ExSwift

CocoaPods Carthage compatible Build Status

Set of Swift extensions for standard types and classes.

Installation

Because of Xcode errors it's not possible to integrate this project with Cocoapods or as Embedded Framework. Read more at Dev Forum

Use submodule and copy source code

  1. Add ExSwift as a submodule
  2. Open the ExSwift project folder, and drag ExSwift sub folder with source code into the file navigator of your Xcode project. Make sure you select add to target
  3. Use it
components.takeFirst() { $0.completed }

SequenceOf

The following operations can be performed on sequences and are evaluated lazily. Each operation only takes the data it requires from the source sequence in order to return its result.

The Sequence protocol cannot be extended, hence the following are extensions to SequenceOf. They can be used as follows:

var source: Sequence = ...
var filteredSequence = SequenceOf(source).filter { ... }
