Cheap and dirty

This started as a two-toot-thread on my Mastodon but I couldn't resist the urge to write a few more words. Luckily, I have a blog. This will be about crappy SwiftUI and so this won't be the last post about it.

Popover on iPad with a custom content size

On an iPad-app I had to set a custom content size of a modal sheet and took the wrong of two options. I had to learn again, that reading the documentation can save me some time.

Mastodon for iOS. Year One.

I've worked on Mastodon for iOS for over one year now. What happened during that year? What did I do? Time to look back!

You will always be remembered!

We changed the Welcome-screen in the Mastodon-app for iPhone and iPad. The old screen was fancy and so is the new one.

Open Mobile Maps for iOS

A native mobile SDK for OpenStreetMap-map-data on iOS and Android.

Reorder some rows but not all

I'm still writing iOS-apps using Swift and UIKit instead of SwiftUI — I've never been one of those cool kids using the latest tech, and my 100 days of SwiftUI lasted for 33 days or so. Maybe I should give it another chance. But today I found

AsyncOperation

A few days ago, I was working on an app for a client. With this app you can basically see a staff roster, that needs to be downloaded from a server. The REST-API is built that way, that the app has to talk to different endpoints to download all the

It's self again

Nearly two years ago, I wrote a short piece about self. Since then, a lot has changed: I got fired, found a new job, quit, and found another new job. I'm working from home now as employee of a fully distributed company. To reflect on that, I'

A few months ago, I bought myself a fancy MacBook Pro. You know, one of those fancy devices with the fancy TouchBar, a nice Retina screen and a broken-by-default keyboard. And to make myself feel better, 'cause you never know what might happen in the next couple of years,

isActive = true vs. NSLayoutConstraint.activate

The whole UI of the app, I helped to develop, is written in code. No Storyboards, no XIBs, just Swift. Someone made this decision looooong ago. Nevertheless, we're using AutoLayout, just like every cool kid should do these days. Typically, our code looks like this: self.titleLabel.topAnchor.

Me, my future self and self

A colleague of mine complained, that I use self too much. In Objective-C, it was everywhere, but he sent me this blogpost and recommended me to use self in Swift sparingly and only when necessary for the compiler. But back in 2012 I started to learn Objective-C. Until 2015 it

preconditionFailure

One of my goals for May 2018 was to finally read The Pragmatic Programmer. I haven't succeeded yet, that's why this year, June was May, Extended Edition and July is June, Extended Edition. A few years ago, a dear friend of mine recommended reading this book
