Morphology

say + you + swear

The meaning is directly compositional: 'say' (state verbally) + 'you' (the addressee) + 'swear' (make a solemn promise) yields a request that the addressee verbally promise or affirm sincerity. This speech-act construction (verb of saying + clause expressing an oath) is cross-linguistically common, so a B1 learner who knows the constituents would readily infer the intended meaning.

Etymology

The phrase say you swear comes from the simple idea of asking someone to say the word swear, like when people put a hand on a book and promise to tell the truth. So it now means 'ask someone to make a serious promise' or 'check they are telling the truth'.
