1 and 3 are fine and are interchangeable. If you change 2 to, "I enjoyed spending time with you," it would also mean the same thing.

The second one is gramaticaly incorrect because you used 2 difirent tenses (past and present tense) The first and last sentance are perfectly fine but the last one is more formal then the others I [enjoyed] the time [spending] with you Past tense: "enjoyed" (Tip: a word ending in "ed" offten means it is in the past tense) Present tense: "spending" You have to stick with one tense thought a sentance which I'm sure you know 😂 To correct it, it could be either: "I [enjoyed] the time i spent with you" (Past tense) Or "I enjoy [spending] time with you" (Present tense) I hope this made sense to you and helped good luck on learning English you got this 🤗🤗

The first and last are correct!
