If that comes to pass it may well be useful for extensions to have a name that can be used to refer to the extension during initialization. I discussed possible syntax for that in my draft proposal for partial initializers (which I tabled for Swift 3, but may revive in the future). > ... > > -Michael > >> Am 16.05.2016 um 18:26 schrieb Brandon Knope via swift-evolution >> <[email protected]>: >> >> I like to separate methods into their own logical extensions so similar >> methods are grouped together.
