Convenience

This is a little holding place for common tools and conveniences that I like to use in my personal projects.

If anyone ever finds and uses this, I'd love to hear any feedback.

Contents:

• Extensions:
  • OSLog.Logger:
    • init(_:), which uses the process name and bundle name for the logger's subsystem, and the provided string for the category.
  • Int:
    • of<Value>(_ value: @autoclosure () throws -> Value) rethrows -> [Value]): fills an array with self values by executing the provided closure self times.
    • times(_ execute: @autoclosure () throws -> Void) rethrows: executes the provided closure self times.
  • String:
    • randomTitle(wordCount:): generates a randomized Title Case string a specified number of words long.
  • Calendar:
    • days(from:to:): computes a distance, in days, between two dates. Accounts for partial days.
    • cardinalComponents(from:to:) computes a distance, in years, months, and days, between two dates. Accounts for partial days.
  • Result: *static func success(): a wrapper for the uglier .success(())
• Tools:
  • Keychain: A simplistic wrapper for storing single String values into the user's keychain. Uses the kSecClassGenericPassword item class.
• Property wrappers:
  • KeychainStorage: A property wrapper that uses the Keychain convenience to wrap properties that use the user's keychain for their storage.
  • ReadersWriterLocked: A property wrapper for making values thread-safe for access using a queue-based readers-writer lock.
  • UserDefault: A property wrapper that uses UserDefaults for storage. Requires that the property's type is Optional and Codable.
