Hey, Congrats on the AC! A basic SWOT is to evaluate the strengths, weaknesses, opportunities and threats of whatever they are asking you to do it on.
For example, a SWOT for a brick and mortar retail business could be:
Strengths - established, local knowledge of business, USP of company
Weakness - brick and mortar so no online shopping offering for wider audience of potential customers
Opportunity - expand to online, could provide existing in-person customers a bonus or discount if recommending friends to shop online, potentially have reps for the business like body shop has with consultants
Threats - competition businesses, increased rates and overheads for brick and mortar store, economy issues
Hope this gives you a general idea and good luck!
