I want to check if a given string matches a file pattern. Does Swift have builtin support for filename globbing? Or is there any 3rd party packages for this?

I use fnmatch for this. It’s a C API but quite nice to call from Swift:

let txtMatches = fnmatch("*.txt", "hello.txt", 0) == 0
let jpgMatches = fnmatch("*.txt", "hello.jpg", 0) == 0
print(txtMatches, jpgMatches)
// prints: true false

See the fnmatch man page for more details.
