Important

You need to set Allow Arbitrary Loads to YES on your project’s Info.plist file.

If you don’t want to use the option above and you are using SwiftLinkPreview for services of your knowledge, you can whitelist them on Info.plist file as well. You can read more about it here, here and here.

Tips

Not all websites will have their info brought, you can treat the info that your implementation gets as you like. But here are two tips about posting a preview:

  • If some info is missing, you can offer the user to enter it. Take for example the description.
  • If more than one image is fetched, you can offer the user the feature of picking one image.

Tests

Feel free to fork this repo and add URLs on SwiftLinkPreviewTests/URLs.swift to test URLs and help improving this lib. The more URLs the better the reliability.
