All App Store Apps Required to Have a Privacy Policy: Starting October 3rd

Starting October 3, 2018, App Store Connect will require a privacy policy for all new apps and app updates in order to be submitted for distribution on the App Store or through TestFlight external testing.

2. Under App Store, click on App Information.
3. In the top right corner, add your privacy policy link for iOS apps or macOS apps, or enter text directly for tvOS apps.
4. Click Save.

Defer Statement: How to use it in Swift!

Here is a hidden gem in Swift called defer. Defer allows you to defer (no surprises there!) execution of a block of code until the end of the current scope is reached.

func updateImage() {
    defer { print("Did update image") }
    print("Will update image")
    imageView.image = updatedImage
Above code prints the folowing :
// Will update Image
// Did update image

The most common use case seen around is opening and closing a context, for example when handling access to files. A FileHandle requires to be closed once the access has been finished. You can benefit from the defer statement to ensure you don’t forget to do this.

Make Your iOS App ‘Feel’ Better: A Guide Over Taptic Engine & Haptic Feedback!

If you have watched the wonderful WWDC 2017 talk about designing sound for apps then you will know how much impact sound can have on the app’s user experience. With the release of the iPhone 6S and 6S Plus, Apple introduced Taptic Engine which provides tactile sensations in the form of vibrations (called haptic signals.) and along with it came a suite of API’s that developers can harness to make big usability improvements. Check out the article linked below which goes in depth into the API.

App Store: Are app reviews worth reading?

App reviews are highly opinion based and not fact based and normally not a great way to gauge if an app is good or bad. They sure can be helpful (for a developer), but most reviews are composed of biased rants and half-legible reviews which are hard to sift through. Sadly, most people judge an app just by looking at the app’s review scores even though it does not actually reflect the quality of an app.

People want to be heard, and giving a 1-star or 5-star rating adds oomph to your opinion.

Check out this fantastic article by John Saito who has sifted through 1000’s of app reviews to provide his take on app store reviews. Quote from the article:

After crunching the numbers, I found that over 70% of our app reviews were either 5-star or 1-star reviews. Over two-thirds of reviewers either loved or hated our app.
