scenario: have existing ios 9.3 application 5th-generation itouch can handle. i want add ios 10-savvy code application , able filter existing code can continue working old itouch. however, compiler refuses build if deployment target set @ ios 9.3 or lower: there work-around or must create new application? possible solution: 1. build ios 10.0+ deployment; then 2. filter via in-code @available(ios 10.0, *). itouch can't handle ios 10; i'm hope above solution work. you use #available if #available(ios 10, *) { uiapplication.shared.open(url, options: [:], completionhandler: { (success) in guard success else { //handle error return } }) } else { _ = uiapplication.shared.openurl(url) } }
