Can I say "will" instead of "can" here without changing the context?

I've never seen "take" is followed by "-ing" form! Could you explain this sentence for me?

Sure! Here, "take" is the main verb. The direct object of "take" is "me." "Swimming" is a gerund. The form of a gerund is "verb+ing." And here, it acts as part of the object and gives more information about where one would be "taken" to. So "You" is the subject, "take" is the main verb, "me" is the direct object, and "swimming" is the gerund that provides more information and context! It means to "lead," "accompany," or "escort" someone or something to a place or activity. Ex: She took me shopping = She took me to the shops. Ex: William will take me bowling this evening.

Doesn't "private" and "personal" are basically the same word? Or do they have some significant changes?

These two words are very similar in meaning, you are correct! However, there is a difference. Personal means belonging to or affecting a particular person rather than anyone else, whereas private means belonging to one specific person or group of people only. So you can think of it as private only applying to either a group/individual vs. personal only applying to an individual. However, they are used interchangeably quite often. Ex: This is my personal workspace. Ex: I don't like to share my private life with others.
