Xcode11.1 Release notes, Known Issues

There is an issue with UITabBarController where decoding an instance from a storyboard will create some extra views at the left end of the screen. Developers may remove these by applying a workaround. (55310448)

Workaround: To remove the extraneous views from Storyboard, create a subclass of a UITabBarController and add the following snippet in the class’s init(coder:) method:

class WorkaroundTabBarController: UITabBarController {

    required init?(coder: NSCoder) {
        super.init(coder: coder)

        // This must be run immediately after the call to super.
        if (tabBar.subviews.count > 1) {
            tabBar.subviews[0].isHidden = true
        }
    }
}

これ👇良くわからない

UITableViewCell labels in storyboards and XIB files do not use localized string values from the strings file at runtime. (52839404)

Error Handling in Swift Combine Framework

https://www.vadimbulavin.com/error-handling-in-swift-combine-framework/?utm_campaign=iOS%2BDev%2BWeekly&utm_medium=web&utm_source=iOS%2BDev%2BWeekly%2BIssue%2B424

replaceError(with:): エラーを値に変換.
- error: Never を使いたいとき?
catch(_:): エラーを Publisher に変換
mapError(_:): エラーを別のエラーに変換
- status code= 404, 500 とかのネットワークレイヤエラーをアプリケーションレイヤのエラーに変換するとか

let network404Publisher = Result<Void, NetworkError>.Publisher(._404)

/// replaceError(with:)
let r1: Result<Void, Never>.Publisher = network404Publisher
    .replaceError(with: ())

/// map(_:)
let r2: Result<Int, NetworkError>.Publisher = network404Publisher
    .map { _ -> Int in
        1
    }

/// mapError(_:)
let r3: Result<Void, とあるError>.Publisher = network404Publisher
    .mapError { networkError -> とあるError in
        switch networkError {
        case ._404:
            return .invalidEmail(message: "404だよ")
        }
    }

/// catch(_:)
let r4: Result<String, とあるError>.Publisher = network404Publisher
    .catch { networkError -> Result<String, とあるError>.Publisher in
        return .init(.invalidEmail(message: "なんかのエラー"))
}

Xcode11.2 beta release noteより

Fixed an issue with UITabBarController where decoding an instance from a storyboard would create extra views at the left end of the screen. If you worked around this issue on Xcode 11.0 or 11.1 by creating a subclass of UITabBarController and hiding extra views in the initializer you can remove the workaround. (55310448)
