Simplify the introduction of XcodePreviews By SwiftUI

AutoPreviewable

Summary

Make class inheriting UIView correspond to XcodePreviews.The source code is automatically generated by Sourcery.
This was conceived to introduce StoryboardPreviewsBySwiftUI efficiently.

Usage

Please copy the following files to work in your environment.
You can automatically generate code by executing sourcery_previews.sh.

File	description
./Sourcery/sourcery_previews.sh	Execution script file
./Sourcery/sourcery.yml	Execution configuration file
./Sourcery/templates/AutoPreviewable.stencil	Sourcery template file
./setup.sh	Required software download script file

If you want to create a preview process, make the class compliant with AutoPreviewable.
The class must be final class.
Note that at this time, auto-generation is only supported for UIView.

protocol AutoPreviewable {}

final class AkkeyView: UIView, AutoPreviewable {
    // do something
}

There is another way to generate using annotations.

// sourcery: AutoPreviewable, xibLess
final class AkkeyView: UIView {
    // do something
}

By default, processing is performed assuming that there is an XIB file with the same name as the class name.
If the XIB file does not exist, specify as follows.

// sourcery: xibLess
final class AkkeyView: UIView, AutoPreviewable {
    // do something
}

To specify the height for previewing, write as follows.

// sourcery: customHeight=100
final class AkkeyView: UIView, AutoPreviewable {
    // do something
}
