I'm looking for a list of methods that I can use on Array in Swift.
For example you can run isEmpty on an array, but I couldn't find a list of all methods.
For exmaple I couldn't find global functions like find in the formal documentation
When you cmd-click a built-in function or type Xcode displays a generated file with the entire contents of the module to which that function or type belongs. In this case, if you cmd-click a Swift type (like String) or function (like find), you can see the declarations for the entire Swift built-in library.

It's known, that when assigning an instance of structure to another instance, or passing it to a function, Swift essentially copies the instances by value. However I could not find anywhere if we actually have control over this process, like in C++ copy constructors. My question is whether Swift has analogue to C++ copy constructors and if not, are there anything in the language what helps to take control over passing-by-value process in Swift?
Copy constructors are implicit in Swift, and can't be user-customized.
They always copy all fields of a struct. For fields that are references to object, copying is defined as the increment of reference count (a retain).

The main aspect of CoffeeScript I'd like to see available also for Dart in form of a different, Dart-based language would be less verbosity, less brackets, less Java-style.
Does such solution exist ?
No.
If you don't want to have your field static you can omit the static keyword.
If you don't want to have your field final you can write var or a concrete type instead of the final keyword.
And if you don't want a loop you can omit for, while, forEach, ...

I understand these two methods are identical (one is defined in terms of the other) according to this previous question:
Scala Buffer: Size or Length?
But is there a reigning best practice or recommended convention? I can think of three options:
(1) Always use size
(2) Always use length
(3) Use size for all collections exception Array
I'm leaning towards (1) or (3). The rationale behind (3) is that these methods are inherited from Java. And in Java you'd be invoking collection.size() and array.length. The argument for (1) is that it builds on and simplifies (3). The argument for (2) I'm not really sure about.
They are the same. It makes no difference. Use whatever you want.

If you start typing in Xcode something like [selfSpace you see something like this:
What I want now is instead of filtering the results by method names I want to type e.g. NSString and get all methods back that return NSString (like description in this example) or all properties that I can set with NSString.

Is there any way that I can list all called methods like there are called one after the other? For example now I am doing same thing in way that I'm putting NSLog(#"MethodName"); i every that method.
I want to do that by automatic way in NSLog. Is it possible?
If you don't have too much methods you can use
NSLog(#"%#" , NSStringFromSelector(_cmd));
to log their names. This way you don't have to copy the signatures manually each time.
Create a property 'NSMutableArray *calledMethods;`
And in each of your method use
[self.calledMethods addObject:NSStringFromSelector(_cmd)];
And whenever you want to print it NSLog it.
I think you want:
printf("%s\n", __PRETTY_FUNCTION__ ) ;
Which produces (for example)
-[AppDelegate application:didFinishLaunchingWithOptions:]
Or, you can use dtrace. This answer should help: https://stackoverflow.com/a/3874726/210171.
Also check https://stackoverflow.com/a/4604249/210171 (same linked question). Seems there's an environment variable NSObjCMessageLoggingEnabled you can set...
