About FwiCore

:warning: This readme describes FwiCore 1.x.x version that requires Swift 3.0.0.

The initial purpose of FwiCore is to reuse the code that had been written over and over again from one project to another. However, after a period of time, it becomes bigger and bigger and the original purpose was no longer valid. And today, the FwiCore's purpose is trying to become a single library to resolve most of daily tasks.

Installation with Swift Package Manager

.Package(url: "https://github.com/phuc0302/swift-core.git", majorVersion: 1),

Features

  • [x] extension: a set of extra functions to add to Apple Standard Frameworks.
  • [x] codec: a wrapper base64 encode/decode and hex encode/decode.
  • [x] i18n: custom localization implementation to support languages ISO3.
  • [x] json: inspire by JSONModel, but written in pure swift.
  • [x] manager > network: lightweight network implementation base on URLSession. The implementation only supports data task and download task.
  • [x] manager > persistent: lightweight core data implementation base on CoreData.framework. The implementation has buildin lightweight migration schema and simple CRUD.
  • [x] manager > reachability: Apple ObjC Reachability implemented in pure swift.
  • [x] operation: basic concerrency operation implementation.
  • [x] view model: simplify the implementation for both UICollectionView and UITableView that require to interact with core data.

The unique feature of this library is the buildin network layer and the operation. Both share the same OperationQueue and the number of threads can be adjusted. Thus, no matter how many background tasks or HTTP requests there are, all will be handled by single queue. This approach is best suit for any application which focus on low memory and best performance.

Requirements

  • Swift 3
  • iOS 8.0+

The image's name must follow these pattern, otherwise the function is not working correctly. However, the button's state will not be effected if the image is not available.

codec

Only available for Data & String

i18n

In order to use FwiLocalization, the precondition is:

  1. The folder's name that contains the localized string must be either ISO2 or ISO3: ex. en.lproj or eng.lproj.
  2. The file's name must be Localizable and the file's extension must be strings.
  3. The file must be added to project.
let localize = FwiLocalization.instance
localize.locale = "eng"

let text = localize.localized(forString: "Hello world.")

json

inspire by JSONModel, this parser will have similar features like: keyMapper, ignoreProperties, optionalProperties and so on. However, this implementation using protocol approach instead of abstract class, thus, it is more flexible. There is only one downside of the implementation is that it is required the model to be inherit from NSObject because this is heavily depends on KVO feature from ObjC and the primities value except String cannot be optional.

  • Auto map
class TestJSON: NSObject {
    var a: Int = 0
    var b: String?
}

let d: [String : Any] = ["a":1, "b":"Hello world"]
let (model, err) = TestJSON.map(dictionary: d)
  • Key mapper
class TestJSON: NSObject, FwiJSONModel {
    var a: Int = 0
    var b: String?
    
    var keyMapper: [String:String]? {
        return [
            "value1":"a",
            "value2":"b"
        ]
    }
}

let d: [String : Any] = ["value1":1, "value2":"Hello world"]
let (model, err) = TestJSON.map(dictionary: d)

FwiJSONSerialization

/// Convert model to dictionary.
func toDictionary() -> [String : Any]
/// Convert model to JSON as data.
func toJSONData() -> Data?
/// Convert model to JSON as string.
func toJSONString() -> String?

FwiJSONConvert

Class using for convert, because FwiJSONSerialization is dynamic protocol, using this for generic object.

/// Build a list from a list of models.
static func convert(array:) -> [Any]

FwiJSONDeserialization

/// Build a list of models from data.
static func map(arrayData:) -> ([Model]?, Error?)
/// Create model's instance and map dictionary to that instance from data.
static func map(dictionaryData:) -> (Model?, Error?)


/// Build a list of models.
static func map(array:) -> ([Model]?, Error?)
/// Create model's instance and map dictionary to that instance.
static func map(dictionary:) -> (Model?, Error?)

e.g.
class TestJSON: NSObject, FwiJSONModel {
    var a: Int = 0
    var b: String?
}

let (list, err) = TestJSON.map(arrayData: data)
let (model, err) = TestJSON.map(dictionaryData: data)

let (list, err) = TestJSON.map(array: array)
let (model, err) = TestJSON.map(dictionary: dictionary)

FwiJSONMap

/// Build a list of models.
class func map(array:) -> ([T]?, NSError?)
/// Create model's instance and map dictionary to that instance.
class func map(dictionary:) -> (T?, NSError?)
