この記事は iOS Advent Calendar 2021 の23日目の記事です。
iOS エンジニアの 加藤 です。SwiftUI で Preview を扱う際の課題を解決したので、共有します。
課題感
SwiftUI で Preview するとき、デバイス名を文字列で指定する必要がありますよね。
struct ContentView_Previews: PreviewProvider { static var previews: some View { ContentView() .previewDevice(PreviewDevice(rawValue: "iPhone 13 Pro")) } }
なんとかしたい。
したこと
previewDevice(_:) によると、% xcrun simctl list devicetypes でデバイス一覧が取得できるようです。
取得した文字列を整形して enum にする、Alfred の Workflow を作りました。
これで、最新のデバイスリストが enum としてコピーできます。 中身は正規表現と簡単なRubyなので、ご自由に編集してください。
結果
嬉しい😀
Xcode 13.0 時点でコピーできる文字列
enum Device: String, CaseIterable { case iPhone_4s = "iPhone 4s" case iPhone_5 = "iPhone 5" case iPhone_5s = "iPhone 5s" case iPhone_6_Plus = "iPhone 6 Plus" case iPhone_6 = "iPhone 6" case iPhone_6s = "iPhone 6s" case iPhone_6s_Plus = "iPhone 6s Plus" case iPhone_SE_1st_generation = "iPhone SE (1st generation)" case iPhone_7 = "iPhone 7" case iPhone_7_Plus = "iPhone 7 Plus" case iPhone_8 = "iPhone 8" case iPhone_8_Plus = "iPhone 8 Plus" case iPhone_X = "iPhone X" case iPhone_Xs = "iPhone Xs" case iPhone_Xs_Max = "iPhone Xs Max" case iPhone_Xʀ = "iPhone Xʀ" case iPhone_11 = "iPhone 11" case iPhone_11_Pro = "iPhone 11 Pro" case iPhone_11_Pro_Max = "iPhone 11 Pro Max" case iPhone_SE_2nd_generation = "iPhone SE (2nd generation)" case iPhone_12_mini = "iPhone 12 mini" case iPhone_12 = "iPhone 12" case iPhone_12_Pro = "iPhone 12 Pro" case iPhone_12_Pro_Max = "iPhone 12 Pro Max" case iPhone_13_Pro = "iPhone 13 Pro" case iPhone_13_Pro_Max = "iPhone 13 Pro Max" case iPhone_13_mini = "iPhone 13 mini" case iPhone_13 = "iPhone 13" case iPod_touch_7th_generation = "iPod touch (7th generation)" case iPad_2 = "iPad 2" case iPad_Retina = "iPad Retina" case iPad_Air = "iPad Air" case iPad_mini_2 = "iPad mini 2" case iPad_mini_3 = "iPad mini 3" case iPad_mini_4 = "iPad mini 4" case iPad_Air_2 = "iPad Air 2" case iPad_Pro_9_7inch = "iPad Pro (9.7-inch)" case iPad_Pro_12_9inch_1st_generation = "iPad Pro (12.9-inch) (1st generation)" case iPad_5th_generation = "iPad (5th generation)" case iPad_Pro_12_9inch_2nd_generation = "iPad Pro (12.9-inch) (2nd generation)" case iPad_Pro_10_5inch = "iPad Pro (10.5-inch)" case iPad_6th_generation = "iPad (6th generation)" case iPad_7th_generation = "iPad (7th generation)" case iPad_Pro_11inch_1st_generation = "iPad Pro (11-inch) (1st generation)" case iPad_Pro_12_9inch_3rd_generation = "iPad Pro (12.9-inch) (3rd generation)" case iPad_Pro_11inch_2nd_generation = "iPad Pro (11-inch) (2nd generation)" case iPad_Pro_12_9inch_4th_generation = "iPad Pro (12.9-inch) (4th generation)" case iPad_mini_5th_generation = "iPad mini (5th generation)" case iPad_Air_3rd_generation = "iPad Air (3rd generation)" case iPad_8th_generation = "iPad (8th generation)" case iPad_9th_generation = "iPad (9th generation)" case iPad_Air_4th_generation = "iPad Air (4th generation)" case iPad_Pro_11inch_3rd_generation = "iPad Pro (11-inch) (3rd generation)" case iPad_Pro_12_9inch_5th_generation = "iPad Pro (12.9-inch) (5th generation)" case iPad_mini_6th_generation = "iPad mini (6th generation)" case Apple_TV = "Apple TV" case Apple_TV_4K = "Apple TV 4K" case Apple_TV_4K_at_1080p = "Apple TV 4K (at 1080p)" case Apple_TV_4K_2nd_generation = "Apple TV 4K (2nd generation)" case Apple_TV_4K_at_1080p_2nd_generation = "Apple TV 4K (at 1080p) (2nd generation)" case Apple_Watch_38mm = "Apple Watch - 38mm" case Apple_Watch_42mm = "Apple Watch - 42mm" case Apple_Watch_Series_2_38mm = "Apple Watch Series 2 - 38mm" case Apple_Watch_Series_2_42mm = "Apple Watch Series 2 - 42mm" case Apple_Watch_Series_3_38mm = "Apple Watch Series 3 - 38mm" case Apple_Watch_Series_3_42mm = "Apple Watch Series 3 - 42mm" case Apple_Watch_Series_4_40mm = "Apple Watch Series 4 - 40mm" case Apple_Watch_Series_4_44mm = "Apple Watch Series 4 - 44mm" case Apple_Watch_Series_5_40mm = "Apple Watch Series 5 - 40mm" case Apple_Watch_Series_5_44mm = "Apple Watch Series 5 - 44mm" case Apple_Watch_SE_40mm = "Apple Watch SE - 40mm" case Apple_Watch_SE_44mm = "Apple Watch SE - 44mm" case Apple_Watch_Series_6_40mm = "Apple Watch Series 6 - 40mm" case Apple_Watch_Series_6_44mm = "Apple Watch Series 6 - 44mm" case Apple_Watch_Series_7_41mm = "Apple Watch Series 7 - 41mm" case Apple_Watch_Series_7_45mm = "Apple Watch Series 7 - 45mm" }
