chmod u+x Scripts/install.sh && Scripts/install.sh

• Select target p2p_wallet (if Detect Unused Code is selected by default after xcodegen)

Localization

• Download LocalizationHelper app
• Copy LocalizationHelper to Applications
• After xcodegen, the LocalizationHelper stopped working, so here is the solution:

1. Click "Open..."
2. Choose Tuist project instead of Default project

3. Choose project root folder (p2p-wallet-ios)
4. Resouces folder must be p2p-wallet-ios/p2p_wallet

5. Click open project.

CI/CD

• Swiftgen for automatically generating strings, assets.
• Swiftlint, SwiftFormat for linting, automatically formating code
• Periphery for detecting dead code (use Detect Unused Code target and run)
• CircleCI or GithubAction: implementing...

Feature Flags

Add feature flag steps

• Add feature flag to Firebase Remote Config with style: settingsFeature
• Add feature flag with the same title to public extension Feature struct

public extension Feature {
    static let settingsFeature = Feature(rawValue: "settingsFeature")
}

• Add feature flag to DebugMenuViewModel

extension DebugMenuViewModel {
    enum Menu: Int, CaseIterable {
        case newSettings

        var title: String {
            switch self {
            case .newSettings:
                return "New Settings"
            }
        }

        var feature: Feature {
            switch self {
            case .newSettings:
                return .settingsFeature
            }
        }
    }
}

Feature flag using example

if available(.settingsFeature) {
    showNewSettingsScreen(
        input: input,
        state: status.creditState
    )
} else {
