Can we combine Future Continuous with Present Simple into grammatically correct sentence?

Question

While learning English grammar I noticed that we can combine Past Perfect Continuous, Past Perfect and Past Continuous tenses with following actions (also in past) described in Past Simple.
e.g.: “We were swimming when it started to rain”

Similarly we can combine Future Perfect Continuous and Future Perfect with Present Simple.
e.g.: "How long will John have been working at the company by the time he retires?"
Does this rule apply also to Future Continuous and we can create grammatically correct sentence with Future Continuous + Present Simple? If so, could you please give some example?

Answer 1

Yes, that's fine.
