_Hi Max,
thank you for your unbelievable nice codes! I'm new in this topic, actually studying architecture, I watched this tutorial https://www.youtube.com/watch?v=9R_G0EI-UoI and tried to use your code as it is shown in the video, but I don't get it work.
here is my code: please help me out. Thank you so much

Hi @LA35NE, as mentioned in Ryan's video, he uses package version 1.1.1; however the latest version is v2.0.1.
If you want to use the same version as Ryan does, please tell Xcode to use version 1.1.1, otherwise review the provided documentation to use the latest updates to the package.
hi Max,
thank you for your quick response. I installed the 1.1.1 Version like Ryan did in the video. In Ryans video after installing he changing some other things as well. would this changes been needed if I install the latest Version of FocusEntity?
More informations about the system: Xcode Version 12.0.1, using an iPhone X with ios14
thank you
I haven't tested this with iOS 14 since the GM, but everything should work very similarly, I think just initialising the object was the main change.
Otherwise there's a full example in this repo if you clone it, showing how to use the latest version of FocusEntity.
holy shit, it works, I don't know why but that's ok haha
thank you so much.
by the way I'm really impressed by the work you are doing!
stay healthy!

Cheers! Glad it's working for you now!!
