You know the feeling. You're refactoring that old ViewController that’s still in Objective-C, and you get to that part where you need to extract an async call to a new class. And you’ve gotten so used to closures in Swift that you're using them to solve problems instead of delegates, even in Objective-C. And you say to yourself, “I know—I’ll use a block.”
I came into work Monday to see our builds failing with a problem that was unconnected to anything we merged recently. Reading the logs, I could see that fastlane's
gym was claiming that our scheme was not found in the workspace, but I knew that it was definitely there.
When I wrote about whether iOS developers needed to know Android to be successful, I had an instinct that the answer was no, and I did a spot-check of job-boards to make sure I wasn’t way off. Here’s a more in-depth look with links so you can check to make sure it still holds at a later date (my numbers are as of February 2018).
There's a bug that happens around New Years in a few apps (including Apple's). It's simple to avoid, but you need to submit a fix soon to beat the App Store holiday.
You’ve done the Stanford iOS course and all of the Wenderlich Auto Layout tutorials, but your app is still dumping
Unable to simultaneously satisfy constraints. Probably at least one of the constraints in the following list is one you don't want
to the console.
On Tuesday, Apple announced the iPhone X, described as “an iPhone that is entirely screen.” On closer inspection, though, the screen does appear to missing a little something.
Sometimes you really care that your app is in the App Store on a specific date. You might think that submitting a week before is enough time, but it’s not if you get rejected. You can’t prepare for every eventuality, but there is one thing you can do that might help
Storyboards get a bad rap. Sure, they are impossible to test and code review, and merges are a real pain. But it takes a second to look at a Storyboard and visualize what the UI is going to look like (or even if you are in the right file). If only there was a way to preserve the visualization but dump the XML.
If you are just starting your career and started with iOS and never learned anything about the web, it doesn’t hurt to know something about other platforms.
These are the top three web technologies you should have some familiarity with, even if you are in Xcode 100% of the time making a native app.
Ok, so you have a view controller that brings up another view controller. Let’s call the first one
FirstVC and the second one
FirstVC either presents
SecondVC or there is some segue that it uses to bring it up.
There’s this myth in the iOS community that “professional” iOS developers never use Interface Builder. It’s meant to imply that coding your interfaces is always better, and if you don’t do it, you are somehow less of a programmer. The myth perpetuates the idea that IB is a crutch, a toy, something that only newbies use.
I call BS.
