Questions tagged [iphone]
DO NOT use this tag unless you are addressing Apple's iPhone and/or iPod touch specifically. For questions not dependent on hardware, use the tag [ios]. More tags to consider are [xcode] (but only if the question is about the IDE itself), [swift], [objective-c] or [cocoa-touch] (but not [cocoa]). Please refrain from questions regarding the iTunes App Store or about iTunes Connect. If using C#, tag with [mono].
