This opens up a lot of possibilities and this post from GoLocalApps shows how important they are and how to find them with the free AppToolkit SDK.

Can You Make Subscriptions Work With Your App?
You may have read that subscriptions are the way to generate revenue nowadays. On the surface, it sounds great. Loyal users pay a little each month or year and you can get some recurring revenue, making your app profitable and funding further development. When you run the numbers, however, it isn't likely to work out that way. Very interesting read from Dan Counsell on the uphill battle most apps face and just how successful your app would have to be to make subscriptions work. Dan also talks about what he wishes would change on the App Store.
The idea that developers will be able to charge their users a few bucks a year and make a living from it is bonkers.

Burnout Doesn't Always Come From Being Overworked
Every so often I highlight a post on burnout, taking care of yourself, or work/life balance. We all know it's important but it's easy to feel overwhelmed with deadlines or the other stresses of life and forget to take care of ourselves. For instance, did you know that burnout can come from a job where you aren't overworked or stressed out? Before I started working independently, I definitely had burnout, though I didn't think about it that way at the time. I was tired of my job and industry, ready for a change. If you are thinking you might need a change, take a look at this post from Kieran about his struggles to recover from burnout over the last year.
The best definition of burnout I’ve come across is a chronic state of being out of sync with one or more aspects of your life.

Learning Protocols In Swift
When I first started coding for iOS I had a tough time wrapping my head around protocols. Bookmark this post to help you both understand protocols and for reference when you need to implement them in your app.
A protocol defines a blueprint of methods, properties, and other requirements that suit a particular task or piece of functionality.
