Apple Distribution 与 iPhone Dist

Xcode 11 supports the new Apple Development and Apple Distribution certificate types. These certificates support building, running, and distributing apps on any Apple platform. Preexisting iOS and macOS development and distribution certificates continue to work, however, new certificates you create in Xcode 11 use the new types. Previous versions of Xcode don’t support these certificates

大体意思就是：
Xcode11以上支持新的证书类型 Apple Distribution，但是同时也支持iPhone & macOS，但是如果是新建证书只支持Apple Distribution，也就是说Xcode11 以上版本支持所有类型的证书，但是新建的话只支持Apple xxxx
