Consider this example
class Foo {
private let bar = "bar"
lazy var baz : String = {
return "baz \(bar)"
}()
}
Unfortunately this won't compile and give the following error
'Foo.Type' does not have a member named 'bar'
I really do not want to declare bar outside the class (globally). Is there no other way to keep this inside the class and why isn't bar accessible in the first place?
TL;DR: preface with self
Swift can be quite misleading with error messages, but in this case, the answer can be deduced from the message. It is looking for bar on type Foo.Type, whereas you are trying to reference an instance variable. Here is code that works:
class Foo {
private let bar = "bar"
lazy var baz : String = {
return "baz \(self.bar)"
}()
}
In lazy props you need to say self
lazy var baz : String = {
let bar = self.bar
return "baz \(bar)"
}()
