I have using a API Response that is not in JSON format but wanted to still decode it, what are the ways that can achieve this stage.

Trying to fetch JSON data from an external website for two ISBN numbers and the Curl from that site is shown below. When using the AF.request it works fine for one isbn but when trying the string in the curl request with isbn numbers separated by a common it returns no results. Instead of a comma I have also tried & and &20 and + and nothing seems to work. The website lets you plug in both ISBN numbers and will show you results and gives you the curl statement so I know the curl statement works. Any help is appreciated!

in app I have cert domain.com (that cert will expire soon), I need to change it to cert *.domain.com. I use Alomofire and old cert was in app as file. Are there any difficulties in replacing *.domain.com?
