Building iOS apps with Nix?

I got an iPhone and am wondering if anyone has found a way of making iOS apps with Nix, from NixOS of course.

I’m also interested in this.

I don’t exactly know what you mean.
You can write nix expressions to build packages that targets the iOS platform, but that would mean writing an iOS app with a language that is made to do that first (like swift).

Yeah but isn’t there something like a signing step?

I found this but I never used it myself, so I don’t know if this is what you are searching for

Didn’t realise there was something in Nixpkgs: Nixpkgs Reference Manual. It’s the same as what you linked.

I think it’s meant to be used on MacOS though unfortunately.

isn’t that a requirement imposed by apple? If so there is nothing nixos can do about it

It is, but the idea was that there’s likely a way of bypassing it. There’s NixThePlanet, but it runs MacOS in a VM (from inside Nix!), which I’d rather avoid since it’s quite heavy.
