The Swift Programming Language (Swift 4.2)
Swift Programming Series
This book can be downloaded and read in Apple Books on your Mac or iOS device.
Swift is a programming language for creating iOS, macOS, watchOS, and tvOS apps. Swift builds on the best of C and Objective-C, without the constraints of C compatibility. Swift adopts safe programming patterns and adds modern features to make programming easier, more flexible, and more fun. Swift’s clean slate, backed by the mature and much-loved Cocoa and Cocoa Touch frameworks, is an opportunity to reimagine how software development works.
This book provides:
- A tour of the language.
- A detailed guide delving into each language feature.
- A formal reference for the language.
What's New in Version 4.2
- Updated for Swift 4.2. - Added information about accessing all of an enumeration’s cases to the Iterating over Enumeration Cases section. - Added information about #error and #warning to the Compile-Time Diagnostic Statement section. - Added information about inlining to the Declaration Attributes section under the inlinable and usableFromInline attributes. - Added information about members that are looked up by name at runtime to the Declaration Attributes section under the dynamicMemberLookup attribute. - Added information about the requires_stored_property_inits and warn_unqualified_access attributes to the Declaration Attributes section. - Added information about how to conditionally compile code depending on the Swift compiler version being used to the Conditional Compilation Block section. - Added information about #dsohandle to the Literal Expression section.
After reading just the first few pages, I was hooked to the simple language of Swift and wanted to read each page after the next!
A Great Break from Objective-C
This specification marks a new foundation in iOS/Mac development, where the shackles of distractingly bad language design (merging two wholly-separate languages) and aggressively unclear syntax have been discarded. There’s a lot of hope I hold out for this language, although I would like to see some love for features that other functional hybrids have (such as Mixins from Ruby or Traits from Scala) in future revisions. It is exciting, however, to see the first nail in the coffin for Objective-C.
Great intro to the new language!
