Hey everyone, I have been attempting to crack this code for a few days now and I still have yet to break any ground. The code is:
XHYF EW COV CLS YZQZ GUI ZYPFVJI, MWUR SW CVLIJ'W TVEN GPRF YRYSSEGU SM BVJPXPUH EE MXMWCOZ HB WCWI RAPZXIM DJCI CPYF
I know that "XHYF" means "July" and that "EW" means "is." I don't know where to go from there. I have tried just simply putting letters in place, such as "I" where every letter "E" is and did that with every letter I could, but it never came out to make any sense. Please, someone help solve this. Thank you so much!

Not strictly enigma but it's crypto so lets take a stab at it. Hard to guess without knowing more about it, what the context is and so on. If it is a cryptogram you could try to use www.cryptogram.org/resource-area/solve-a-cipher/ to solve it but when I tried it now it's not that much help. For a start, if "ew" is "is" then you get "ii" as a word but maybe that is roman 2 and then "ii" would be ok.

gta5codehitter , lpaseen You can try to see if this is mono-alphabetic cipher substitution. Here's a way to attack this: If this is a mono-alphabetic substitution, look at the last word. If that is not a name, but a word, then it ends in LY (YF is LY, if the first word is July). You then look at the list of 4 letter words ending in LY. Here's a link that can help: www.thefreedictionary.com/words-that-end-in-ly#w4 - not many options. However, the problem arises at the cipher text BVJPXPUH. Remember, if this is mono-alphabetic, then X is J so you are looking at a 9 letter word, having J in the last 4th place, but also surrounded by P, where P is determined by whatever CPYF (the last word is). If for example CPYF would be UGLY, then P would be G and you'd be looking for 9 a letter word in English that has GJG in the middle.
I'm having trouble finding such a combination, but like I said, I don't have time to invest in this for the next 3 weeks. You could also try frequency-analysis on this text, the links posted by lpaseen offers some help with the number of occurrences and it's easy to find the letter distribution of the English language. Another good way to look at this would be CVLIJ'W, where 'W can be 'S or 'T. However, if it's 'S then posibilities are way larger, as CVLIJ can be a verb or a noun/name.
If this is not a mono-alphabetic substitution, then you can try to attack this as you would attack a Vigenere cipher (non mono-alphabetic).
