The Mapzen iOS SDK can be included in any iOS app via Cocoapods. It includes everything you need to get started, and includes a sample app you can also give a spin.
We're going to assume you have the latest stable build of Cocoapods installed. If not, check out how to install it over at https://cocoapods.org/
You can try out the SDK using:
pod try Mapzen-ios-sdk
Adding to your app is as simple as adding the following to your app's podfile:
pod 'Mapzen-ios-sdk'
