Explanation:

In Swift, the let keyword is used to define a constant value that cannot be changed once initialized. The == operator is used to check if two values are equal. The ! operator in Swift is the logical NOT operator which reverses a Boolean condition. SwiftUI uses a declarative syntax where you describe the user - interface in terms of what it should be, rather than how to build it step - by - step.

Answer:

1. B. let
2. B. ==
3. B. Reverses a Boolean condition
4. B. Declarative
