ExSwift

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 }
