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 some nice things in

100 Days of SwiftUI — Day 22

Today was another challenge day [https://www.hackingwithswift.com/100/swiftui/22], this means: I had to change some code of the GuessTheFlag-project and answer some questions afterwards. It didn't take a lot of time and right now, on a friday evening, I'm quite happy about it. I partially solved

100 Days of SwiftUI — Day 21

After playing around with colors and gradients yesterday [https://zeitschlag.net/100-days-of-swiftui-day-20/], I just finished the 21st part [https://www.hackingwithswift.com/100/swiftui/21]. I learned about some more modifiers today. For example, adding shadows to elements is pretty easy in SwiftUI. And adding shapes. And borders. I still

100 Days of SwiftUI — Day 20

I just finished Day 20 [https://www.hackingwithswift.com/100/swiftui/20] — and it unexpectedly totally brightened my day! Today was the introduction day for the second project. Paul talked about the different stack types in SwiftUI, button, alert — and colors and gradients. And suddenly, I couldn't resist anymore, I

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 [https://zeitschlag.net/me-my-future-self-and-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,

Running Tests in pre-commit hooks and alternatives

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 [https://support.apple.com/keyboard-service-program-for-mac-notebooks]. And to make myself feel better, 'cause you never know what might happen in the

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 [https://twitter.com/_Caro_N/status/1017364995481440257] do these days. Typically, our code looks

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 [http://thebugcode.github.io/when-to-self-in-swift-and-when-not-to-2/] and recommended me to use self in Swift sparingly and only when necessary for the compiler. But back in 2012 I started to

preconditionFailure

One of my goals for May 2018 was to finally read The Pragmatic Programmer [https://pragprog.com/book/tpp/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
