Quick Friday tip!
Highlight some code in Xcode, hold down Shift then type a quotation mark; or an opening parenthesis; or an opening curly brace; or an opening square bracket. This automatically wraps your highlighted code in the character you typed.

I’d add that if nil and empty have different meanings for your case, it’s clearer in intent to create a dedicated enum with clear semantic. Typical example: enum LoadingState<T> { case notLoaded case loaded(T) } var books: LoadingState<[Book]>

#SwiftTip: Avoiding Degenerate Optional Values Avoid designing your code with `Optional` collections and booleans. Otherwise, you will run into a degenerate case, where it is unclear what does "nothing" mean. Is it an empty array or `nil` array; is it `false` or `nil`?pic.twitter.com/DY1WPlIRne

SwiftUI is a great framework, but sometimes we need to reuse UIKit views that we had for years in iOS SDK. Fortunately, it is very effortless to do with help of UIViewRepresentable protocol. This week we will learn how to use UIKit views in SwiftUI.https://swiftwithmajid.com/2020/01/29/using-uikit-views-in-swiftui/ …

Introducing swift-doc: an (experimental) command-line utility for generating documentation for Swift projects. https://github.com/SwiftDocOrg/swift-doc … It's still early on, but I'm really excited about the infrastructure behind it, and how it can be used to develop Swift tooling.

Interesting use case,
@V8tr ! An alternative to a relatively slow Reflection could be a bitwise comparison. Something like that: https://github.com/nalexn/ViewInspector/blob/c430cda6e869ea92c9891c56a20eff5c6a3080de/Sources/ViewInspector/BaseTypes.swift#L126 …Hvala.

#SwiftTip : XCTAssertEqual for Non-Equatables Almost every unit test asserts values for equality. If the values conform to Equatable, we use XCTAssertEqual(). Otherwise, we compare field-by-field or changes the production code. DumpEqual() solves this with reflection
