The Swift originally shipped with CyanogenOS, which is not the same thing as CyanogenMod. CyanogenOS already featured Truecaller on the dialler to show names on incoming calls. I was confused too when the dialler disappeared from my launcher, but I use it very rarely and essentially to receive calls so not a big deal for me. I understand OP's concerns though.
