How to connect yandex metric to ios application?

Question

iOS

I do everything according to this instruction. But even the example fails to compile:

Install CocoaPods (http://cocoapods.org/) to manage project dependencies, if you haven't done it yet.
Clone repository: git clone https://github.com/yandexmobile/metrica-sample-ios
Go to cloned repository and install dependencies: pod install
Open project workspace MobileMetricaSample.xcworkspace.
Build and run MobileMetricaSample target.

The compiler always throws this error:

Googled this error. But nothing helps.

Let's go in order. Perhaps you missed some point.
1) You need to install the cocapods itself. It's a dependency manager that "simplifies" life. The installation manual is available at cocoapods.org/.
2) Then you need to pull off a turnip with an example project https://github.com/yandexmobile/metrica-sample-ios
3) go to the folder with the project and start the terminal from there. Or launch a terminal and drag that folder to the terminal and execute the cd command
4) run the pod intall command in the terminal. After a couple of seconds, the answer pod installed should glow
5) MANDATORY, run not the project file, but the workspace file MobileMetricaSample.xcworkspace
I suspect that you launched the project file, not the workspace file I
suspect that you have
