It's hard to learn for native English speakers too. Maybe the hardest part is the fact that it's practically a requirement to learn both Standard Arabic and a dialect in order for it to be really useful. Two languages are harder than one  

Most dialects and derivative languages Have a lot of standard Arabic at their cores. I only speak Egyptian (which is a lot of slang) and closest to modern standard Arabic.My grandfather on one side speaks Libyan closer to standard Arabic. My grandparents on the other side speak Maltese (Maltese Arabic) which is a butchering of many languages including i think ...Italian Sicilian Spanish and Arabic. One side speak no English and we have always managed to converse. I taught my daughter (3 at the time) some Egyptian phrases before we visited friends in Taba and a few months after when my Libyan family came to visit in the UK she heard them speaking and chimed in with some Egyptian they were very emotional.
