Oh no.
Alert from Xcode: Unsupported Swift Version The targets “SwiftDownTests” and “SwiftDown” contains source code developed with Swift 3.x. This version of Xcode does not support building or migrating Swift 3.x targets. Use Xcode 10.1 to migrate the code to Swift 4.

Swift property observers work on most variable declarations. This only helps if you want to watch variables and you're open to recompiling.

Property wrappers work on any variable that isn't top-level code.

In neither case does the "property" need to be a property of a class, struct, or enum.
Swift code demonstrating the use of the "willSet" property observer and the definition of an "Incrementing" property wrapper. The code sample is not a complete program, but the contents of the image are listed completely as follows: ``` var counter: Int = 0 { willSet { assert ( newValue >= counter ) } } @propertyWrapper struct Incrementing<V> where V: Comparable { var wrappedValue: V { willSet { assert ( newValue >= wrappedValue ) } } } func t() { @Incrementing var anotherCounter: Int = 0 ```

Book cover with a dinosaur with a distant stare dinosaur. The title is "all my friends are managers" with the word "managers" clearly being a replacement for a different original word.
