如何用plutil移除plist文件中的com.apple.developer.associated-domains键

构建阶段使用plutil操作plist文件（如Info.plist和Entitlements.plist）时，执行plutil -remove "key1"这类命令可正常移除各类键，但执行以下命令移除com.apple.developer.associated-domains键时：

plutil -remove "com.apple.developer.associated-domains"

返回错误：

No value to remove at key path com.apple.developer.associated-domains

但该键明确存在于目标Entitlements.plist文件中，文件内容如下：

<?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>aps-environment</key>
    <string>development</string>
    <key>com.apple.developer.associated-domains</key>
    <array>
        <string>applinks:mycompany.com</string>
        <string>applinks:mycompany.com*</string>
    </array>
</dict>
</plist>
