 Kant does not need to mount a separate argument for transcendental idealism in the Transcendental Analytic, because while that is aimed at showing that the use of certain concepts (the categories of pure understanding) and principles (the principles of pure understanding) are necessary conditions of any cognition of objects at all, indeed of self-consciousness (apperception) itself, but also yield knowledge only when applied to intuitions, pure intuitions in the case of pure mathematical cognition and empirical intuitions in the case of everything else (thus Kant’s famous statement “Without sensibility no object would be given to us, and without understanding none would be thought. Thoughts without content are empty, intuitions without concepts are blind”, A 51/B 75), since empirical intuitions have already been shown to yield appearances rather than things in themselves, it automatically follows that the categories and principles of pure understanding will also yield cognition only of appearances. Nevertheless, Kant reaffirms transcendental idealism during the course of the Transcendental Analytic.
