Build iOS app

[shekohex]

Currently, we had issues to build our app into iOS targets, see #1 for more info.

So here is what I tried and it worked for now

0. Start Clean :)

   $ git clone https://github.com/sunshine-protocol/sunshine-identity-ui.git

1. Clone sysinfo locally

   $ git clone https://github.com/GuillaumeGomez/sysinfo.git

2. Edit sysinfo version (downgrade)

   [package]
   name = "sysinfo"
   -version = "0.14.14"
   +version = "0.13.14"

3. Patch our Cargo.toml files

Path: ./Cargo.toml

[patch.crates-io]
netstat2 = { git = "https://github.com/shekohex/netstat2-rs/", branch = "ios-support" }
sysinfo = { path = "../sysinfo" } # local sysinfo for testing

Path: ./native/identity-client/Cargo.toml

[dependencies]
# we don't use it in code directly..
ed25519-dalek = "=1.0.0-pre.3" # prevent update of ed25519-dalek

and Run cargo update after that (IMPORTANT).

4. Build The Project using cargo make

$ cargo make ios-release --profile release

that would take a while, get you a cup of coffee or watch a Netflix Movie ;)

okay, after that, Run

$ cargo make post-ios --profile release

5. Build the flutter App This a sanity check step, to make sure it builds as an iOS app and links everything together.

   $ flutter build -v ios --simulator

6. Run it start an iOS simulator open -a simulator and

   $ flutter run

That's it, hope it works for you too.

I get the following error on step 5

Encountered error while building for simulator.

Fixed it, and pushed a commit for that 1e82521b8bb415a06a5d88e82255f4e9c3f32bcd

It worked 🎉 Let's keep this open until the instructions on the README work (after substrate releases rc5)

I'm going to close this in favor of #7 which is a near duplicate, but it has the full instructions.
