Is Xcodes 9 still compatible?
So am lost, got the b4i and hosted builder but not the £99 apple license. I did pick up a cheap mac on high sierra to avoid the apple fee for now, but xcode 10 isn't compatible will xcode 9 work still? (its so slow dont think ill keep it long, no chance of the simulator running i dont think, no ssd and dont want to invest, rather just sell on and put it towards the apple license and test on the real devices i already bought )

EDIT: B4i V.6.00
