Hi
Same issue with me, I just started the Udemy course;
on MacOS Mojave 10.14.3 (18D109);
go version go1.11.5 darwin/amd64
Slobodankas-MacBook-Air:cards svlaskovic$ go build *.go
# command-line-arguments
./main.go:7:7: cards.print undefined (type []string has no field or method print)
Thank you,
Slobodanka
Adding the details to fix the error [just for future reference]:
Returning the type `deck` to cards instead of `[]string` will fix this issue. `print` accepts only `deck`. Below is the snippet
cards := _[]string_{ "Ace of Diamonds", newCard(), newCard()}
cards := **deck**{ "Ace of Diamonds", newCard(), newCard()}
