Just published: VSTS Extension Token Comparer

Jasper Gilhuis

Today I published a new Visual Studio Marketplace extension named “Token Comparer”. In this post I will quickly highlight its features and its usage. In a future post will do and end-to-end scenario so in which you will learn about the creation process as well as the delivery process. But first let’s see the extension.

What does the Token Comparer do?

The Token Comparer can parse specified source files for usage of Tokens and it can compare these against available variables defined in your Release Definition. It will detect and compare the results. Based on the settings you can choose to fail, warn or continue your release.

The tasks will provide you with a summary that will show the findings. The list states the findings.

VSTS Token Comparer Summary

Configuring the Token Comparer?

In this version I choose to let you define a generic service endpoint to allow safely storing your credentials. Now VSTS has the ability to access an oAuth token this will be changed in a future version.

How to find the Token Comparer Extension

Navigate to your VSTS Team Project. Click the Marketplace icon. Search for “Token Comparer”. Choose to install it to your VSTS account.

Happy Releasing!

Removing duplicate elements from a Swift array

Lammert Westerhoff

Today I had to remove duplicate items from an Array while maintaining the original order. I knew there was no standard uniq function in Swift so I Googled a bit and found some implementations on StackOverflow. I found some good implementations, but wasn’t completely satisfied with any of them. So of course I tried to see if I could make something myself that I would be satisfied with.

Experimenting with Swift and UIStoryboardSegues

Lammert Westerhoff

Lately I've been experimenting a lot with doing things differently in Swift. I'm still trying to find best practices and discover completely new ways of doing things. One example of this is passing objects from one view controller to another through a segue in a single line of code, which I will cover in this post.

Animate constraints with a simple UIView extension in Swift

Lammert Westerhoff

iOS Developers that are getting started with Auto Layout for the first time often run in trouble once they try to animate their views. The solution is quite simple, but in this post I'll create a simple Swift extension that makes it even easier.

Full width iOS Today Extension

Lammert Westerhoff

Apple decided that the new Today Extensions of iOS 8 should not be the full width of the notification center. They state in their documentation:

Because space in the Today view is limited and the expected user experience is quick and focused, you shouldn’t create a widget that's too big by default. On both platforms, a widget must fit within the width of the Today view, but it can increase in height to display more content.

Source: https://developer.apple.com/library/ios/documentation/General/Conceptual/ExtensibilityPG/NotificationCenter.html

This means that developers that create Today Extensions can only use a width of 273 points instead of the full 320 points (for iPhones pre iPhone 6) and have a left offset of the remaining 47 points. Though with the release of iOS 8, several apps like DropBox and Evernote do seem to have a Today Extension that uses the full width. This raises question wether or not Apple noticed this and why it came through the approval process. Does Apple not care?

Should you want to create a Today Extension with the full width yourself as well, here is how to do it (in Swift):

override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(animated)
    if let superview = view.superview {
        var frame = superview.frame
        frame = CGRectMake(0, CGRectGetMinY(frame), CGRectGetWidth(frame) + CGRectGetMinX(frame), CGRectGetHeight(frame))
        superview.frame = frame
    }
}

This changes the super view (Today View) of your Today Extension view. It doesn't use any private Api's, but Apple might reject it for not following their rules. So think carefully before you use it.

iOS Today Widget in Swift - Tutorial

Lammert Westerhoff

Since both the new app extensions of iOS 8 and Swift are both fairly new, I created a sample app that demonstrates how a simple Today extension can be made for iOS 8 in Swift. This widget will show the latest blog posts of the Xebia Blog within the today view of the notification center.

The source code of the app is available on GitHub. The app is not available on the App Store because it's an example app, though it might be quite useful for anyone following this Blog.
