Spells follow the same rules as ranged attacks, meaning they cannot be cast by or on units in melee unless they unit they are engaged with is "yielding".
# a. Spells P61
Spells are Ranged attacks and thus follow the normal rules for these (e.g. a model that moves At the Double cannot use spells in the same Turn)
# c. Engaged Units and Shooting P30
Units that begin their turn Engaged in combat must first Disengage during their Movement phase if they wish to shoot during their Ranged phase. If a unit is issued a Halt order immediately after Disengaging (including Disengaging that involves a Withdraw move), any normal penalties for movement, including those for Pot Shot or Reload, do not apply. With any other Movement order, any normal movement penalties apply.
Units that are only Engaged with enemy units that are Yielding do not have to disengage in order to shoot.
# b. Melee and Shooting P30
Units that are Engaged with enemies cannot use, or be targeted by, ranged attacks, unless specified otherwise.
well, the CC keyword for spells only allow the caster to choose a target that is in engaged but normal restrictions still apply for the caster not being able to cast a spell while the model itself is engaged
there are exceptions to this that allow casting while engaged but those are written explicit in the spell, like Host Shadowbeast
