Unable to add images to image button in Xcode

Question

I'm new for macOS app development I'm trying to add image button to my view and I wanna see image after the text, so I'm dragging & dropping image button to view controller and writing title and after that, in image section I choose my image.

But my issue is if I will choose the system images my project works perfectly but if I will import a file by clicking project name > add files to.. and importing png, jpg,jpeg file to my project and choosing this image Xcode gives me this error;

CodeSign build/Debug/test.app
    cd /Users/feora/Documents/apps/test
    export CODESIGN_ALLOCATE=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/codesign_allocate

/Users/feora/Documents/apps/test/build/Debug/test.app: resource fork, Finder information, or similar detritus not allowed

Something is wrong with this page but I can't find which one

That's because when you're add image file you're also adding some Finder metadata related to that image. If you've searched error you're getting at least a little bit, you'd have found answers like this .
