Release 2.0.4 v.s. Xcode 16 #32
Description
Anyone also ran into a potential incompatibility issue with Xcode 16? I am getting the following error, and wonder if there is a workaround or a working-in-progress branch that I can switch to? Thanks.
Redundant conformance requirements in signature <Self where Self : UnmanagedModel>:
Ours:
- RepositoryManagedModel
- Copyable
- Escapable
Theirs:
- RepositoryManagedModel
All requirements:
(requirement "Self" conforms_to "Equatable")
(requirement "Self" same_type "Self.[UnmanagedModel]RepoManaged.[RepositoryManagedModel]Unmanaged")
(requirement "Self.[UnmanagedModel]RepoManaged" conforms_to "RepositoryManagedModel")
(requirement "Self.[UnmanagedModel]RepoManaged" conforms_to "Copyable")
(requirement "Self.[UnmanagedModel]RepoManaged" conforms_to "Escapable")
Requirement machine for <τ_0_0 where τ_0_0 : UnmanagedModel>
