Use if/else logic instead of a ternary operator in Swift. Don't do this.

IfElseTernary.swift

func _if<T>(_ test: Bool, action: () -> T) -> T? {
	if test {
		return action()
	} else {
		return nil
	}
}

extension Optional {
	func _else(action: () -> Wrapped) -> Wrapped {
		if let value = self {
			return value
		} else {
			return action()
		}
	}
	
	func _elseIf(_ test: Bool, action: () -> Wrapped) -> Wrapped? {
		if let value = self {
			return value
		} else if test {
			return action()
		} else {
			return nil
		}
	}
}



let something = true
let somethingElse = true
let value = _if(something) {
	"A"
}._elseIf(somethingElse) {
	"B"
}._else {
	"C"
}
