My datastore script won't work?

I have API services enabled aswell

This is the script

local ds = game:GetService("DataStoreService"):GetDataStore("UserData")

game.Players.PlayerAdded:Connect(function(plr)
	local leaderstats = Instance.new("Folder", plr)
	leaderstats.Name = "leaderstats"
	
	local Swing = Instance.new("IntValue", leaderstats)
	Swing.Name = "Swing"
	
	local Coins = Instance.new("IntValue", leaderstats)
	Coins.Name = "Coins"
	
	local Rebirths = Instance.new("IntValue", leaderstats)
	Rebirths.Name = "Rebirths"
	
	local key = "plr-".. plr.userId
	local SavedData = ds:GetAsync(key)
	
	if SavedData then
		Swing.Value = SavedData[1]
		Rebirths.Value = SavedData[2]
		Coins.Value = SavedData[3]
	else
		local DataToSave = {Swing.Value, Rebirths.Value, Coins.Value}
		ds:SetAsync(key, DataToSave)
	end
end)

game.Players.PlayerRemoving:Connect(function(plr)
	local key = "plr-".. plr.userId
	local DataToSave = {plr.leaderstats.Swing.Value, plr.leaderstats.Rebirths.Value, plr.leaderstats.Coins.Value}
	ds:SetAsync(key, DataToSave)
end)
