Swift 5.0 achieves ABI stability on Apple platforms, allowing apps to use the OS-provided Swift runtime instead of bundling it, which reduces download sizes and enables better performance through deeper integration.
Swift 5 achieves ABI stability on Apple platforms, ensuring binary compatibility for apps and libraries across future Swift versions without needing to embed the Swift runtime in app bundles.
Sourcekitd powers essential editor features like code completion and refactoring in Xcode and SourceKit-LSP, handling both syntactic and semantic requests for Swift files.
Swift 5 turns on runtime checks for exclusive access to memory by default in release builds.
The article explores dictionary-related APIs in Swift across Unix, macOS, and iOS, highlighting their role in features like spell check and semantic analysis.
The article clarifies the distinction between bundles and packages on Apple platforms, often confused due to overlapping use cases.
The article introduces CharacterSet, a Foundation type in Swift for manipulating Unicode scalar values, distinct from Set<Character> despite its name, as it conforms to the SetAlgebra protocol rather than storing Character values directly.
Internationalisation (i18n) means building your app so it can support many regions and languages. Localisation (l10n) means actually translating and adapting it for a specific market.
I absolutely hate chatbots! So much that I added a rule to Quiet to hide/block chatbots from websites.
On Apple platforms, the FileManager class in the Foundation framework provides a robust abstraction for file system operations like creating, reading, moving, copying, and deleting files and directories, using paths or file URLs.
The article introduces DateComponents, a versatile Foundation type in Swift for representing either a specific calendar date or a duration of time, emphasising its use over hardcoded time intervals like 60 * 60 * 24 for a day.
The swift run command now includes a --repl option. This lets you start the Swift REPL and import library targets from a package.
Swift provides runtime type inspection through the Mirror API. This allows developers to examine arbitrary values and traverse object graphs without prior knowledge of types at compile time.
Swift 5.0 aims to achieve ABI stability to enable a stable runtime for operating systems, with module stability as a key focus that may land in this release or a later 5.x update.
Swift 4.2 is a major update that enhances compile times, debugging, the standard library, and moves closer to binary compatibility, while maintaining source compatibility with Swift 4 and 4.1 but marking the last release to support Swift 3 compatibility.
The Core Motion framework in Swift simplifies access to iOS and watchOS device sensors, enabling innovative user interactions beyond touch by leveraging a dedicated motion coprocessor for efficient accelerometer, gyroscope, and magnetometer data processing.
The Core Motion framework’s CMMotionActivityManager on iOS and watchOS uses a device’s motion coprocessor to process sensor data from accelerometers, gyroscopes, and magnetometers, determining user activities like walking, running, cycling, automotive travel, or being stationary with varying confidence levels.
NSDataDetector finds dates, links, phone numbers, addresses, and transit details in natural language text. It is a subclass of NSRegularExpression.
Asset catalogs in Xcode let you store not just images but also data files like JSON. This helps apps load faster on first launch by avoiding network calls.
Steve Jobs once said, “You have to pick carefully. I’m actually as proud of the things we haven’t done as the things I have done. Innovation is saying ‘no’ to 1,000 things.”
Apple’s Natural Language framework (iOS 12+) finally lets developers use the same powerful language-detection technology that powers Siri and system features.
Automatic Strong Passwords (iOS 12 / macOS Mojave) let Safari and your app generate truly random, high-entropy passwords that actually satisfy the site’s rules, no more “password too weak” after AutoFill.
The Swift community continues to expand, with developers increasingly relying on ecosystem projects to streamline app development for specific tasks. To foster better interaction, Swift Forums has introduced a new top-level category called Related Projects.
Swift.org has expanded its continuous integration testing system to include community-hosted nodes for additional platforms.
Swift 4.1 reimplements implicitly unwrapped optionals (IUOs) so they act as regular optionals with a flag that allows automatic unwrapping when needed, rather than as a distinct type.
