Well, it's hard for me to justify paying Apple to get its operating system to trust Tiled. No other operating system requires such a fee. Maybe it would be worth it if I was selling software on the App Store, but Tiled is free. If I would charge for it on the App Store I would be misleading users into thinking they need to pay for it, and Apple would screw me over further by taking a whopping 30% cut.
If enough of my supporters care about this I could consider paying the $100/year fee. Until then, since Tiled is free software, you should be able to compile it yourself by following the linked instructions.
