Integration

CocoaPods

PXDToolkit is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "PXDToolkit", '~> 0.4'

If you are using Swift 3.x use PXDToolkit version 0.3.1:

pod "PXDToolkit", '0.3.1'

If you are using Swift 2.3 use PXDToolkit version 0.2.1:

pod "PXDToolkit", '0.2.1'

Add this to your podfile (if it is not already there) to make the pod work with Swift 4, 3.1 (or Swift 2.3):

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['SWIFT_VERSION'] = '4.0' # or the Swift version you are using
    end
  end
end

Carthage

You can use Carthage to install PXDToolkit by adding it to your Cartfile:

github "pixeldock/PXDToolkit"

NSLocalizedString

If your *Localizable.strings* file contains this:

And this: Get localized string with dynamic parts

print(LocalizedString("TEMPERATURE", arguments:[21.8, "Paris"])) // "It is 21.8°C in Paris"
