Just improved the gist with the help of @WdKay so that views can be counted individually.

Interested in inspecting how many times a SwiftUI view body is evaluated? Here is a gist that might help: https://t.co/OC3Wqz13TF

@cocoafrog Instruments also groups events by view type, so when several instances are simultaneously on screen I find it easier to find out what happens with each one of them.

But of course I still find SwiftUI Instruments tools invaluable in other scenarios.

[Samuel Défago @defagos]

@cocoafrog I quite like being able to understand how the UI I am working on behaves at a glance, but Instruments mostly logs tons of events that lack a consolidated view AFAIK. This is why I wrote this helper.

[Samuel Défago @defagos]

This is obviously inspired by body counters shown in Swift Playgrounds, but here displayed in your running app instead.

Finding myself embedding SwiftUI code into UIKit again, so here is a friendly reminder there is a simple way to send actions down the UIKit responder chain starting from a SwiftUI view

I made a Dash docset out of @defagos' post on SwiftUI layout behavior, for quick reference. Hope you are ok with that Samuel!

@manuelmaly That's really kind of you, thank you very much!

Tip:

You can capture the projected value of a @Published property (i.e. its associated publisher) in a capture list to incorporate user-driven sources of change into a pipeline declaration.

I recently published an article discussing a way to build scalable declarative data pipelines using Combine.

Could make for an interesting read near the fireplace if you missed my announcement tweet.

Gathering data in an app can be a challenge, especially when several sources must be aggregated or when pagination is involved.

My latest article discusses how Combine and reactive programming provide a declarative and scalable solution to this problem: https://t.co/CNxnoRYpDp

[Samuel Défago @defagos]

Two years ago I would never have considered using reactive programming to write apps.

I am now asking myself how I could live without it before, and I hope you'll understand why after having read my article.

Probably my biggest aha moment as an Apple developer.

I just published an article about SwiftUI layout behaviors. If you are interested in learning more about SwiftUI layout principles this might be worth a read. Includes a view taxonomy covering SwiftUI built-in views in greater detail: https://t.co/itntvZN65O

[Samuel Défago @defagos]

Are you using `continuousGroupLeadingBoundary` as `orthogonalScrollingBehavior` in a compositional collection view layout?

🎉 iOS 14.5 fixes:

- Scroll interruptions experienced during reloads.
- Snapping on the last item (if non-integral number of items visible horizontally).

Having issues with crash log symbolication recently in projects enabled for bitcode? Does your project use SPM 5.3 to integrate packages containing resources? https://t.co/XErkkiAVnr

[Samuel Défago @defagos]

Known remaining issues affecting binary Swift packages seem to have been resolved in Xcode 12.2 beta 3: https://t.co/uEAWX7UPfK /cc @steipete

[Samuel Défago @defagos]

@antiraum Thanks for the info. My sample project works also correctly on iOS 14.2 beta 3. Seems promising 🤞

[Samuel Défago @defagos]

If your application plays video or audio content, beware that iOS 14 introduced a leak and changes possibly impacting background playback support.

[Samuel Défago @defagos]

@antiraum It seems the issue will be fixed in iOS 14.2. The behavior is namely correct in 14.2 beta 2 with my test device (an iPhone 7). I’ll test again with the final version and other devices, but this seems promising.

[Samuel Défago @defagos]

@0xced @pyby85 On aura probablement une beta publique quand ce sera moins en chantier, mais en attendant ça peut éventuellement faire l’affaire 😅
