Xcode 4 Document Types and Exported UTIs

Question

I have an other problem with Xcode 4. I really like the new IDE but there are a few things I didn't get to work yet. One thing is to register Document Types with Xcode 4. I tried it with the old way through the plist file, but it didn't work. (Means I couldn't open a file with my app) But I don't now how to set it up with the interface of Xcode 4.

My latest try looks like this: (Copied the entry made from Xcode in the info.plist)

<key>UTExportedTypeDeclarations</key>
<array>
    <dict>
        <key>UTTypeConformsTo</key>
        <array>
            <string>public.plain-text</string>
        </array>
        <key>UTTypeDescription</key>
        <string>Configuration File</string>
        <key>UTTypeIdentifier</key>
        <string>com.myname.projec.iws</string>
    </dict>
</array>

and:

<key>CFBundleDocumentTypes</key>
<array>
    <dict>
        <key>CFBundleTypeIconFiles</key>
        <array>
            <string>AnIcon-320</string>
        </array>
        <key>CFBundleTypeName</key>
        <string>Config File</string>
        <key>LSItemContentTypes</key>
        <array>
            <string>com.myname.projec.iws</string>
        </array>
    </dict>
</array>

This does not work. The file in Mail doesn't have the option to open with my app.

Does anyone have a working example with Xcode 4 or a tutorial how to do it. I don't have any further Idea how to get it work.

I think the role and the file extension are missing.

If you want to specify a file extension, you need to add UTTypeTagSpecification:

    <key>UTExportedTypeDeclarations</key>

<array>

    <dict>
        <key>UTTypeConformsTo</key>
        <array>
            <string>public.text</string>
        </array>
        <key>UTTypeDescription</key>
        <string>my document type</string>
        <key>UTTypeIdentifier</key>
        <string>com.mycompany.myfiletypename</string>
        <key>UTTypeTagSpecification</key>
        <dict>
            <key>public.filename-extension</key>
            <array>
                <string>iws</string>
            </array>
        </dict>
    </dict>

For the role, you need to add CFBundleTypeRole:

<key>CFBundleDocumentTypes</key>
<array>
    <dict>
        <key>CFBundleTypeName</key>
        <string>My file</string>
        <key>CFBundleTypeIconFiles</key>
        <array>
            <string>document-320.png</string>
            <string>document-64.png</string>
        </array>
        <key>LSHandlerRank</key>
        <string>Alternate</string>
        <key>CFBundleTypeRole</key>
        <string>Viewer</string>
        <key>LSItemContentTypes</key>
        <array>
            <string>com.mycompany.myfiletypename</string>

        </array>
    </dict>
</array>
