So Objective-C has the following methods of NSString:
- initWithContentsOfFile:encoding:error:
- writeToFile:atomically:encoding:error:
These are directly bridged to Swift's NSString:
convenience init(contentsOfFile path: String, encoding enc: UInt)
func write(toFile path: String, atomically useAuxiliaryFile: Bool, encoding enc: UInt)
Having seen an example of these functions used directly with Swift's String type I see that String has:
init(contentsOfFile path: String, encoding enc: String.Encoding)
While StringProtocol has:
write<T>(toFile path: T, atomically useAuxiliaryFile: Bool, encoding enc: String.Encoding) throws where T : StringProtocol
My issue is not with their definitions or usage, but with their discovery via documentation. Specifically, for the write in StringProtocol. Since this method can be used both on String and Substring, shouldn't they be documented under those structures as well and not just the StringProtocol protocol?
I imagine this is not the only case like this...
