACHABLE_CONCURRENCY: YES - Enables SE-0461 (nonisolated async runs on caller's actor) and SE-0470 (infer isolated conformances)
• RCKit framework: nonisolated by default (appropriate for libraries)
• RCKitDemo app: MainActor by default via SWIFT_DEFAULT_ACTOR_ISOLATION (SE-0466)

Targets

• RCKit framework
• RCKitDemo app (SwiftUI demo)
• RCKitTests unit tests

Logging

import RCKit

// Create a logger alias (recommended pattern)
private let logger = Log.default

logger.info("message")
logger.debug("debug info")
logger.error("failed", metadata: ["code": 500])

// Or create custom logger with specific category
private let networkLogger = Log(category: "network")
networkLogger.info("request sent")

Output format: message (File.swift:42 functionName())

NSLogger (optional)

Streams logs to NSLogger desktop viewer via Bonjour.

Setup

1. Start NSLogger and bootstrap its Destination early in app launch:

let nsLogger = NSLoggerSupport.start(minimumLevel: .debug)
Log.bootstrap([nsLogger])

2. Add to Info.plist:

<key>NSBonjourServices</key>
<array><string>_nslogger._tcp</string></array>
<key>NSLocalNetworkUsageDescription</key>
<string>Discover NSLogger viewer on local network for live logging.</string>

Logs go to both OSLog and NSLogger simultaneously. Domain format: subsystem:category.

Options

• NSLoggerSupport.start(useBonjourForBuildUser: true) — returns a Destination using a per-user Bonjour service name
• NSLoggerSupport.start(useSSL: true) — returns a Destination using SSL

Notes

• Fail-fast: invalid inputs preconditionFailure
