Will it cause a address lost when run in other devices?

[Ibroad]

I used cocoapods to install a third-party library called CSV.swift to read .csv files in my app. And I used a local path to let the library read the file. When I add the .csv file to my project I check Copy items if needed. Does it make sure my app won’t crash because file address lost when run in other devices? If not, how can I fix the problem?

If your .csv file is included in your project, then you should read it from the Bundle, not from a local path. That absolute path won’t be available on other devices.

Could you explain it further? I know how to create a bundle and add files into it, but I don’t know how to read file from it making the file available when running on the other devices.
Thanks for your reply

You would do something like this:

if let csvFile = Bundle.main.path(forResource: "language" ofType: "csv") {
    let stream = InputStream(fileAtPath: csvFile)
    //do whatever else you gotta do
} else {
    //gracefully handle your error
}
