Why Doesn't Swift Package Manager Ask For A Filename?

Somehow, as of Xcode 14, that's how the default template is configured for Swift package files.

You can change the behaviour by adding a custom template.

• Create the directory ~/Library/Developer/Xcode/Templates/File Templates/Source/Better Swift.xctemplate/
• Create a standard ___FILEBASENAME___.swift in it
• Create IDETemplateMacros.plist in it with

<?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">
<dict>
    <key>SupportsSwiftPackage</key>
    <true/>
    <key>Kind</key>
    <string>Xcode.IDEFoundation.TextSubstitutionFileTemplateKind</string>
    <key>Description</key>
    <string>An empty Swift file.</string>

            <true/>
            <key>Name</key>
            <string>Name:</string>
            <key>Description</key>
            <string>The name of the file to create</string>
            <key>Type</key>
            <string>text</string>
            <key>NotPersisted</key>
            <true/>

</plist>
