FIN messages and performances Read more. Read more. Operational status. The object is stored as a block of data placed on the heap , while the name or "handle" to that object is represented by a pointer.
Objects are passed between methods by copying the value of the pointer, allowing the same underlying data on the heap to be accessed by anyone with a copy.
In contrast, basic types like integers and floating-point values are represented directly; the handle contains the data, not a pointer to it, and that data is passed directly to methods by copying.
These styles of access are termed pass-by-reference in the case of objects, and pass-by-value for basic types.
Both concepts have their advantages and disadvantages. Objects are useful when the data is large, like the description of a window or the contents of a document.
In these cases, access to that data is provided by copying a or bit value, versus copying an entire data structure. However, smaller values like integers are the same size as pointers typically both are one word , so there is no advantage to passing a pointer, versus passing the value.
Also, pass-by-reference inherently requires a dereferencing operation, which can produce noticeable overhead in some operations, typically those used with these basic value types, like mathematics.
Similarly to C and in contrast to most other OO languages, [ citation needed ] Swift offers built-in support for objects using either pass-by-reference or pass-by-value semantics, the former using the class declaration and the latter using struct.
Structs in Swift have almost all the same features as classes: methods, implementing protocols and using the extension mechanisms.
For this reason, Apple terms all data generically as instances , versus objects or values. Structs do not support inheritance, however.
The programmer is free to choose which semantics are more appropriate for each data structure in the application. Larger structures like windows would be defined as classes, allowing them to be passed around as pointers.
Smaller structures, like a 2D point, can be defined as structs, which will be pass-by-value and allow direct access to their internal data with no dereference.
The performance improvement inherent to the pass-by-value concept is such that Swift uses these types for almost all common data types, including Int and Double , and types normally represented by objects, like String and Array.
To ensure that even the largest structs do not cause a performance penalty when they are handed off, Swift uses copy on write so that the objects are copied only if and when the program attempts to change a value in them.
This means that the various accessors have what is in effect a pointer to the same data storage. So while the data is physically stored as one instance in memory, at the level of the application, these values are separate and physical separation is enforced by copy on write only if needed.
A key feature of Objective-C is its support for categories , methods that can be added to extend classes at runtime. Categories allow extending classes in-place to add new functions with no need to subclass or even have access to the original source code.
An example might be to add spell checker support to the base NSString class, which means all instances of NSString in the application gain spell checking.
The system is also widely used as an organizational technique, allowing related code to be gathered into library-like extensions.
Swift continues to support this concept, although they are now termed extensions , and declared with the keyword extension. Unlike Objective-C, Swift can also add new properties accessors, types, and enums to extant instances [ citation needed ].
Another key feature of Objective-C is its use of protocols , known in most modern languages as interfaces.
Protocols promise that a particular class implements a set of methods, meaning that other objects in the system can call those methods on any object supporting that protocol.
This is often used in modern OO languages as a substitute for multiple inheritance , although the feature sets are not entirely similar.
A common example of a protocol in Cocoa is the NSCopying protocol, which defines one method, copyWithZone , that implements deep copying on objects.
In Objective-C, and most other languages implementing the protocol concept, it is up to the programmer to ensure that the required methods are implemented in each class.
Combined, these allow protocols to be written once and support a wide variety of instances. Also, the extension mechanism can be used to add protocol conformance to an object that does not list that protocol in its definition.
For example, a protocol might be declared called StringConvertible , which ensures that instances that conform to the protocol implement a toString method that returns a String.
In Swift, this can be declared with code like this:. In Swift, like many modern languages supporting interfaces, protocols can be used as types, which means variables and methods can be defined by protocol instead of their specific type:.
It does not matter what sort of instance someSortOfPrintableObject is, the compiler will ensure that it conforms to the protocol and thus this code is safe.
As Swift treats structs and classes as similar concepts, both extensions and protocols are extensively used in Swift's runtime to provide a rich API based on structs.
A concrete example of how all of these features interact can be seen in the concept of default protocol implementations :. This function defines a method that works on any instance conforming to Equatable , providing a not equals function.
Any instance, class or struct, automatically gains this implementation simply by conforming to Equatable. As many instances gain Equatable through their base implementations or other generic extensions, most basic objects in the runtime gain equals and not equals with no code.
This combination of protocols, defaults, protocol inheritance, and extensions allows many of the functions normally associated with classes and inheritance to be implemented on value types.
This concept is so widely used within Swift, that Apple has begun calling it a protocol-oriented programming language.
They suggest addressing many of the problem domains normally solved though classes and inheritance using protocols and structs instead. It also depends on Grand Central Dispatch.
To aid development of such programs, and the re-use of extant code, Xcode 6 and higher offers a semi-automated system that builds and maintains a bridging header to expose Objective-C code to Swift.
This takes the form of an additional header file that simply defines or imports all of the Objective-C symbols that are needed by the project's Swift code.
At that point, Swift can refer to the types, functions, and variables declared in those imports as though they were written in Swift.
Objective-C code can also use Swift code directly, by importing an automatically maintained header file with Objective-C declarations of the project's Swift symbols.
Not all symbols are available through this mechanism, however—use of Swift-specific features like generic types, non-object optional types, sophisticated enums, or even Unicode identifiers may render a symbol inaccessible from Objective-C.
Swift also has limited support for attributes , metadata that is read by the development environment, and is not necessarily part of the compiled code.
Like Objective-C, attributes use the syntax, but the currently available set is small. One example is the IBOutlet attribute, which marks a given value in the code as an outlet , available for use within Interface Builder IB.
An outlet is a device that binds the value of the on-screen display to an object in code. On non-Apple systems, Swift does not depend on an Objective-C runtime or other Apple system libraries; a set of Swift "Corelib" implementations replace them.
Apple used to require manual memory management in Objective-C, but introduced ARC in to allow for easier memory allocation and deallocation.
A references B, B references A. This causes them to become leaked into memory as they are never released. Swift provides the keywords weak and unowned to prevent strong reference cycles.
Typically a parent-child relationship would use a strong reference while a child-parent would use either weak reference, where parents and children can be unrelated, or unowned where a child always has a parent, but parent may not have a child.
Weak references must be optional variables, since they can change and become nil. A closure within a class can also create a strong reference cycle by capturing self references.
Self references to be treated as weak or unowned can be indicated using a capture list. A key element of the Swift system is its ability to be cleanly debugged and run within the development environment, using a read—eval—print loop REPL , giving it interactive properties more in common with the scripting abilities of Python than traditional system programming languages.
The REPL is further enhanced with the new concept playgrounds. These are interactive views running within the Xcode environment that respond to code or debugger changes on-the-fly.
If some code changes over time or with regard to some other ranged input value, the view can be used with the Timeline Assistant to demonstrate the output in an animated way.
In addition, Xcode has debugging features for Swift development including breakpoints, step through and step over statements, as well as UI element placement breakdowns for app developers.
Apple says that Swift is "an industrial-quality programming language that's as expressive and enjoyable as a scripting language".
Many of the features introduced with Swift have well-known performance and safety trade-offs. Apple has implemented optimizations that reduce this overhead.Die Society for Worldwide Interbank Financial Telecommunication, abgekürzt SWIFT, ist eine gegründete, in Belgien ansässige Organisation, die ein besonders sicheres Telekommunikationsnetz betreibt, welches insbesondere von mehr als Die Society for Worldwide Interbank Financial Telecommunication, abgekürzt SWIFT, ist eine gegründete, in Belgien ansässige Organisation, die ein.
