Codable - get source code for automatically generated init(from:) and encode(to:) methods

What is this Xcode shortcut you refer to?

The code snippet that generates these?

Swift:

init(<#parameters#>) {
		<#statements#>
	}

ObjC:

- (instancetype)init
	{
		self = [super init];
		if (self) {
			<#statements#>
		}
		return self;
	}

??

The Swift one could be significantly smarter and include the actual defined properties in the struct/class using SwiftSyntax.

I'm wondering if there's something else you're referring to that's "smarter" and more useful than the above. TIA.
