You + Stevia = 🦄

  • 💡 Write concise, readable layouts
  • 🏖 Reduce your maintenance time
  • 🎨 Compose your styles, CSS-like
  • 🔴 Plug Live reload and boost your iteration cycles

🖼 Visual Layout Api

layout(
    100,
    |-email-| ~ 80,
    8,
    |-password-forgot-| ~ 80,
    >=20,
    |login| ~ 80,
    0
)

Chainable Api

email.top(100).left(8).right(8).width(200).height(44)
alignHorizontally(password, forgot)
image.fillContainer()
button.centerInContainer().size(50%)
equalWidths(email, password)
image.width(>=80)

📐 Equation-Based Api

email.Top == 100
password.CenterY == forgot.CenterY
login.Top >= password.Bottom + 20
login.Width == 75 % Width
(image.Height == 100).priority = UILayoutPriority(rawValue: 999)

All Generate native NSLayoutConstraints 🎉

👨‍🔬Try it!

Stevia is part of freshOS iOS toolset. Try it in an example App ! Download Starter Project

💡 Reason

Because nothing holds more truth than pure code 🤓
Xibs and storyboards are heavy, hard to maintain, hard to merge.
They split the view concept into 2 separate files making debugging a nightmare
There must be a better way

How

By creating a tool that makes Auto layout code finally readable by a human being.
By coupling it with live code injection such as injectionForXcode we can design views in real time
View layout becomes fun, concise, maintainable and dare I say, beautiful ❤️

Login View Example

In the project folder, you can find an example of a typical login view laid out in both native and Stevia for you to understand and compare the two approaches.

As a spoiler alert, the number of characters goes from 2380 to 1239 ( ~ divided by 2)

Write Half the code that is actually 10X more expressive and maintainable !

🔴 Live Reload

Live reload enables you to develop your views live without relaunching the app everytime.

Stevia + InjectionForXcode = #WhoNeedsReactNative?? 🚀

Just Cmd+S and you can dev live in the simulator !
