iOS SDK error: framework Crash : Thread 1: "+[NSString visitorID]: unrecognized selector sent to class 0x1ef0739a8"

I use the ios framework -GitHub - PiwikPRO/piwik-pro-sdk-framework-ios version 1.1.4 - with xcode swift package manager.

When I want to send anything to the server - e.g.: PiwikTracker.sharedInstance()?.sendView(view: “Menu”) - I get this error message:
Thread 1: “+[NSString visitorID]: unrecognized selector sent to class 0x1ef0739a8”

What do I do wrong?

Mac os: 12.4
Chip: Apple M1 Max
Xcode Version: 13.4.1 (13F100)

Hi Ssafian, welcome to our Community!

The description you gave seems a bit vague, can you share with me a print screen of the implementation in your code and the whole output from debug console in a personal message so I can address it?
