Various issues with getting examples to run

[David Lysenko]

So, while trying to get any example to work, I've met the following issues:

1. Already reported in one of the other issues, but the dioxus dependency references an invalid relative path.
2. ios_demo seems to be referencing invalid API. Seems to me like it's been developed during early stages of development and is not compatible with the version 1.0. I get a ton of different compile time errors while trying to compile:

Some errors have detailed explanations: E0412, E0425.

error: could not compile `dioxus-ios-demo` due to 9 previous errors

3. Other projects I tried seems to have similar issues when I try to run them on mobile (like the dog-app exits with a compile error in one of the dependencies after I ran cargo mobile init on it and fixed the cargo.toml file.)

It would be much appreciated if you guys tried to run all these examples yourselves and fixed the issues.

Also, whenever I try to fetch with the mobile feature, it tells me that the feature doesn't exist:

error: failed to select a version for `dioxus`.
    ... required by package `dioxus v0.1.0 (/Users/dlossenko/projects/dioxus)`
versions that meet the requirements `^0.1.6` are: 0.1.6

the package `dioxus` depends on `dioxus`, with features: `mobile` but `dioxus` does not have these features.


failed to select a version for `dioxus` which could resolve this conflict
