[swift-users] Help need with SR-1187

Hi Everybody, I am trying to build the example-packages but I am getting errors once I try to run test I was hopping to add some tests to close https://bugs.swift.org/browse/SR-1187 I am using the 3-24 snapshot but I am getting import errors : error:

Re: [swift-users] NSMutableData's init?(length length: Int) initializer

It's easy to test this in a playground on OS X: NSMutableData(length: 1000) // returns nil It makes sense that the swift-corelibs-foundation version of NSMutableData should work the same way. Jacob On Thu, Apr 14, 2016 at 11:56 AM, Jens Alfke via swift-users < swift-users@swift

Re: [swift-users] Can't extend a generic type with a non-protocol constraint?

You know… if protocols could define which types can implement them, that could be made to be the same thing: protocol _String {…} `syntax which restricts instances of _String to be a` String extension Dictionary where Key: _String {…} //Same as "where Key == String”, because that’s the o

[swift-users] Can't extend a generic type with a non-protocol constraint?

It appears that you can’t extend a generic class/struct with a requirement that a type parameter inherit from a non-protocol: extension Dictionary where Key : String { … } The above produces the error “Type ‘Key’ constrained to non-protocol type ‘String’”. So is there a way I can add a m

[swift-users] NSMutableData's init?(length length: Int) initializer

Hello Guys, Girls, Do you know why is the init?(length length: Int) NSMutableData's initializer failable? The memory allocation can fail, but I think Swift doesn't handle that cases. (it is not a real issue in a modern OS) The code on github calls a non failable initializer. https://github.com/a
