Hi, I have a question, for my app, I used cloud kit for save a database. My database is public and the data is fletched on simulators, there works nice. But in real devices, after distributing, my app doesn't fletch the database, whereas this is public, why ?

Hello everyone, I have a problem. For using my app, many files must be reading ( 3 json files ) and at the end of the app theses files are updated. When I read my files, the directory changes any reboots. So, I decided use url from my Desktop, but when I simulate app on my phone, the app crashes because the Desktop isn't on my phone, and on the phone of the future user. So my question is is it posible to have the same directory any reboots ? And if is not, how I can manage my file for avoid this problem ? Thanks everyone
