Answer 1

I've created BundleInfoVersioning swift package to help me solve this issue.

It works with all keys in the info dictionary, like CFBundleVersion or CFBundleShortVersionString and with custom key paths like, for example, NSAgora/DatabaseVersion.

Examples:

let bundleInfoVersioning = BundleInfoVersioning(bundle: .main)

bundleInfoVersioning.check(forKeyPath: "CFBundleVersion") { (old: String?, new: String?) in
    if old == nil {
        Analytics.install(version: new)
    }
    else {
        Analytics.update(from: old, to: new)
    }
}

bundleInfoVersioning.check(forKeyPath: "CFBundleShortVersionString") { _ , newVersion in
    self.showWhatsNew(in: newVersion)
}

bundleInfoVersioning.check(forKeyPath: "NSAgora/DatabaseVersion") { (old: Int?, new: Int?) in
    self.resetDataBase()
}
