Working around the “Untrusted Developer” bug on iOS 15

Part of the iOS 15 Bugs series. One of the must infuriating bugs, for me, on iOS 15 is that I can't run my own software on my phone. I can install my app via Xcode, but running it presents this dialog, and crucially nowhere in Settings can …

Checking in on iOS 15 bugs, as of 15.0.2

tl;dr: it's still buggy.

More Bugs in iPhone 13 & iOS 15

Part of the iOS 15 Bugs series. Since my last post, I've bought a new iPhone 13. I've encountered some new bugs, along with some old ones I expected a new phone to solve. A recurring theme for me: Apple's hardware is great. Their …

iOS 15 & Safari 15

Part of the iOS 15 Bugs series. iOS 15 is out. Overall I'm happy-ish with it, but I've run into some bugs/annoyances. A lot of these are around Focus Modes, which is maybe the iOS 15 feature I've played with most so far. …

App Transport Security: What, Why, How?

In this talk, I answer all your questions about App Transport Security: What is it? Why does it matter? How do you make your server compatible with it, and how do you configure your app to talk to non-compliant servers? Which other apps are using ATS?

Working with custom UIView designated initializers

Greg Titus on NSFileCoordination and Extensions

It does work, but you have to be careful.

iOS 8 Extensions Roundup

I’m excited to start using iOS 8 extensions, but it’s looking like it’ll be a rough ride for a little while.

Including your Pods directory in source control

On my current project, we made the decision a month or so ago to add our Pods directory to git. The team has seen a number of benefits from this decision. There are certainly some negatives, but in our experience the positives have been huge, immediately tangible, and well worth …

CDZLinkOpenManager

Part of the Project Announcements series. Update: the software described in this post is no longer maintained. While developing BuyVM Manager, I built a little framework that allows your app’s users to select a default browser, and open links from your app in that browser. It’s now on …

CDZPinger

Part of the Project Announcements series. Update: the software described in this post is no longer maintained. While writing BuyVM Manager, I was disappointed to find there was no good, easy-to-use ICMP ping library for iOS projects. Apple provides a SimplePing code sample that you can adapt into your codebase, …

Elegant UITableView row selection behavior based on edit state

If you're a Cocoa Touch developer, you've undoubtedly implemented -[UITableViewDelegate tableView:didSelectRowAtIndexPath:] a few hundred times. I did this recently and needed different behavior based on whether the table view was in its editing state (whether -[UITableView isEditing]). In this particular case, the best …
