In terms of meaning, hope and wish are very close to each other. However, ‘hope’ suggests more probability. Use ‘hope’ when there is hope (a chance) for something to happen. Use ‘wish’ in situations, which are imagined, or hypothetical. There is no negative meaning attached to ‘wish’, and no positive meaning attached to ‘hope’. However, when we say: “I wish you were here” we are primarily expressing a wish, a desire. Whereas when we say: “I hope you will be here” we are expressing an expectation. It is possible to say: I wish I could grow wings and fly. However, it would make no sense to hope for those wings to grow , to say that: I hope I will grow wings and fly.

Wish = To desire/Used to regret, for e.g "Wish I had worked harder"/Used to express unhappiness, for e.g "I wish my boss would be less grumpy". Hope = To expect/To want Moreover 'Wish' has a pessimistic tone to it, that is you don't think the thing you are wishing for would actually happen. 'Hope', on the other hand has an optimistic tone, that is, You expect what you hope for to happen.
