A brief review of the harmonic superspace approach to the construction of $\mathcal{N}=2$ supersymmetric higher spin theories is given.
We define off-shell analytic harmonic gauge potentials of $\mathcal{N}=2$ supersymmetric higher-spin multiplets and of $\mathcal{N}=2$ superconformal higher-spin multiplets
for an arbitrary integer highest spin. The component contents of these $\mathcal{N}=2$ higher-spin supermultiplets are explicitly presented.
We also construct their cubic couplings to the hypermultiplet.
This short report summarizes the basic results of the series of published papers [1-3]
as well as announces those of the forthcoming article [4].
