After running R CMD check SSLR_0.9.0.tar.gz there is a file SSLR.Rcheck/SSLR-Ex.R. Try running that
R -f SSLR.Rcheck/SSLR-Ex.R
my guess is that somewhere else in the examples you load a package that has a generic 'fit' that masks SSLR::fit in your package, so R is not able to find your method on the tidymoodels::fit generic.
tidymodels would seem to be a good candidate for this, with perhaps some of the search path management done by in SSLR-Ex.R meaning that the mask is not reported by tidymodels. Also running the SSLR-Ex.R script used during check means effectively
library(SSLR)
library(tidymodels)
(tidymodels::fit masks SSLR::fit) whereas running just the example gives
library(tidymodels)
library(SSLR)
(SSLR::fit masks tidymodels::fit).
Hmm, after taking the time to tidymodels I see
> fit
function (object, ...)
{
UseMethod("fit")
}
<bytecode: 0x7f857dacf9a0>
<environment: namespace:generics>
so apparently there is a generics package that defines 'fit'... if you're playing in the tidyverse then it seems like you should @importFrom generics fit and @export fit.

'fpalomares', it's not clear if you can reproduce this locally or not,
but make sure you can reproduce it locally. I could using:
R CMD check --as-cran SSLR_0.9.0.tar.gz
with R 3.6.3 on Ubuntu 18.04. In other words, this is neither a
problem with the CRAN incoming checks nor win-builder.
Yes, I agree, at a first glance, this looks odd because:

{
UseMethod("fit")
}
<environment: namespace:SSLR>
> methods("fit")
[1] fit,onlearn-method fit.model_sslr
see '?methods' for accessing help and source code
Neither
$ Rscript -e 'example("COREG", package = "SSLR")'
nor
> example("COREG", package = "SSLR")
in an interactive session produce the error.
For troubleshooting, I'd added a:
print(methods("fit"))
before
m <- COREG(max.iter = 2) %>% fit(class ~ ., data = train)
I'd also try rewriting that without %>%, e.g. something like
a <- COREG(max.iter = 2)
b <- fit(class ~ a, data = train)
to see if that makes a difference.
