Swift version: 5.1
Swift’s booleans have a
toggle() method that flip them between true and false. That might sound simple, but the end result makes for much more natural Swift code:
var loggedIn = false loggedIn.toggle()
This is particularly useful in more complex data structures:
myVar.prop1.prop2.enabled.toggle() avoids the potential typing errors that could be caused using manual negation.
