Put your finger on the apostrophe and hold it for a second or two.

Based on regular keyboards, the backtick should appear if you hold down the tilde ~.

Actually, the backtick should be on a key of its own, while the tilde would appear when you held down the backtick.

I feel this is a grave error on Apple's part.
