The fig tree reference in Matthew 24 isn't a prophecy. It's an illustration, pointing to the stuff he just said.
32 “Now learn this parable from the fig tree: When its branch has already become tender and puts forth leaves, you know that summer is near. 33 So you also, when you see all these things, know that it[d] is near—at the doors! 34 Assuredly, I say to you, this generation will by no means pass away till all these things take place. 35 Heaven and earth will pass away, but My words will by no means pass away.
He's using the fig tree example as an illustration to say, that when you see ALL THESE THINGS, then you know the season is near.
The ALL THESE THINGS isn't the fig tree. It's all the things he talked about before using that illustration.
The fig tree is an illustration, not a prophecy.
