Now it works!!! Thank you so much for your help!! By the way, you marked your own reply as SOLVED, this means your issue is solved. Have you find the solution? Now I can say "Yes" :)

I can share you the project and if it then doesn´t works, I will give up: https://www.icloud.com/iclouddrive/0RTt7FsW3rgq2LZLZeo7kCddA#TodoList

I did all what you said and I wroted the Project completley in English. It doesn´t works! What could I make wrong?

Yes, but where can I found the PROJECT./Info, or is it the file info.plist?

What is it? Please clarify what you have done. I changed the Language to German, but there stands still "Delete".

I have done it, but it doesn't works. :(

@OOPer: That I marked my own question to "Resolved" was a provided, but I don't know how can I undo this. How can I change the language settings in Xcode?

I mean this, if you swipe right, then stands there "Delete". How can I change this?
