The iPhone is not one that gets malware/spyware, or can be hacked if at all or even a slight bit from all that I know about them. I’ve owned quite a few apple products and can say with pretty good certainty that they don’t have virus or malware issues like devices that run open source apps and such. Not sure what you are concerned with about your phone. If you have given your iCloud info and/or personal info to someone, then yes, maybe some one got your stuff, but for someone to openly hack your phone is pretty near impossible as far as I know.
