This is the latest in a series of articles explaining how iOS and Watch apps appear when run on hardware that didn’t exist when they were designed and built.On 20th September 2021, Apple announced a 6th Generation iPad Mini with an...

IntroductionIn WWDC 2021: What’s New in SF Symbols, Apple announced SF Symbols 3. There are approximately 660 new symbols, multicolor symbols now work correctly in UIKit, and there are two new rendering modes with enhanced color...

SF Symbols Changes in iOS 14.5IntroductionFor a detailed list of symbols that were added or renamed in SF Symbols 2, please refer to my earlier article SF Symbols Changes in iOS 14. For changes in iOS 14.2 see SF Symbols Changes in...

> So I wanna ask will 5px system got troubles when rendering?I’m a developer, not a designer, so I don’t really have any advice to give you. Remember that the sizes are in points, not pixels,

The point of the algorithm is to be general purpose and work for any data that can be represented as lists of lists of words (not just for symbol names) and to allow the search tokens to be in any order: a search for “b x” will find...

IntroductionThis article describes a simple, smart search algorithm that I have used in several iOS apps. The algorithm is smarter than a trivial substring match but not as complex as something like Xcode’s fuzzy matching of method names....

I just delete the Xcode.app from /Applications and don’t mess around with any other files! Caches should be OK, as they would (presumably) be re-created if necessary.However, it’s certainly possible that some supporting files are shared...

IntroductionFor a detailed list of symbols that were added or renamed in SF Symbols 2, please refer to my earlier article SF Symbols Changes in iOS 14.On November 21st 2020, Mike Stern (Platform Experience and Design Evangelism Manager at...

Over the last few years I have written several articles showing how iOS apps built with different versions of Xcode would appear when run on iOS devices that didn’t exist when the apps were built. As a general rule, apps must build with...

Thanks! It’s actually pretty hard to implement the names in an enum or other static mechanism because some names are prefixes of others. e.g. “circle” and “circle.fill”. What type is ‘.circle’ that will be acceptable as a symbol name and...

The primary view controller is wider than what is visible on screen to provide extra content when over-scrolling during a swipe action. It is 420 points wide, but 320 points is visible. So content that is aligned with the leading edge...

IntroductionIn WWDC 2019: 206, Introducing SF Symbols Apple announced a great new resource for iOS developers:SF Symbols introduces a comprehensive library of vector-based symbols that you can incorporate into your app to simplify the...

> The first [base] one being the window’s main content and the last one [elevated] anything above itThis isn't quite true.1. An iPad app shown in Slide Over or Split View Multitasking will always be elevated (even the main...

Xcode 9.4 has been deprecated for a long time and you won’t be able to submit new app versions to App Store Connect using it (nor Xcode 10 for that matter!).The only possible reason I can think of for trying to use Xcode 9.4 today is to...

> but 11.4 is just not working with our current development environmentThat is perhaps the problem you ought to be focusing on 😀

I’m not sure I understand the question. If you kill the simulator and Xcode, open a particular version of Xcode and then launch the simulator I think it runs the simulator corresponding to that Xcode version. You can also run multiple...

IntroductionAdaptivity is an app which helps developers and designers visualise how iOS’s Size Classes and margins for layout, readable content and the safe area look on real devices and how they change with respect to orientation, iPad...

I’m not sure what value it has, but you can use a UIAdaptivePresentationControllerDelegate to disable the default adaption from a form/page sheet to full screen in a compact width environment. It’s not quite the same (the presenting view...

IntroductionSome apps store personal or sensitive information. For example, my Medical ID Record app stores a comprehensive record of your medical information. This is very private information which the user does not want to be...

That should work, but I think you would have to remeber to add swift files to the main app target and that empty host target to make code available to the tests. It might also be more complicated if you have other frameworks you need to...

IntroductionBy default, when Xcode runs unit tests it uses your main app target as a host application and effectively injects your test code into your app at run time. This makes it easy for your unit tests to refer to types and methods...

I’ve never written a Share Extension, so don’t know what to suggest except that you probably need to change your code to work with the way they are presented.

This is the latest in a series of articles explaining how iOS and Watch apps appear when run on hardware that didn’t exist when they were designed and built. Previous articles focused on the iPhone X, iPhone XS Max & XR, Series 4 Apple...

IntroductionAt the time of writing, WWDC 2019 is drawing to a close. Like many iOS developers I’m slowly processing all the new information that Apple threw at us and will be trying to watch as many videos as I can in the coming weeks...
