Hi, I think. We need one more thing. We may add use tap gesture on label ( priceLabel ) to launch app. Please let me update your project.

First and foremost we need to add gesture method of viewDidLoad

    // use tap gesture on label to launch app
    priceLabel.isUserInteractionEnabled = true;
    let tapGesture = UITapGestureRecognizer(target: self, action: #selector(TodayViewController.doLaunchApp))
    priceLabel.addGestureRecognizer(tapGesture)

Second, we need to add doLaunchApp function.

func doLaunchApp() {
    if let url = URL(string: "Crypto://") {
        self.extensionContext?.open(url, completionHandler: nil)
    }
}

Last, We need update pList file .

    <key>CFBundleURLTypes</key>
    <array>
        <dict>
            <key>CFBundleURLSchemes</key>
            <array>
                <string>Crypto</string>
            </array>
        </dict>
    </array>

Best

Hello, at first I would like to thank you for all your guides they are awesome. Secondly I would like to ask if this framework (CryptoCurrencyKit.framework) is open source meaning that I can use it to build my own apps and re-distribute them. I just need the values not the app that we build here in the tutorial.

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I added in TodayViewControllerTests.swift file imorting:
@testable import MyAppWidget

Could anybody help me?
