Can Data From a Samsung Smart Switch Backup Be Restored to an iPhone XS Max?

A month and a half ago, I purchased my first iPhone. I've been an Android user my entire life, and I've had the same 200GB microSD card for around ten years. Any time I changed to a new phone, I would simply pop in the same SD card. I knew going in that iPhones don't have expandable storage, but I've been hitting a brick wall trying to transfer my text messages and apparently so has everyone else. The folks at the Genius Bar, Best Buy, Samsung Telephone Support, Apple Online Support, AT&T support... 'Move to iOS' didn't work... I have what I think might be 'OTG' cables but when I connect the phones nothing happens. I caved and bought one of those paid phone switch programs: still didn't work. Finally I was able to get everything backed up to my Mac using SmartSwitch, but has anyone been able to move data from a SmartSwitch backup to an iPhone? Thanks!
