Is it possible to use “should have done” to state something which will happen in the future? What I’ve read in my grammar textbook is that this structure is used to state something which happened in the past, but I heard this structure in a conversation. Here is the sentence I heard during the conversation:
Well, check with me tomorrow morning. I should've found something by then. It might not be ideal.
Should have can be used both retrospectively to reflect on an action that one ought to have taken (and didn't) - or to express a view about a future outcome in the sense of it is likely that.
In your example should have (plus past participle) is used in this second sense.
