Combine peach Jello and boiling water in a bowl and stir until Jello is dissolved.

Set aside to cool slightly.

In a saucepan, combine peach syrup and mini marshmallows.

Heat over low heat, stirring constantly, until marshmallows are melted.

Remove from heat and let cool slightly.

In a separate bowl, mix cream cheese and salt until smooth.

Add the marshmallow mixture to the cream cheese mixture and mix well.

Gently fold the yogurt into the Jello mixture.

Add cherries and peach slices into the Jello mixture and mix until combined.

Pour the salad mixture into a serving dish or individual cups.

Cover and chill in the refrigerator for at least 3 hours, or preferably overnight, to allow the salad to set completely.
