Xcode custom template

In this article we will create a template that creates a view and a viewModel files.
In the previous article http://trikalabs.com/xcode-templates/ we explore how to create a simple file template.

Now let’s add a folder under the “Templates” folder and let’s name it SwiftUIMVVM.xctemplate.

Inside this folder we will need the TemplateInfo,plist file and a subfolder with our file templates.

Let’s create the TemplateInfo,plist (We can copy an existing one and modify it).

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">

			<key>Values</key>
			<array>
				<string>MVVM Template</string>
			</array>
		</dict>
	</array>
</dict>
</plist>

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

</array>

</dict>

</plist>

We created a module name input variable and the name of the folder which contains the file templates.

Now let’s create the two file templates:

And let’s edit the ViewModel first:

import Combine

class ___FILEBASENAME___: ObservableObject {

    init() {
        
    }
}

import Combine

class ___FILEBASENAME___: ObservableObject {

init() {

}

And then the view

import SwiftUI

struct ___FILEBASENAME___: View {
    @ObservedObject private var viewModel: ___FILEBASENAME___Model
    
    init(viewModel: ___FILEBASENAME___Model) {
        self.viewModel = viewModel
    }
    
    var body: some View {
        EmptyView()
    }
}

import SwiftUI

struct ___FILEBASENAME___: View {

@ObservedObject private var viewModel: ___FILEBASENAME___Model

init(viewModel: ___FILEBASENAME___Model) {

self.viewModel = viewModel

}

var body: some View {

EmptyView()

}

Now when create a new file in Xcode we can see the new option:

we can name it:

And we can see the new files

If we look on the View file for example we see that everything is being created as expected:

import SwiftUI

struct FeatureAView: View {
    @ObservedObject private var viewModel: FeatureAViewModel
    
    init(viewModel: FeatureAViewModel) {
        self.viewModel = viewModel
    }
    
    var body: some View {
        EmptyView()
    }
}
