By addition of a soluble silver salt; typically $A g N O_{3} (a q)$ $AgNO_3(aq)$ .

Explanation:

$A g (N O_{3}) (a q) + X^{-} \to A g X (s) ⏐ ⏐ ↓ + N O_{3}^{-}$ $Ag(NO_3)(aq) + X^(-) rarr AgX(s) darr + NO_3^-$

$Silver chloride$ $"Silver chloride"$ forms a curdy, insoluble white precipitate. $Silver bromide$ $"Silver bromide"$ forms a curdy, insoluble cream-coloured precipitate, $Silver iodide$ $"Silver iodide"$ forms a fine yellow precipitate. On standing, the precipitate reduces to metallic silver.

All of the silver halides are quite insoluble, See here for more details.
