In Swift, @objc is used to expose a method, property, or class to Objective-C, while @nonobjc is used to explicitly hide an entity from Objective-C.
The main difference between callAsFunction and @dynamicCallable is that the former is more static and type-safe, while the latter is more dynamic and flexible.
You can create as many xcconfig files as you want, and you can specify different build configuration files for debug and release builds, and for different platforms and architectures.
Set is a generic type that can store any type that conforms to the Hashable, OptionSet is a protocol that can be adopted by custom types that store a fixed-size sequence of bits.
Macros are a feature present in a number of languages that allow one to perform some kind of transformation on the program's input source code to produce a different program.
A data race is when two threads access the same mutable object without synchronization, while a race condition is when the order of events affects the correctness of the program.
If you don’t care about the order, you can use a Set or Dictionary to remove any duplicates, and then convert it back to an array.
The @dynamicMemberLookup attribute enable you to access properties of a type that are not declared at compile time, but resolved at runtime.
The attribute dynamicCallable allows you to mark a type as being directly callable, then you can use a simpler syntax to invoke methods on that type, instead of using dot notation.
A special method that allows you to call an instance of a type as if it were a function, useful for creating callable objects that encapsulate some logic or state.
