chmod +x not working as expected, running another tool instead

Just wrote a simple commandline tool which works fine with swift but doesn't run as executable after chmod +x ... This is happening on my system so might be configuration related but not sure how to resolve. --- #### Create Script: vi test.swift #### Enter content: import Foundation print("Hello, World!") Running normally swift test.swift gives Hello, World! as expected but when I make it executable & run it then it's failing. #### Make Executable: chmod +x test.swift ./test.swift #### Output: Version: ImageMagick 7.1.0-52 Q16-HDRI aarch64 20549 https://imagemagick.org Copyright: (C) 1999 ImageMagick Studio LLC License: https://imagemagick.org/script/license.php Features: Cipher DPC HDRI Modules OpenMP(5.0) Delegates (built-in): bzlib fontconfig freetype gslib heic jng jp2 jpeg lcms lqr ltdl lzma openexr png ps raw tiff webp xml zlib Compiler: gcc (4.2) Usage: import [options ...] [ file ] Image Settings: -adjoin join images into a single multi-image file By default, 'file' is written in the MIFF image format.

Why is it running commandline tool imagemagick?
