comment Homotopy uniqueness of some coends
I am pretty sure the proof is precisely as Hirschhorn states: it is a consequence of applying corollary 18.4.14 to the result in proposition 14.6.3. Here, it is very important to read carefully and understand 14.6.3.

comment Homotopy uniqueness of some coends
Dear @Lano, your interpretation of Hirschhorn's proof appears to be incorrect. Nowhere does he claim that $X\otimes_{\mathscr{C}} \widetilde{K} \to X\otimes_{\mathscr{C}} K$ is a weak equivalence. In fact, that statement is false in general.
