A collection of modules and the default platform availability for symbols in that module.

Discussion

Default availability is used as a fallback value for symbols without explicit availability information.

This information can be authored in the bundle’s Info.plist file, as a dictionary of module names to arrays of platform “name” and “version” pairs, or in the case where the platform in unconditionally unavailable, “name” and “unavailable” pairs:

<key>CDAppleDefaultAvailability</key>
<dict>
    <key>Module Name</key>
    <array>
        <dict>
            <key>name</key>
            <string>Platform Name</string>
            <key>version</key>
            <string>Version Number</string>
        </dict>
        <dict>
            <key>name</key>
            <string>Platform Name</string>
        </dict>
        <dict>
            <key>name</key>
            <string>Other Platform Name</string>
            <key>unavailable</key>
            <true/>
        </dict>
