makeFieldEntry not compiling

[grosch]

I was using this as one of my fieldEntries() items:

makeFieldEntry(keyPath: \.contractStart, label: "Monthly Rate:", isOptional: true),

As of beta 3 that no longer compiles. It underlines the keypath and says type of expression is ambiguous without more context. If I remove the isOptional field it compiles.

I renamed isOptional to isRequired. I mentioned this in the release notes :). It was in response to #9.
