   The Swift Book is good for this:

   Definitely check out swift.org/ . A few pages that are good jumping points are:

   Yes, 100 Days of Swift (and, really, anything by Paul Hudson (@twostraws)) is really good and recommended all over the place.

   One more resource I'd add for a beginner, the book The Swift Programming Language: https://docs.swift.org/swift-book/documentation/the-swift-pr...

   There's a free book "The Swift Programming Language" that should answer most questions about the Swift language and its standard library. The web version is here: https://docs.swift.org/swift-book/index.html

   Sure. Hacking with Swift [0] is great, CS193P [1] is very good (previous years were UIKit, now it's SwiftUI). Ray Wenderlich [2] and Swift by Sundell [3] are also good resources. The OG was NSHipster [4], but they haven't published much recently (some articles may be a bit outdated). For SwiftUI specifically, Swift with Majid [5] is a godsend and has amazing content. Finally, for learning good Swift language practices, the Swift book [6] is very friendly.

   Edit: forgot https://www.objc.io, definitely one of the best

   I don't know if you tried reading The Swift Programming Language book ( https://docs.swift.org/swift-book/LanguageGuide/TheBasics.ht... ). It's a fairly quick read and has brief explanations with simple examples. You can skip some sections if you have prior programming experience, but if you're confused about Swift's function arguments, you may want to skim even the basics since a few things like control flow (e.g. the switch statement) are unique compared to C/C++/Java/C#.
