Switch

Implementation

enum Animal {
	case dog
	case cat
	case wolf
}

let animal: Animal = .wolf
switch animal {
	case ...
	default: 
}

switch caseVar {
	case .caseOne: print("1")
	case .caseTwo: ()
	case .caseThree: break
}

SwiftUI ViewBuilder
break does not work with ViewBuilder

switch caseVar {
	case .caseOne: print("1")
	case .caseTwo: EmptyView()
}

The Swift If-Case-Let syntax is a convenient shortcut to avoid a full switch statement when you only want to match a single case.

Pattern Matching
You can do switch statement on enums as well as do specific case if needed.

// event: Enum type
if case .caseOne(let msg) = event {
	self?.log(error.description, level: .error)
	self?.playerError = error
}

Nesting cases with if let Result & enum switch type

// urlResult: Result type & urlType: enum
if case let .success(urlType) = urlResult,
	case let .parsed(urlParsed) = urlType {
}
