Stack overflow | the world’s largest online community for developers. Perhaps a nice idiom for declaring constants for a class in swift is to just use a struct named myclassconstants like the following. struct myclassconstants{ static let teststr = "test" static let teststrlength = countelements(teststr) static let arrayoftests: [string] = ["foo", "bar", teststr] } in this way your constants will be scoped within a declared construct instead of floating around. Why did i get “ fatal error: unexpectedly found nil while unwrapping an optional value ”? in order to access an optional’s value (if it has one at all), you need to unwrap it. an optional value can be unwrapped safely or forcibly. if you force unwrap an optional, and it didn't have a value, your program will crash with the above message. xcode will show you the crash by highlighting a.
