Not working in UC Browser in Iphone

[kambadprashant]

I am using this in one of my projects and it's throwing the following error:

t is not a function. (In 't(this,a,0)', 't' is "0")

Then, I have also checked from the provided demo page at http://bitwiseshiftleft.github.io/sjcl/demo/ and it's not working either.
(Not even able to generate salt using provided random button)

Device: iPhone XR (Ios 13) (v13.3.1)
Browser: UC Mobile (v11.3.5.1203)
