Android XML to iOS Xib converter

This project converts Android layout files and resources into iOS layout files and resources.

It is composed of a few parts:

Plugin

The Gradle plugin does the actual conversion work. It adds a task in the ios group called xmlToXib. Running this task will convert the resources of the Android project into iOS assets and move them into the given destination. It is configured as follows:

plugins {
    id("com.lightningkite.androidlayouttranslator")
    //...
}
//...

val androidRuntimeVersion: String by extra
dependencies {
    //...
    implementation("com.lightningkite.androidlayouttranslator:android-runtime:${androidRuntimeVersion}")
    equivalents("com.lightningkite.androidlayouttranslator:android-runtime:$androidRuntimeVersion:equivalents")
}

androidLayoutConverter {
    iosProjectName = "My Project"
    iosModuleName = "MyProject"
    iosFolder = rootDir.resolve("ios")
    
    webProjectName = "MyProject"
    webFolder = rootDir.resolve("web")
}

You can read more about equivalents here.

This also generates Binding files like Android does

Android Safe Insets

A small project that makes a convenient way to handle safe insets in Android that translates effectively to iOS.

Setup:

Initialize ViewPump with our inflation interceptor as follows:

import com.lightningkite.safeinsets.SafeInsetsInterceptor

// somewhere before startup
ViewPump.init(SafeInsetsInterceptor)

Then use the interceptor in your activity:

class MainActivity : Activity {
    //...
    private var appCompatDelegate: AppCompatDelegate? = null
    override fun getDelegate(): AppCompatDelegate {
        if (appCompatDelegate == null) {
            appCompatDelegate = ViewPumpAppCompatDelegate(
                super.getDelegate(),
                this
            )
        }
        return appCompatDelegate!!
    }
}

On views that are supposed to have padding equal to the region taken by the status bar / button bar, add the following attribute:

app:safeInsets="top|horizontal"

And that's it!

XmlToXibRuntime

The iOS runtime for the translator. Fairly lightweight, it contains the following:

• CALayer tools, allowing layers to autosize and respond to UIControl states as they need. CALayer is used as the equivalent of a Drawable.
• A compoundDrawable extension, allowing you to reach a compound drawable.
• A set of labeled toggles, used to emulate Android's ChecKBox and RadioButton, based on M13Checkbox, a Cocoapod
• A set of custom views extending the ability to customize font usage.
• A XibView class that inflates a .xib of the same name, used to create Binding classes in iOS.
